General Information

Summary

This manual discusses management of Atheros and Prism chipset based wireless NICs that comply with IEEE 802.11 set of standards. These interfaces use radio waves as a physical signal carrier and are capable of data transmission with speeds up to 108 Mbps (in 5GHz turbo-mode).

MikroTik RouterOS supports the Intersil Prism II PC/PCI, Atheros AR5000, AR5001X, AR5001X+, AR5002X+, AR5004X+ and AR5006 chipset based cards for working as wireless clients (station mode), wireless bridges (bridge mode), wireless access points (ap-bridge mode), and for antenna positioning (alignment-only mode). For furher information about supported wireless adapters, see Device Driver List

MikroTik RouterOS provides a complete support for IEEE 802.11a, 802.11b and 802.11g wireless networking standards. There are several additional features implemented for the wireless networking in RouterOS - WPA/WPA2 (Wi-Fi Protected Access), WEP (Wired Equivalent Privacy), software and hardware AES encryption, EAP authenticaton, WDS (Wireless Distribution System), DFS (Dynamic Frequency Selection), Alignment mode (for positioning antennas and monitoring wireless signal), VAP (Virtual Access Point), ability to disable packet forwarding among clients, Nstreme wireless transmission protocol and others. You can see the table of features supported by different cards.

The Nstreme protocol is MikroTik proprietary (i.e., incompatible with other vendors) wireless protocol aimed to improve point-to-point and point-to-multipoint wireless links. Advanced version of Nstreme, called Nstreme2 works with a pair of wireless cards (Atheros AR5210 and newer MAC chips only) - one for transmitting data and one for receiving.

Benefits of Nstreme protocol:

  • Client polling. Polling reduces media access times, because the card does not need to ensure the air is "free" each time it needs to transmit data (the polling mechanism takes care of it)
  • Very low protocol overhead per frame allowing super-high data rates
  • No implied protocol limits on link distance
  • No implied protocol speed degradation for long link distances
  • Dynamic protocol adjustment depending on traffic type and resource usage

Quick Setup Guide

Let's consider that you have a wireless interface, called wlan1.

  • To set it as an Access Point, working in 802.11g standard, using frequency 2442 MHz and Service Set Identifier test, do the following configuration:

    /interface wireless set wlan1 ssid=test frequency=2442 band=2.4ghz-b/g \
       mode=ap-bridge disabled=no

    Now your router is ready to accept wireless clients.

  • To make a point-to-point connection, using 802.11a standard, frequency 5805 MHz and Service Set Identifier p2p, write:

    /interface wireless set wlan1 ssid="p2p" frequency=5805 band=5ghz \
        mode=bridge disabled=no

    The remote interface should be configured to station as showed below.

  • To make the wireless interface as a wireless station, working in 802.11a standard and Service Set Identifier p2p:

    /interface wireless set wlan1 ssid="p2p" band=5ghz mode=station disabled=no

Description

The Atheros card has been tested for distances up to 20 km providing connection speed up to 17Mbit/s. With appropriate antennas and cabling the maximum distance should be as far as 50 km.

These values of ack-timeout were approximated from the tests done by us, as well as by some of our customers:

range ack-timeout
5GHz 5GHz-turbo 2.4GHz-G
0km default default default
5km 52 30 62
10km 85 48 96
15km 121 67 133
20km 160 89 174
25km 203 111 219
30km 249 137 368
35km 298 168 320
40km 350 190 375
45km 405 - -

Please note that these are not the precise values. Depending on hardware used and many other factors they may vary up to +/- 15 microseconds.

You can also use dynamic ack-timeout value - the router will determine ack-timeout setting automatically by sending periodically packets with a different ack-timeout. Ack-timeout values by which ACK frame was received are saved and used later to determine the real ack-timeout.

The Nstreme protocol may be operated in three modes:

  • Point-to-Point mode - controlled point-to-point mode with one radio on each side
  • Dual radio Point-to-Point mode (Nstreme2) - the protocol will use two radios on both sides simultaneously (one for transmitting data and one for receiving), allowing superfast point-to-point connection
  • Point-to-Multipoint - controlled point-to-multipoint mode with client polling (like AP-controlled TokenRing)

Hardware Notes

The MikroTik RouterOS supports as many Atheros chipset based cards as many free adapter slots are on your system. One license is valid for all cards on your system. Note that maximal number of PCMCIA sockets is 8.

Some chipsets are not stable with Atheros cards and cause radio to stop working. MikroTik RouterBoard 200, RouterBoard 500 series, and systems based on Intel i815 and i845 chipsets are tested and work stable with Atheros cards. There might be many other chipsets that are working stable, but it has been reported that some older chipsets, and some systems based on AMD Duron CPU are not stable.

Only AR5212 and newer Atheros MAC chips are stable with RouterBOARD200 connected via RouterBOARD14 four-port MiniPCI-to-PCI adapter. This note applies only to the RouterBOARD200 platform with Atheros-based cards.

Wireless Interface Configuration

Submenu level: /interface wireless

Description

In this section we will discuss the most important part of the configuration.

Property Description

ack-timeout (integer | dynamic | indoors) - acknowledgement code timeout (transmission acceptance timeout) in microseconds for acknowledgement messages. Can be one of these:

dynamic - ack-timeout is chosen automatically
indoors - standard constant for indoor usage

adaptive-noise-immunity (yes | no; default: yes) - adjust various receiver parameters dynamically to minimize interference and noise effect on the signal quality. Only AR6001XL and AR6001GL and newer Atheros chips support this featureallow-sharedkey (yes | no; default: no) - allow WEP Shared Key cilents to connect. Note that no authentication is done for these clients (WEP Shared keys are not compared to anything) - they are just accepted at once (if access list allows that)antenna-gain (integer; default: 0) - antenna gain in dBi. This parameter will be used to calculate whether your system meets regulatory domain's requirements in your countryantenna-mode (ant-a | ant-b | rxa-txb | txa-rxb; default: ant-a) - which antenna to use for transmit/receive data:

ant-a - use only antenna a
ant-b - use only antenna b
rxa-txb - use antenna a for receiving packets, use antenna b for transmitting packets
txa-rxb - use antenna a for transmitting packets, antenna b for receiving packets

area (text; default: "") - string value that is used to describe an Access Point. Connect List on the Client's side comparing this string value with area-prefix string value makes decision whether allow a Client connect to the AP. If area-prefix match the entire area string or only the beginning of it the Client is allowed to connect to the AParp (disabled | enabled | proxy-arp | reply-only; default: enabled) - Address Resolution Protocol settingband - operating band

2.4ghz-b - IEEE 802.11b
2.4ghz-b/g - IEEE 802.11g (supports also legacy IEEE 802.11b protocol)
2.4ghz-g-turbo - IEEE 802.11g using double channel, providing air rate of up to 108 Mbit

2ghz-5mhz - variation of IEEE 802.11g with quarter the band, and, accordingly, four times lower speed (air rate of up to 13.5Mbit)
5ghz-10mhz - variation of IEEE 802.11a with half the band, and, accordingly, twice lower speed (air rate of up to 27Mbit)
5ghz-5mhz - variation of IEEE 802.11a with quarter the band, and, accordingly, four times lower speed (air rate of up to 13.5Mbit)

basic-rates-a/g (multiple choice: 6Mbps, 9Mbps, 12Mbps, 18Mbps, 24Mbps, 36Mbps, 48Mbps, 54Mbps; default: 6Mbps) - basic rates in 802.11a or 802.11g standard. This should be the minimal speed all the wireless network nodes support (they will not be ableto connect otherwise). It is recommended to leave this as defaultbasic-rates-b (multiple choice: 1Mbps, 2Mbps, 5.5Mbps, 11Mbps; default: 1Mbps) - basic rates in 802.11b mode. This should be the minimal speed all the wireless network nodes support (they will not be ableto connect otherwise). It is recommended to leave this as defaultburst-time (time; default: disabled) - time in microseconds which will be used to send data without stopping. Note that no other wireless cards in that network will be able to transmit data during burst-time microseconds. This setting is available only for AR5000, AR5001X, and AR5001X+ chipset based cardscompression (yes | no; default: no) - if enabled on AP (in ap-bridge or bridge mode), it advertizes that it is capable to use hardware data compression. If a client, connected to this AP, also supports and is configured to use the hardware data compression, it requests the AP to use compression. This property does not affect clients, which do not support compression.country (albania | algeria | argentina | armenia | australia | austria | azerbaijan | bahrain | belarus | belgium | belize | bolvia | brazil | brunei darussalam | bulgaria | canada | chile | china | colombia | costa rica | croatia | cyprus | czech republic | denmark | dominican republic | ecuador | egypt | el salvador | estonia | finland | france | france_res | georgia | germany | greece | guatemala | honduras | hong kong | hungary | iceland | india | indonesia | iran | ireland | israel | italy | japan | japan1 | japan2 | japan3 | japan4 | japan5 | jordan | kazakhstan | korea republic | korea republic2 | kuwait | latvia | lebanon | liechtenstein | lithuania | luxemburg | macau | macedonia | malaysia | mexico | monaco | morocco | netherlands | new zealand | no_country_set | north korea | norway | oman | pakistan | panama | peru | philippines | poland | portugal | puerto rico | qatar | romania | russia | saudi arabia | singapore | slovak republic | slovenia | south africa | spain | sweden | switzerland | syria | taiwan | thailand | trinidad & tobago | tunisia | turkey | ukraine | united arab emirates | united kingdom | united states | uruguay | uzbekistan | venezuela | viet nam | yemen | zimbabwe; default: no_country_set) - limits wireless settings (frequency and transmit power) to those which are allowed in the respective country

no_country_set - no regulatory domain limitations

default-ap-tx-limit (integer; default: 0) - limits data rate for each wireless client (in bps)

0 - no limits

default-authentication (yes | no; default: yes) - specifies the default action on the client's side for APs that are not in connect list or on the AP's side for clients that are not in access list

yes - enables AP to register a client if it is not in access list. In turn for client it allows to associate with AP not listed in client's connect list

default-client-tx-limit (integer; default: 0) - limits each client's transmit data rate (in bps). Works only if the client is also a MikroTik Router

0 - no limits

default-forwarding (yes | no; default: yes) - whether to use data forwarding by default or not. If set to 'no', the registered clients will not be able to communicate with each otherdfs-mode (none | radar-detect | no-radar-detect; default: none) - used for APs to dynamically select frequency at which this AP will operate

none - do not use DFS
no-radar-detect - AP scans channel list from "scan-list" and chooses the frequency which is with the lowest amount of other networks detected
radar-detect - AP scans channel list from "scan-list" and chooses the frequency which is with the lowest amount of other networks detected, if no radar is detected in this channel for 60 seconds, the AP starts to operate at this channel, if radar is detected, the AP continues searching for the next available channel which is with the lowest amount of other networks detected

disable-running-check (yes | no; default: no) - disable running check. If value is set to 'no', the router determines whether the card is up and running - for AP one or more clients have to be registered to it, for station, it should be connected to an AP. This setting affects the records in the routing table in a way that there will be no route for the card that is not running (the same applies to dynamic routing protocols). If set to 'yes', the interface will always be shown as runningdisconnect-timeout (time; default: 3s) - time since the third sending failure ( 3*(hw-retries+1) packets have been lost) at the lowest datarate only (i.e. since the first time on-fail-retry-time has been activated), when the client gets disconnected (logged as "extensive data loss")frame-lifetime (integer; default: 0) - frame lifetime in centiseconds since the first sending attempt to send the frame. Wireless normally does not drop any packets at all until the client is disconnected. If there is no need to accumulate packets, you can set the time after which the packet will be discarded

0 - never drop packets until the client is disconnected (default value)

frequency (integer) - operating frequency of the AP (ignored for the client, which always scans through its scan list regardless of the value set in this field)frequency-mode (regulatory-domain | manual-tx-power | superchannel; default: regulatory-domain) - defines which frequency channels to allow

regulatory-domain - use the channels allowed in the selected country at the allowed transmit power (with the configured antenna-gain deducted) only. Also note that in this mode card will never be configured to higher power than allowed by the respective regulatory domain
manual-tx-power - use the channels allowed in the selected country only, but take transmit power from the tx-power settings
superchannel - only possible with the Superchannel license. In this mode all hardware supported channels and transmit power settings are allowed

hide-ssid (yes | no; default: no) - whether to hide ssid or not in the beacon frames:

yes - ssid is not included in the beacon frames. AP replies only to probe-requests with the given ssid
no - ssid is included in beacon frames. AP replies to probe-requests with the given ssid ant to 'broadcast ssid' (empty ssid)

hw-retries (integer; default: 15) - number of frame sending retries until the transmission is considered failed. Data rate is decreased upon failure, but if there is no lower rate, 3 sequential failures activate on-fail-retry-time transmission pause and the counter restarts. The frame is being retransmitted either until success or until client is disconnectedinterface-type (read-only: text) - adapter type and modelmac-address (MAC address) - Media Access Control (MAC) address of the interfacemaster-interface (name) - physical wireless interface name that will be used by Virtual Access Point (VAP) interfacemax-station-count (integer: 1..2007; default: 2007) - maximal number of clients allowed to connect to AP. Real life experiments (from our customers) show that 100 clients can work with one AP, using traffic shapingmode (alignment-only | ap-bridge | bridge | nstreme-dual-slave | station | station-pseudobridge | station-pseudobridge-clone | station-wds | wds-slave; default: station) - operating mode:

alignment-only - this mode is used for positioning antennas (to get the best direction)
ap-bridge - the interface is operating as an Access Point
bridge - the interface is operating as a bridge. This mode acts like ap-bridge with the only difference being it allows only one client
nstreme-dual-slave - the interface is used for nstreme-dual mode
station - the interface is operating as a wireless station (client)
station-pseudobridge - wireless station that can be put in bridge. MAC NAT is performed on all traffic sent over the wireless interface, so that it look like coming from the station's MAC address regardless of the actual sender (the standard does not allow station to send packets with different MAC address from its own). Reverse translation (when replies arrive from the AP to the pseudobridge station) is based on the ARP table. Non-IP protocols are being sent to the default MAC address (the last MAC address, which the station has received a non-IP packet from). That means that if there is more than one client that uses non-IP protocols (for example, PPPoE) behind the station, none of them will be able to work correctly
station-pseudobridge-clone - similar to the station-pseudobridge, but the station will clone MAC address of a particular device (set in the station-bridge-clone-mac property), i.e. it will change itsown address to the one of a different device. In case no address is set in the station-bridge-clone-mac property, the station postpones connecting to an AP until some packet, with the source MAC address different from any of the router itself, needs to be transmitted over that interface. It then connects to an AP with the MAC address of the device that have sent that packet
station-wds - the interface is working as a station, but can communicate with a WDS peer
wds-slave - the interface is working as it would work in ap-bridge mode, but it adapts to its WDS peer's frequency if it is changed

mtu (integer: 68..1600; default: 1500) - Maximum Transmission Unitname (name; default: wlanN) - assigned interface namenoise-floor-threshold (integer | default: -128..127; default: default) - noise strength in dBm below which the card will transmiton-fail-retry-time (time; default: 100ms) - time, after which we repeat to communicate with a wireless device, if a data transmission has failed 3 times on the lowest rateperiodic-calibration (default | disabled | enabled; default: default) - to ensure performance of chipset over temperature and environmental changes, the software performs periodic calibrationperiodic-calibration-interval (integer; default: 60) - interfal between periodic recalibrations, in secondspreamble-mode (both | long | short; default: both) - sets the synchronization field in a wireless packet

long - has a long synchronization field in a wireless packet (128 bits). Is compatible with 802.11 standard
short - has a short synchronization field in a wireless packet (56 bits). Is not compatible with 802.11 standard. With short preamble mode it is possible to get slightly higher data rates
both - supports both - short and long preamble

prism-cardtype (30mW | 100mW | 200mW) - specify the output of the Prism chipset based cardproprietary-extensions (pre-2.9.25 | post-2.9.25; default: post-2.9.25) - the method to insert additional information (MikroTik proprietary extensions) into the wireless frames. This option is needed to workaround incompatibility between the old (pre-2.9.25) method and new Intel Centrino PCI-Express cards

pre-2.9.25 - include extensions in the form accepted by older RouterOS versions. This will include the new format as well, so this mode is compatiblewith all RouterOS versions. This mode is incompatible with wireless clients built on the new Centrino wireless chipset and may as well be incompatible with some other stations

radio-name (text) - descriptive name of the card. Only for MikroTik devicesrate-set (default | configured) - which rate set to use:

default - basic and supported-rates settings are not used, instead default values are used
configured - basic and supported-rates settings are used as configured

scan-list (multiple choice: integer | default; default: default) - the list of channels to scan

default - represents all frequencies, allowed by the regulatory domain (in the respective country). If no country is set, these frequencies are used - for 2.4GHz mode: 2412, 2417, 2422, 2427, 2432, 2437, 2442, 2447, 2452, 2457, 2462; for 2.4GHz-g-turbo mode: 2437; for 5GHz mode: 5180, 5200, 5220, 5240, 5260, 5280, 5300, 5320, 5745, 5765, 5785, 5805, 5825; for 5GHz-turbo: 5210, 5250, 5290, 5760, 5800

security-profile (text; default: default) - which security profile to use. Define security profiles under /interface wireless security-profiles where you can setup WPA or WEP wireless security, for further details, see the Security Profiles section of this manualssid (text; default: MikroTik) - Service Set Identifier. Used to separate wireless networkssupported-rates-a/g (multiple choice: 6Mbps, 9Mbps, 12Mbps, 18Mbps, 24Mbps, 36Mbps, 48Mbps, 54Mbps) - rates to be supported in 802.11a or 802.11g standardsupported-rates-b (multiple choice: 1Mbps, 2Mbps, 5.5Mbps, 11Mbps) - rates to be supported in 802.11b standardtx-power (integer: -30..30; default: 17) - manually sets the transmit power of the card (in dBm), if tx-power-mode is set to card rates or all-rates-fixed (see tx-power-mode description below)tx-power-mode (all-rates-fixed | card-rates | default | manual-table; default: default) - choose the transmit power mode for the card:

all-rates-fixed - use one transmit power value for all rates, as configured in tx-power
card-rates - use transmit power, that for different rates is calculated according the cards transmit power algorithm, which as an argument takes tx-power value
default - use the default tx-power
manual-table - use the transmit powers as defined in /interface wireless manual-tx-power-table

update-stats-interval (time) - how often to update (request from the clients) signal strength and ccq values in /interface wireless registration-tablewds-cost-range (integer; default: 50-150) - range, within which the bridge port cost of the WDS links are adjusted. The calculations are based on the p-throughput value of the respective WDS interface, which represents estimated approimate rhtoughput on the interface, which is mapped on the wds-cost-range scale so that bigger p-throughput would correspond to numerically lower port cost. The cost is recalculated every 20 seconds or when the p-throughput changes more than by 10% since the last recalculationwds-default-bridge (name; default: none) - the default bridge for WDS interface. If you use dynamic WDS then it is very useful in cases when wds connection is reset - the newly created dynamic WDS interface will be put in this bridgewds-default-cost (integer; default: 100) - default bridge port cost of the WDS linkswds-ignore-ssid (yes | no; default: no) - if set to 'yes', the AP will create WDS links with any other AP in this frequency. If set to 'no' the ssid values must match on both APswds-mode (disabled | dynamic | static) - WDS mode:

disabled - WDS interfaces are disabled
dynamic - WDS interfaces are created 'on the fly'
static - WDS interfaces are created manually

wmm-support (disabled | enabled | required) - whether to allow (or require) peer to use WMM extensions to provide basic quality of service

Notes

The IEEE 802.11 standard limitation makes it impossible for wireless cards in station mode to work as expected when bridged. That means that if you need to create a bridge, you should not use station mode on that machine. In case you need a bridge on a wireless station, use station-wds mode (may only be used in the AP supports WDS). Bridging on the AP side works fine.

It is strongly suggested to leave basic rates at the lowest setting possible.

Using compression, the AP can serve approximately 50 clients with compression enabled!

Compression is supported only by Atheros wireless cards.

If disable-running-check value is set to no, the router determines whether the network interface is up and running - in order to show flag R for AP, one or more clients have to be registered to it, for station, it should be connected to an AP. If the interface does not appear as running (R), its route in the routing table is shown as invalid! If set to yes, the interface will always be shown as running.

On Atheros-based cards, encryption (WEP, WPA, etc.) does not work when compression is enabled.

The tx-power default setting is the maximum tx-power that the card can use. If you want to use larger tx-rates, you are able to set them, but do it at your own risk! Usually, you can use this parameter to reduce the tx-power.

In general tx-power controlling properties should be left at the default settings. Changing the default setting may help with some cards in some situations, but without testing, the most common result is degradation of range and throughput. Some of the problems that may occur are: (1) overheating of the power amplifier chip and the card which will cause lower efficiency and more data errors; (2) overdriving the amplifier which will cause more data errors; (3) excessive power usage for the card and this may overload the 3.3V power supply of the board that the card is located on resulting in voltage drop and reboot or excessive temperatures for the board.

For different versions of Atheros chipset there are different value range of ack-timeout property:

 

Chipset version 5ghz 5ghz-turbo 2ghz-b 2ghz-g
default max default max default max default max
5000 (5.2GHz only) 30 204 22 102 N/A N/A N/A N/A
5211 (802.11a/b) 30 409 22 204 109 409 N/A N/A
5212 (802.11a/b/g) 25 409 22 204 30 409 52 409

If the wireless interfaces are put in nstreme-dual-slave mode, all configuration will take place in /interface wireless nstreme-dual submenu, described further on in this manual. In that case, configuration made in this submenu will be partially ignored. WDS cannot be used together with the Nstreme-dual.

Some options are not shown by default - use print advanced in the console or press the "Advanced Mode" button in Winbox to see all the parameters

Interface Monitor

Command name: /interface wireless monitor [interface name]

Description

With this command you can monitor your link information. It is very useful if you have established a wireless link and want to monitor its status.

Property Description

802.1x-port-enabled (read-only: yes | no) - (on station only) whether the data exchange is allowed with the AP (i.e., whether 802.1x authentication is completed, if needed). Compare authenticated-clients and registered-clientsauthenticated-clients (read-only: integer) - clients that have successfully completed 802.11 authentication process and have associated with the AP. Normally it is possible to exchange data with client right after this step, however WPA/WPA2 needs additional 802.1x authentication and dynamic key exchange procedures that start only after this stage (see registered-clients). For a wireless station this property relates to its APband - operating bandbssid (read-only: MAC address) - (on station only) MAC address of the APcompression (read-only: yes | no) - (on station only) whether data compression is enabled for this interfacecurrent-ack-timeout (read-only: integer) - current value of ack-timeoutcurrent-tx-powers (read-only: text) - current transmit power values for every rate supported by the linkframing-mode (read-only: text) - (on station only) current framing modefrequency (read-only: integer) - operating frequencylast-ip (read-only: IP address) - (on station only) source IP address found in the last IP packet received from the APnoise-floor (read-only: text) - (on station only) received current noise levelnotify-external-fdb (read-only: yes | no) - whether forwarding database is to be generated from the link's registration table to add known hosts in the local bridge host table (i.e., the associated bridge port is configured to request this information - its respective external-fdb property is set to auto or yes)nstreme (read-only: yes | no) - whether nstreme protocol is used for this linkoverall-tx-ccq (read-only: integer) - overall link CCQ, for transmitting to the wireless infrastructure, not to aome particular peersp-throughput (read-only: integer) - (on station only) estimated approximate throughput that is expected on the given link, by taking into account the effective transmit rate and hardware retries. Calculated once in 5 secondsradio-name (read-only: text) - (on station only) radio nameregistered-clients (read-only: integer) - (on AP only) number of fully authenticated clients, that have completed not only 802.11 authentication procedures (as specified in the authenticated-clients propery), but also 802.1x ones.

Notes

Most values reported in station mode but absent for AP, are available in the registration table for particular stations connected to the AP.

Nstreme Settings

Submenu level: /interface wireless nstreme

Description

You can switch a wireless card to the nstreme mode. In that case the card will work only with nstreme clients.

Property Description

disable-csma (yes | no; default: no) - disable CSMA/CA when polling is used (better performance)enable-nstreme (yes | no; default: no) - whether to switch the card into the nstreme modeenable-polling (yes | no; default: yes) - whether to use polling for clientsframer-limit (integer; default: 3200) - maximal frame sizeframer-policy (none | best-fit | exact-size | dynamic-size; default: none) - the method how to combine frames. A number of frames may be combined into a bigger one to reduce the amount of protocol overhead (and thus increase speed). The card is not waiting for frames, but in case a number of packets are queued for transmitting, they can be combined. There are several methods of framing:

none - do nothing special, do not combine packets (framing is disabled)
best-fit - put as much packets as possible in one frame, until the framer-limit limit is met, but do not fragment packets
exact-size - put as much packets as possible in one frame, until the framer-limit limit is met, even if fragmentation will be needed (best performance)
dynamic-size - choose the best frame size dynamically

name (name) - reference name of the interface

Notes

The settings here (except for enabling nstreme) are relevant only on Access Point, they are ignored for client devices! The client automatically adapts to the AP settings.

WDS for Nstreme protocol requires using station-wds mode on one of the peers. Configurations with WDS between AP modes (bridge and ap-bridge) will not work.

Example

To enable the nstreme protocol on the wlan1 radio with exact-size framing:

[admin@MikroTik] interface wireless nstreme> print
 0 name="wlan1" enable-nstreme=no enable-polling=yes disable-csma=no
   framer-policy=none framer-limit=3200
[admin@MikroTik] interface wireless nstreme> set wlan1 enable-nstreme=yes \
\... framer-policy=exact-size
      

Nstreme2 Group Settings

Submenu level: /interface wireless nstreme-dual

Description

Two radios in nstreme-dual-slave mode can be grouped together to make nstreme2 Point-to-Point connection. To put wireless interfaces into a nstreme2 group, you should set their mode to nstreme-dual-slave. Many parameters from /interface wireless menu are ignored, using the nstreme2, except:

  • frequency-mode

Notes

WDS cannot be used on Nstreme-dual links.

The difference between tx-freq and rx-freq should be about 200MHz (more is recommended) because of the interference that may occur!

You can use different bands for rx and tx links. For example, transmit in 2.4ghz-g-turbo and receive data, using 2.4ghz-b band.

Example

To enable the nstreme2 protocol on a router:

  1. Having two Atheros based cards which are not used for anything else, to group them into a nstreme interface, switch both of them into nstreme-dual-slave mode:

    [admin@MikroTik] interface wireless> set 0,1 mode=nstreme-dual-slave
              
  2. Then add nstreme2 interface with exact-size framing:

    [admin@MikroTik] interface wireless nstreme-dual> add \
    \... framer-policy=exact-size
              
  3. Configure which card will be receiving and which - transmitting and specify remote receiver card's MAC address:

Connect List

Submenu level: /interface wireless connect-list

Description

The Connect List is a list of rules (order is important), that determine to which AP the station should connect to.

At first, the station is searching for APs all frequencies (from scan-list) in the respective band and makes a list of Access Points. If the ssid is set under /interface wireless, the router removes all Access Points from its AP list which do not have such ssid

If a rule is matched and the parameter connect is set to yes, the station will connect to this AP. If the parameter says connect=no or the rule is not matched, we jump to the next rule.

If we have gone through all rules and haven't connected to any AP, yet. The router chooses an AP with the best signal and ssid that is set under /interface wireless.

In case when the station has not connected to any AP, this process repeats from beginning.

Property Description

area-prefix (text) - a string that indicates the beginning from the area string of the AP. If the AP's area begins with area-prefix, then this parameter returns trueconnect (yes | no) - whether to connect to AP that matches this ruleinterface (name) - name of the wireless interfacemac-address (MAC address) - MAC address of the AP. If set to 00:00:00:00:00:00, all APs are acceptedsecurity-profile (name; default: none) - name of the security profile, used to connect to the AP. If none, then those security profile is used which is configured for the respective interfacesignal-range (integer) - signal strength range in dBm. Rule is matched, if the signal from AP is within this rangessid (text) - the ssid of the AP. If none set, all ssid's are accepted. Different ssids will be meaningful, if the ssid for the respective interface is set to ""

Access List

Submenu level: /interface wireless access-list

Description

The access list is used by the Access Point to restrict associations of clients. This list contains MAC addresses of clients and determines what action to take when client attempts to connect. Also, the forwarding of frames sent by the client is controlled. Note that is is an ordered list (i.e., checked from top to bottom).

The association procedure is as follows: when a new client wants to associate to the AP that is configured on interface wlanN, an entry with client's MAC address and interface wlanN is looked up sequentially from top to bottom in the access-list. If such entry is found, action specified in the access list is performed, else default-authentication and default-forwarding arguments of interface wlanN are taken.

Property Description

ap-tx-limit (integer; default: 0) - limits data rate for this wireless client (in bps)

0 - no limits

authentication (yes | no; default: yes) - whether to accept or to reject this client when it tries to connectclient-tx-limit (integer; default: 0) - limits this client's transmit data rate (in bps). Works only if the client is also a MikroTik Router

0 - no limits

forwarding (yes | no; default: yes) - whether to forward the client's frames to other wireless clientsinterface (name) - name of the respective interfacemac-address (MAC address) - MAC address of the client (can be 00:00:00:00:00:00 for any client)private-algo (104bit-wep | 40bit-wep | none) - which encryption algorithm to useprivate-key (text; default: "") - private key of the client. Used for private-algo private-pre-shared-key (text) - private preshared key for that station (in case any of the PSK authentication methods were used)signal-range (integer) - signal strength range in dBm. Rule is matched, if the signal from AP is within this rangetime (time) - rule is only matched during the specified period of time

Notes

If you have default authentication action for the interface set to yes, you can disallow this node to register at the AP's interface wlanN by setting authentication=no for it. Thus, all nodes except this one will be able to register to the interface wlanN.

If you have default authentication action for the interface set to no, you can allow this node to register at the AP's interface wlanN by setting authentication=yes for it. Thus, only the specified nodes will be able to register to the interface wlanN.

Example

To allow authentication and forwarding for the client 00:01:24:70:3A:BB from the wlan1 interface using WEP 40bit algorithm with the key 1234567890:

[admin@MikroTik] interface wireless access-list> add mac-address= \

Virtual Access Point Interface

Submenu level: /interface wireless

Description

Virtual Access Point (VAP) interface is used to have an additional AP. You can create a new AP with different ssid and mac-address. It can be compared with a VLAN where the ssid from VAP is the VLAN tag and the hardware interface is the VLAN switch.

You can add up to 128 VAP interfaces for each hardware interface.

RouterOS supports VAP feature for Atheros AR5212 and newer.

Property Description

area (text; default: "") - string value that is used to describe an Access Point. Connect List on the Client's side comparing this string value with area-prefix string value makes decision whether allow a Client connect to the AP. If area-prefix match the entire area string or only the beginning of it the Client is allowed to connect to the AParp (disabled | enabled | proxy-arp | reply-only) - ARP modedefault-ap-tx-limit (integer; default: 0) - limits data rate for each wireless client (in bps)

0 - no limits

default-authentication (yes | no; default: yes) - whether to accept or reject a client that wants to associate, but is not in the access-listdefault-client-tx-limit (integer; default: 0) - limits each client's transmit data rate (in bps). Works only if the client is also a MikroTik Router

0 - no limits

default-forwarding (yes | no; default: yes) - whether to forward frames to other AP clients or notdisable-running-check (yes | no; default: no) - disable running check. For 'broken' cards it is a good idea to set this value to 'yes'disabled (yes | no; default: yes) - whether to disable the interface or nothide-ssid (yes | no; default: no) - whether to hide ssid or not in the beacon frames:

yes - ssid is not included in the beacon frames. AP replies only to probe-requests with the given ssid
no - ssid is included in beacon frames. AP replies to probe-requests with the given ssid and to 'broadcast ssid'

mac-address (MAC address; default: 02:00:00:AA:00:00) - MAC address of VAP. You can define your own value for mac-addressmaster-interface (name) - hardware interface to use for VAPmax-station-count (integer; default: 2007) - number of clients that can connect to this AP simultaneouslymtu (integer: 68..1600; default: 1500) - Maximum Transmission Unitname (name; default: wlanN) - interface nameproprietary-extensions (pre-2.9.25 | post-2.9.25; default: post-2.9.25) - the method to insert additional information (MikroTik proprietary extensions) into the wireless frames. This option is needed to workaround incompatibility between the old (pre-2.9.25) method and new Intel Centrino PCI-Express cards

pre-2.9.25 - include extensions in the form accepted by older RouterOS versions. This will include the new format as well, so this mode is compatiblewith all RouterOS versions. This mode is incompatible with wireless clients built on the new Centrino wireless chipset and may as well be incompatible with some other stations

security-profile (text; default: default) - which security profile to use. Define security profiles under /interface wireless security-profiles where you can setup WPA or WEP wireless security, for further details, see the Security Profiles section of this manualssid (text; default: MikroTik) - the service set identifierupdate-stats-interval (time) - how often to update (request from the clients) signal strength and ccq values in /interface wireless registration-tablewds-cost-range (integer; default: 50-150) - range, within which the bridge port cost of the WDS links are adjusted. The calculations are based on the p-throughput value of the respective WDS interface, which represents estimated approimate rhtoughput on the interface, which is mapped on the wds-cost-range scale so that bigger p-throughput would correspond to numerically lower port cost. The cost is recalculated every 20 seconds or when the p-throughput changes more than by 10% since the last recalculationwds-default-bridge (name; default: none) - the default bridge for WDS interface. If you use dynamic WDS then it is very useful in cases when wds connection is reset - the newly created dynamic WDS interface will be put in this bridgewds-default-cost (integer; default: 100) - default bridge port cost of the WDS linkswds-ignore-ssid (yes | no; default: no) - if set to 'yes', the AP will create WDS links with any other AP in this frequency. If set to 'no' the ssid values must match on both APswds-mode (disabled | dynamic | static) - WDS mode:

disabled - WDS interfaces are disabled
dynamic - WDS interfaces are created 'on the fly'
static - WDS interfaces are created manually

wmm-support (disabled | enabled | required) - whether to allow (or require) peer to use WMM extensions to provide basic quality of service

Notes

The VAP MAC address is set by default to the same address as the physical interface has, with the second bit of the first byte set (i.e., the MAC address would start with 02). If that address is already used by some other wireless or VAP interface, it is increased by 1 until a free spot is found. When manually assigning MAC address, keep in mind that it should have the first bit of the first byte unset (so it should not be like 01, or A3). Note also that it is recommended to keep the MAC adress of VAP as similar (in terms of bit values) to the MAC address of the physical interface it is put onto, as possible, because the more different the addresses are, the more it affects performance.

WDS Interface Configuration

Submenu level: /interface wireless wds

Description

WDS (Wireless Distribution System) allows packets to pass from one wireless AP (Access Point) to another, just as if the APs were ports on a wired Ethernet switch. APs must use the same standard (802.11a, 802.11b or 802.11g) and work on the same frequencies in order to connect to each other.

There are two possibilities to create a WDS interface:

  • dynamic - is created 'on the fly' and appers under wds menu as a dynamic interface
  • static - is created manually

Property Description

arp (disabled | enabled | proxy-arp | reply-only; default: enabled) - Address Resolution Protocol

disabled - the interface will not use ARP
enabled - the interface will use ARP
proxy-arp - the interface will use the ARP proxy feature
reply-only - the interface will only reply to the requests originated to its own IP addresses. Neighbour MAC addresses will be resolved using /ip arp statically set table only

disable-running-check (yes | no; default: no) - disable running check. For 'broken' wireless cards it is a good idea to set this value to 'yes'mac-address (read-only: MAC address; default: 00:00:00:00:00:00) - MAC address of the master-interface. Specifying master-interface, this value will be set automaticallymaster-interface (name) - wireless interface which will be used by WDSmtu (integer: 0..65336; default: 1500) - Maximum Transmission Unitname (name; default: wdsN) - WDS interface namewds-address (MAC address) - MAC address of the remote WDS host

Notes

When the link between WDS devices, using wds-mode=dynamic, goes down, the dynamic WDS interfaces disappear and if there are any IP addresses set on this interface, their 'interface' setting will change to (unknown). When the link comes up again, the 'interface' value will not change - it will remain as (unknown). That's why it is not recommended to add IP addresses to dynamic WDS interfaces.

If you want to use dynamic WDS in a bridge, set the wds-default-bridge value to desired bridge interface name. When the link will go down and then it comes up, the dynamic WDS interface will be put in the specified bridge automatically.

As the routers which are in WDS mode have to communicate at equal frequencies, it is not recommended to use WDS and DFS simultaneously - it is most probable that these routers will not connect to each other.

WDS significantly faster than EoIP (up to 10-20% on RouterBOARD 500 systems), so it is recommended to use WDS whenever possible.

Example

[admin@MikroTik] interface wireless wds> add master-interface=wlan1 \
\... wds-address=00:0B:6B:30:2B:27 disabled=no
[admin@MikroTik] interface wireless wds> print

Align

Submenu level: /interface wireless align

Description

This feature is created to position wireless links. The align submenu describes properties which are used if /interface wireless mode is set to alignment-only. In this mode the interface 'listens' to those packets which are sent to it from other devices working on the same channel. The interface also can send special packets which contains information about its parameters.

Property Description

active-mode (yes | no; default: yes) - whether the interface will receive and transmit 'alignment' packets or it will only receive themaudio-max (integer; default: -20) - signal-strength at which audio (beeper) frequency will be the highestaudio-min (integer; default: -100) - signal-strength at which audio (beeper) frequency will be the lowestaudio-monitor (MAC address; default: 00:00:00:00:00:00) - MAC address of the remote host which will be 'listened'filter-mac (MAC address; default: 00:00:00:00:00:00) - in case if you want to receive packets from only one remote host, you should specify here its MAC addressframe-size (integer: 200..1500; default: 300) - size of 'alignment' packets that will be transmittedframes-per-second (integer: 1..100; default: 25) - number of frames that will be sent per second (in active-mode)receive-all (yes | no; default: no) - whether the interface gathers packets about other 802.11 standard packets or it will gather only 'alignment' packetsssid-all (yes | no; default: no) - whether you want to accept packets from hosts with other ssid than yours

Command Description

test-audio (integer) - test the beeper for 10 seconds

Notes

If you are using the command /interface wireless align monitor then it will automatically change the wireless interface's mode from station, bridge or ap-bridge to alignment-only.

Example

[admin@MikroTik] interface wireless align> print
           frame-size: 300
          active-mode: yes

Manual Transmit Power Table

Submenu level: /interface wireless manual-tx-power-table

Description

In this submenu you can define signal strength for each rate. You should be aware that you can damage your wireless card if you set higher output power than it is allowed. Note that the values in this table are set in dBm! NOT in mW! Therefore this table is used mainly to reduce the transmit power of the card.

Property Description

manual-tx-powers (text) - define tx-power in dBm for each rate, separate by commas

Example

To set the following transmit powers at each rates: 1Mbps@10dBm, 2Mbps@10dBm, 5.5Mbps@9dBm, 11Mbps@7dBm, do the following:

[admin@MikroTik] interface wireless manual-tx-power-table> print

Network Scan

Command name: /interface wireless scan interface_name

Description

This is a feature that allows you to scan all avaliable wireless networks. While scanning, the card unregisters itself from the access point (in station mode), or unregisters all clients (in bridge or ap-bridge mode). Thus, network connections are lost while scanning.

Property Description

Security Profiles

Submenu level: /interface wireless security-profiles

Description

This section provides WEP (Wired Equivalent Privacy) and WPA/WPA2 (Wi-Fi Protected Access) functions to wireless interfaces.

WPA

The Wi-Fi Protected Access is a combination of 802.1X, EAP, MIC, TKIP and AES. This is a easy to configure and secure wireless mechanism. It has been later updated to version 2, to provide greater security.

Pairwise master key caching for EAP authentification is supported for WPA2. This means that disconnected client can connect without repeated EAP authentication if keys are still valid (changed to interface or security profile configuration, restart, or Session-Timeout in case of RADIUS authentication).

WEP

The Wired Equivalent Privacy encrypts data only between 802.11 devices, using static keys. It is not considered a very secure wireless data encryption mechanism, though it is better than no encryption at all.

The configuration of WEP is quite simple, using MikroTik RouterOS security profiles.

Property Description

authentication-types (multiple choice: wpa-psk | wpa2-psk | wpa-eap | wpa2-eap; default: "") - the list of accepted authentication types. APs will advertise the listed types. Stations will choose the AP, which supports the "best" type from the list (WPA2 is always preferred to WPA1; EAP is preferred to PSK)eap-methods (multiple choice: eap-tls | passthrough) - the ordered list of EAP methods. APs will to propose to the stations one by one (if first method listed is rejected, the next one is tried). Stations will accept first proposed method that will be on the list

eap-tls - Use TLS certificates for authentication
passthrough - relay the authentication process to the RADIUS server (not used by the stations)

group-ciphers (multiple choice: tkip | aes-ccm) - a set of ciphers used to encrypt frames sent to all wireless station (broadcast transfers) in the order of preference

tkip - Temporal Key Integrity Protocol - encryption protocol, compatible with lagacy WEP equipment, but enhanced to correct some of WEP flaws
aes-ccm - more secure WPA encryption protocol, based on the reliable AES (Advanced Encryption Standard). Networks free of WEP legacy should use only this

group-key-update (time; default: 5m) - how often to update group key. This parameter is used only if the wireless card is configured as an Access Pointinterim-update (time) - default update interval for RADIUS accounting, if RADIUS server has not provided different valuemode (none | static-keys-optional | static-keys-required | dynamic-keys; default: none) - security mode:

none - do not encrypt packets and do not accept encrypted packets
static-keys-optional - if there is a static-sta-private-key set, use it. Otherwise, if the interface is set in an AP mode, do not use encryption, if the the interface is in station mode, use encryption if the static-transmit-key is set
static-keys-required - encrypt all packets and accept only encrypted packets
dynamic-keys - generate encryptioon keys dynamically

name (name) - descriptive name for the security profileradius-eap-accounting (yes | no; default: no) - use RADUIS accounting if EAP authentication is usedradius-mac-accounting (yes | no; default: no) - use RADIUS accounting, providing MAC address as usernameradius-mac-authentication (no | yes; default: no) - whether to use RADIUS server for MAC authenticationradius-mac-caching (time; default: disabled) - how long the RADIUS authentication reply for MAC address authentication if considered valid (and thus can be cached for faster reauthentication)radius-mac-format (text; default: XX:XX:XX:XX:XX:XX) - MAC address format to use for communication with RADIUS serverradius-mac-mode (as-username | as-username-and-password; default: as-username) - whether to use MAC address as username only or ad both username and password for RADIUS authenticationstatic-algo-0 (none | 40bit-wep | 104bit-wep | aes-ccm | tkip; default: none) - which encryption algorithm to use:

none - do not use encryption and do not accept encrypted packets
40bit-wep - use the 40bit encryption (also known as 64bit-wep) and accept only these packets
104bit-wep - use the 104bit encryption (also known as 128bit-wep) and accept only these packets
aes-ccm - use the AES-CCM (Advanced Encryption Standard in Counter with CBC-MAC) encryption algorithm and accept only these packets
tkip - use the TKIP (Temporal Key Integrity Protocol) and accept only these packets

static-algo-1 (none | 40bit-wep | 104bit-wep | aes-ccm | tkip; default: none) - which encryption algorithm to use:

none - do not use encryption and do not accept encrypted packets
40bit-wep - use the 40bit encryption (also known as 64bit-wep) and accept only these packets

static-key-0 (text) - hexadecimal key which will be used to encrypt packets with the 40bit-wep or 104bit-wep algorithm (algo-0). If AES-CCM is used, the key must consist of even number of characters and must be at least 32 characters long. For TKIP, the key must be at least 64 characters long and also must consist of even number characters static-key-1 (text) - hexadecimal key which will be used to encrypt packets with the 40bit-wep or 104bit-wep algorithm (algo-1). If AES-CCM is used, the key must consist of even number of characters and must be at least 32 characters long. For TKIP, the key must be at least 64 characters long and also must consist of even number characters static-key-2 (text) - hexadecimal key which will be used to encrypt packets with the 40bit-wep or 104bit-wep algorithm (algo-2). If AES-CCM is used, the key must consist of even number of characters and must be at least 32 characters long. For TKIP, the key must be at least 64 characters long and also must consist of even number characters static-key-3 (text) - hexadecimal key which will be used to encrypt packets with the 40bit-wep or 104bit-wep algorithm (algo-3). If AES-CCM is used, the key must consist of even number of characters and must be at least 32 characters long. For TKIP, the key must be at least 64 characters long and also must consist of even number characters static-sta-private-algo (none | 40bit-wep | 104bit-wep | aes-ccm | tkip) - algorithm to use if the static-sta-private-key is set. Used to commumicate between 2 devicesstatic-sta-private-key (text) - if this key is set in station mode, use this key for encryption. In AP mode you have to specify static-private keys in the access-list or use the Radius server using radius-mac-authentication. Used to commumicate between 2 devicesstatic-transmit-key (static-key-0 | static-key-1 | static-key-2 | static-key-3; default: static-key-0) - which key to use for broadcast packets. Used in AP modesupplicant-identity (text; default: MikroTik) - EAP supplicant identity to use for RADIUS EAP authenticationtls-certificate (name) - select the certificate for this device from the list of imported certificatestls-mode (no-certificates | dont-verify-certificate | verify-certificate; default: no-certificates) - TLS certificate mode

no-certificates - certificates are negotiated dynamically using anonymous Diffie-Hellman MODP 2048 bit algorithm
dont-verify-certificate - require a certificate, but do not chack, if it has been signed by the available CA certificate
verify-certificate - require a certificate and verify that it has been signed by the available CA certificate

unicast-ciphers (multiple choice: tkip | aes-ccm) - a set of ciphers used to encrypt frames sent to individual wireless station (unicast transfers) in the order of preference

tkip - Temporal Key Integrity Protocol - encryption protocol, compatible with lagacy WEP equipment, but enhanced to correct some of WEP flaws
aes-ccm - more secure WPA encryption protocol, based on the reliable AES (Advanced Encryption Standard). Networks free of WEP legacy should use only this

wpa-pre-shared-key (text; default: "") - string, which is used as the WPA Pre Shared Key. It must be the same on AP and station to communicatewpa2-pre-shared-key (text; default: "") - string, which is used as the WPA2 Pre Shared Key. It must be the same on AP and station to communicate

Notes

The keys used for encryption are in hexadecimal form. If you use 40bit-wep, the key has to be 10 characters long, if you use 104bit-wep, the key has to be 26 characters long.

Prism card doesn't report that the use of WEP is required for all data type frames, which means that some clients will not see that access point uses encryption and will not be able to connect to such AP. This is a Prism hardware problem and can not be fixed. Use Atheros-based cards (instead of Prism) on APs if you want to provide WEP in your wireless network.

Wireless encryption cannot work together with wireless compression.
