Basic settings

`master-interface`

Syntax: interface name
Description: Name of wireless interface that has virtual-ap capability.
Virtual AP interface will only work if master interface is in ap-bridge, bridge or wds-slave mode.
This property is only for virtual AP interfaces.

`mode`

Syntax: One of station, station-wds, ap-bridge, bridge, alignment-only, nstreme-dual-slave, wds-slave, station-pseudobridge or station-pseudobridge-clone
Default value: station
Description:

Station modes:

station - Basic station mode. Find and connect to acceptable AP.
station-wds - Same as station, but create WDS link with AP, using proprietary extension. AP configuration has to allow WDS links with this device. Note that this mode does not use entries in wds.
station-pseudobridge - Same as station, but additionally perform MAC address translation of all traffic. Allows interface to be bridged.
station-pseudobridge-clone - Same as station-pseudobridge, but use station-bridge-clone-mac address to connect to AP.

AP modes:

ap-bridge - Basic access point mode.
bridge - Same as ap-bridge, but limited to one associated client.
wds-slave - Same as ap-bridge, but scan for AP with the same ssid and establishes WDS link. If this link is lost or cannot be established, then continue scanning. If dfs-mode is radar-detect, then APs with enabled hide-ssid will not be found during scanning.

Special modes:

alignment-only - Put interface in a continuous transmit mode that is used for aiming remote antenna.
nstreme-dual-slave - allow this interface to be used in nstreme-dual setup.

MAC address translation in pseudobridge modes works by inspecting packets and building table of corresponding IP and MAC addresses. All packets are sent to AP with the MAC address used by pseudobridge, and MAC addresses of received packets are restored from the address translation table. There is single entry in address translation table for all non-IP packets, hence more than one host in the bridged network cannot reliably use non-IP protocols.
Virtual AP interfaces do not have this property, they follow the mode of their master interface.

`ssid`

Syntax: text, up to 32 characters long
Default value: value of system/identity
Description: SSID (service set identifier) is a name that identifies wireless network.

`frequency`

Syntax: Frequency value in MHz.
Description: Channel frequency on which AP will operate.
Allowed values depend on selected band, and are restricted by country setting and wireless card capabilities. This setting has no effect if interface is in any of station modes, or in 'wds-slave' mode, or if DFS is active.

`band`

Syntax: one of 2.4ghz-b, 5ghz, 5ghz-turbo, 2.4ghz-b/g, 2.4ghz-g-turbo, 5ghz-10mhz, 5ghz-5mhz, 2ghz-10mhz, 2ghz-5mhz, 5ghz-11n, 2ghz-11n, 2.4ghz-onlyg

`scan-list`

Syntax: comma separated list of frequencies and frequency ranges, or default
Description: The default value is all channels from selected band that are supported by card and allowed by the country and frequency-mode settings (this list can be seen in info). For default scan list in 5ghz band channels are taken with 20MHz step, in 5ghz-turbo band - with 40MHz step, for all other bands - with 5MHz step. If scan-list is specified manually, then all matching channels are taken.
Example: scan-list=default,5200-5245,2412-2427 This will use the default value of scan list for current band, and add to it supported frequencies from 5200-5245 or 2412-2427 range.

`antenna-mode`

Syntax:

one of these values:

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

`wds-mode`

Syntax: one of disabled, static, dynamic, static-mesh or dynamic-mesh
Description:

Controls how WDS links with other devices (APs and clients in station-wds mode) are established.

disabled does not allow WDS links.
static only allows WDS links that are manually configured in wds
dynamic also allows WDS links with devices that are not configured in wds, by creating required entries dynamically. Such dynamic WDS entries are removed automatically after the connection with the other AP is lost.

"-mesh" modes use different (better) method for establishing link between AP, that is not compatible with APs in non-mesh mode. This method avoids one-sided WDS links that are created only by one of the two APs. Such links cannot pass any data.
When AP or station is establishing WDS connection with another AP, it uses connect-list to check whether this connection is allowed. If station in station-wds mode is establishing connection with AP, AP uses access-list to check whether this connection is allowed.
If mode is station-wds, then this property has no effect.

`wds-default-bridge`

Syntax: none, or name of bridge interface
Description: When WDS link is established and status of the wds interface becomes 'running', it will be added as a bridge port to the bridge interface specified by this property. When WDS link is lost, wds interface is removed from the bridge.
If wds interface is already included in a bridge setup when WDS link becomes active, it will not be added to bridge specified by , and will

`wds-ignore-ssid`

Syntax: yes or no
Default value: no
Description: By default, WDS link between two APs can be created only when they work on the same frequency and have the same SSID value. If this property is set to yes, then SSID of the remote AP will not be checked. This property has no effect on connections from clients in station-wds mode. It also does not work if wds-mode is static-mesh or dynamic-mesh.

`default-authentication`

Syntax: yes or no
Default value: yes
Description: For AP mode, this is the value of authentication for clients that do not match any entry in the access-list. For station mode, this is the value of connect for APs that do not match any entry in the connect-list.

`default-forwarding`

Syntax: yes or no
Default value: yes
Description: This is the value of forwarding for clients that do not match any entry in the access-list.

`default-ap-tx-limit`

Description: This is the value of ap-tx-limit for clients that do not match any entry in the access-list.

`default-client-tx-limit`

Description: This is the value of client-tx-limit for clients that do not match any entry in the access-list.

`hide-ssid`

Syntax: yes or no
Default value: no

Description:

yes - AP does not include SSID the beacon frames, and does not reply to probe requests that have broadcast SSID.
no - AP includes SSID in the beacon frames, and replies to probe requests that have broadcast SSID.

This property has effect only in AP mode. Setting it to yes can remove this network from the list of wireless networks that are shown by some client software. Changing this setting does not improve security of the wireless network, because SSID is included in other frames sent by the AP.

`security-profile`

Syntax: name of profile from security-profiles

`compression`

Syntax: yes or no
Default value: no
Description: Setting this property to yes will allow use of the hardware compression. Wireless interface must have support for hardware compression. Connections with devices that do not use compression will still work.

`interface-type`

Syntax: virtual-AP, Prism, or Atheros model_name
Read-only property
Description: This specifies type of wireless interface. Some properties have meaning only for certain types of interfaces.

Advanced settings

`frequency-mode`

Syntax:

one of these values:

regulatory-domain - Limit available channels and maximum transmit power for each channel according to the value of country
manual-txpower - Same as above, but do not limit maximum transmit power.
superchannel - Allow all channels supported by the card.

Description: List of available channels for each band can be seen in info.

`country`

Syntax: either no_country_set, or name of regulatory domain
Description: Limits available bands, frequencies and maximum transmit power for each frequency. Also specifies default value of scan-list. Value no_country_set is an FCC compliant set of channels.

`antenna-gain`

Default value: 0
Description:
Antenna gain in dBi, used to calculate maximum transmit power according to country limitations.

`rate-set`

Syntax: default or configured

Description:

default - default basic and supported rate sets are used. Values from basic-rates and supported-rates parameters have no effect.
configured - use values from basic-rates and supported-rates parameters. Note that g mode bands use rates from both "rates-b" and "rates-a/g" properties.

`supported-rates-b`

Description:
List of supported rates, used for 2.4ghz-b, 2.4ghz-b/g and 2.4ghz-onlyg bands. Two devices will communicate only using rates that are supported by both devices. This property has effect only when value of rate-set is configured.

`supported-rates-a/g`

Description:
Similar to the above property, but used for 5ghz, 5ghz-10mhz, 5ghz-5mhz, 5ghz-turbo, 2.4ghz-b/g, 2.4ghz-onlyg, 2ghz-10mhz, 2ghz-5mhz and 2.4ghz-g-turbo bands.

basic-rates-b

Description:
List of basic rates, used for 2.4ghz-b, 2.4ghz-b/g and 2.4ghz-onlyg bands.
Client will connect to AP only if it supports all basic rates announced by the AP. AP will establish WDS link only if it supports all basic rates of the other AP. This property has effect only in AP modes, and when value of rate-set is 'configured'.

basic-rates-a/g

Default value: 2007
Description: Maximum number of associated clients. WDS links also count toward this limit.

ack-timeout

Syntax: 'indoors', 'dynamic', or value in microseconds
Description:
How long to wait for confirmation of unicast frames before considering transmission unsuccessful. Value 'dynamic' causes AP to detect and use smallest timeout that works with all connected clients. Acknowledgements are not used in Nstreme protocol.

tx-power

Syntax:

value in the -30..30 range

tx-power-mode

Syntax:

one of these values:

default -
all-rates-fixed -
card-rates -
manual-table -

dfs-mode

Syntax: one of 'none', 'no-radar-detect' and 'radar-detect'
Default value: none
Description:

Controls DFS (Dynamic Frequency Selection).

none - disables DFS.
no-radar-detect - Select channel from scan-list with the lowest number of detected networks. In 'wds-slave' mode this setting has no effect.
radar-detect - Select channel with the lowest number of detected networks and use it if no radar is detected on it for 60 seconds. Otherwise, select different channel. This setting may be required by the country regulations.

This property has effect only in AP mode.

wds-default-cost

Syntax: Number
Default value: 100
Description: Initial bridge port cost of the WDS links.

wds-cost-range

Syntax: Numeric range
Default value: 50-150
Description:
Bridge port cost of WDS links are automatically adjusted, depending on measured link throughput. Port cost is recalculated and adjusted every 5 seconds if it has changed by more than 10%, or if more than 20 seconds have passed since the last adjustment. Setting this property to '0' disables automatic cost adjustment. Automatic adjustment does not work for WDS links that are manually configured as a bridge port.

wmm-support

Syntax: 'disabled', 'enabled' or 'required'

disconnect-timeout

Syntax: time interval in the 0..15s range, in units of 10ms
Default value: 3s
Description:
This interval is measured from third sending failure on the lowest data rate. At this point 3 * (hw-retries + 1) frame transmits on the lowest data rate had failed. During disconnect-timeout packet transmission will be retried with on-fail-retry-time interval. If no frame can be transmitted successfully during diconnect-timeout, connection is closed, and this event is logged as "extensive data loss". Successful frame transmission resets this timer.

on-fail-retry-time

Syntax: time interval in the 10ms..1s range, in 10ms units
Default value: 100ms
Description: After third sending failure on the lowest data rate, wait for this long before retrying.

frame-lifetime

Syntax: time in hundredths of a second
Default value: 0
Description:
Discard frames that have been queued for sending longer than frame-lifetime. By default, when value of this property is 0, frames are discarded only after connection is closed.

preamble-mode

Syntax: one of 'long', 'short' or 'both'
Default value: both
Description: Short preamble mode is an option of 802.11b standard that reduces per-frame overhead.

On AP:

long - Do not use short preamble.
short - Announce short preamble capability. Do not accept connections from clients that do not have this capability.
both - Announce short preamble capability.

On station:

long - do not use short preamble.
short - do not connect to AP if it does not support short preamble.
both - Use short preamble if AP supports it.

allow-sharedkey

Syntax: 'yes' or 'no'
Default value: no
Description: 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).

station-bridge-clone-mac

Syntax: MAC address
Description: This property has effect only in the 'station-pseudobridge-clone' mode.
Use this MAC address when connection to AP. If this value is 00:00:00:00:00:00, station will initially use MAC address of the wireless interface. As soon as packet with MAC address of another device needs to be transmitted, station will reconnect to AP using that address.

hw-retries

Syntax: number 0..15
Default value: 15
Description:
Number of times sending frame is retried without considering it a transmission failure. Data rate is decreased upon failure and frame is sent again. Three sequential failures on lowest supported rate suspend transmission to this destination for the duration of on-fail-retry-time. After that, frame is sent again. The frame is being retransmitted until transmission success, or until client is disconnected after disconnect-timeout. Frame can be discarded during this time if frame-lifetime is exceeded.

Proprietary extensions

radio-name

Syntax: Text
Description: Descriptive name of the device, that is shown in registration table entries on the remote devices.
This is a proprietary extension.

area

Syntax: Text
Default value: empty
Description: Identifies group of wireless networks. This value is announced by AP, and can be matched in connect-list by area-prefix. This is a proprietary extension.

update-stats-interval

Syntax: 'disabled' or time interval in the 10s..5h range
Default value: disabled
Description: How often to request update of signals strength and ccq values from clients. Access to registration-table also triggers update of these values. This is proprietary extension.

proprietary-extensions

Syntax: 'pre-2.9.25' or 'post-2.9.25'
Default value: post-2.9.25
Description:

RouterOS includes proprietary information in an information element of management frames. This parameter controls how this information is included.

pre-2.9.25 - This is older method. It can interoperate with newer versions of RouterOS. This method is incompatible with some clients, for example, Centrino based ones.
post-2.9.25 - This uses standardized way of including vendor specific information, that is compatible with newer wireless clients.

Atheros specific

noise-floor-threshold

Syntax: 'default' or value in the -128..127 range
Description: This property is only effective for cards based on AR5211 chipset.

adaptive-noise-immunity

Syntax: 'yes' or 'no'
Default value: yes
Description: This property is only effective for cards based on Atheros chipset.

periodic-calibration

Syntax: one of 'default', 'enabled' or 'disabled'
Description: Setting 'default' enables periodic calibration if info default-periodic-calibration property is 'enabled'. Value of that property depends on the type of wireless card. This property is only effective for cards based on Atheros chipset.

periodic-calibration-interval

Syntax: value in range 1..10000
Default value: 60

-	<li>In station mode, if several remote access points are matched by connect list rules with <code>connect=yes</code> value, connection will be attempted with access point that is matched by rule higher in the connect-list.
-	<li>If no remote access points are matched by connect-list rules with <code>connect=yes</code> value, then value of <code>default-authentication</code> interface property determines whether station will attempt to connect to any access point. If <code>default-authentication=yes</code>, station will choose access point with best signal and compatible security.
-    </ul>

-<h3>Operation details</h3>
-<h4>RADIUS MAC authentication</h4>
-<br><strong>Note: </strong>
-<br>RAIDUS MAC authentication is used by access point for clients that are not found in the [[access-list]], similarly to the <var>default-authentication</var> property of the wireless interface. It controls whether client is allowed to proceed with authentication, or is rejected immediately.
-<br>When <var>radius-mac-authentication</var>=<i>yes</i>, access point queries RADIUS server by sending Access-Request with the following attributes:<ul>
-    <li>User-Name - Client MAC address. This is encoded as specified by the <var>radius-mac-format</var> setting. Default encoding is "XX:XX:XX:XX:XX:XX".
-    <li>Nas-Port-Id - <var>name</var> of wireless interface.
-    <li>User-Password - When <var>radius-mac-mode</var>=<i>as-username-and-password</i> this is set to the same value as User-Name. Otherwise this attribute is empty.
-    <li>Calling-Station-Id - Client MAC address, encoded as "XX-XX-XX-XX-XX-XX".
-    <li>Called-Station-Id - MAC address and SSID of the access point, encoded as "XX-XX-XX-XX-XX-XX:SSID" (minus separated pairs of MAC address digits, followed by colon, followed by SSID value).
-    <li>Acct-Session-Id - Added when <var>radius-mac-accounting</var>=<i>yes</i>.
-</ul>
-<br>When access point receives Access-Accept or Access-Reject response from the RADIUS server, it stores the response and either allows or rejects client. Access point uses following RADIUS attributes from the Access-Accept response:<ul>
-    <li>Ascend-Data-Rate
-    <li>Ascend-Xmit-Rate
-    <li>Mikrotik-Wireless-Forward - Same as [[access-list]] <var>forwarding</var>.
-    <li>Mikrotik-Wireless-Enc-Algo - Same as [[access-list]] <var>private-algo</var>.
-    <li>Mikrotik-Wireless-Enc-Key - Same as [[access-list]] <var>private-key</var>.
-    <li>Mikrotik-Wireless-Psk - Same as [[access-list]] <var>private-pre-shared-key</var>.
-    <li>Session-Timeout - Time, after which client will be disconnected.
-    <li>Acct-Interim-Interval - Overrides value of <var>interim-update</var>.
-    <li>Class - If present, value of this attribute is saved and included in Accounting-Request messages.
-</ul>
-<h5>Caching</h5>
-<br>Caching of RADIUS MAC authentication was added to support RADIUS authentication for clients that require from the access point very quick response to the association request. Such clients time out before response from RADIUS server is received. Access point caches authentication response for some time and can immediately reply to the repeated association request from the same client.
-<H4>RADIUS EAP pass-through authentication</H4>
-<br>When using WPA EAP authentication type, clients that have passed MAC authentication are required to perform EAP authentication before being authorized to pass data on wireless network. With pass-through EAP method the access point will relay authentication to RADIUS server, and use following attributes in the Access-Request RADIUS message: <ul>
-    <li>User-Name - EAP supplicant identity. This value is configured in the <var>supplicant-identity</var> property of the client security profile.
-    <li>Nas-Port-Id - <var>name</var> of wireless interface.
-    <li>Calling-Station-Id - Client MAC address, encoded as "XX-XX-XX-XX-XX-XX".
-    <li>Called-Station-Id - MAC address and SSID of the access point, encoded as "XX-XX-XX-XX-XX-XX:SSID" (pairs of MAC address digits separated by minus sign, followed by colon, followed by SSID value).
-    <li>Acct-Session-Id - Added when <var>radius-eap-accounting</var>=<i>yes</i>.
-    <li>Acct-Multi-Session-Id - MAC address of access point and client, and unique 8 byte value, that is shared for all accounting sessions that share single EAP authentication. Encoded as <i>AA-AA-AA-AA-AA-AA-CC-CC-CC-CC-CC-CC-XX-XX-XX-XX-XX-XX-XX-XX</i>.
-    <br>Added when <var>radius-eap-accounting</var>=<i>yes</i>.
-</ul>
-<br>Access point uses following RADIUS attributes from the Access-Accept server response:<ul>
-    <li>Class - If present, value of this attribute is saved and included in Accounting-Request messages.
-    <li>Session-Timeout - Time, after which client will be disconnected. Additionally, access point will remember authentication result, and if during this time client reconnects, it will be authorized immediately, without repeating EAP authentication.
-    <li>Acct-Interim-Interval - Overrides value of <var>interim-update</var>.
-</ul>
-<h4>Statically configured WEP keys</h4>
-Different algorithms require different length of keys:<ul>
-    <li><i>40bit-wep</i> - 10 hexadecimal digits (40 bits). If key is longer, only first 40 bits are used.
-    <li><i>104bit-wep</i> - 26 hexadecimal digits (104 bits). If key is longer, only first 104 bits are used.
-    <li><i>tkip</i> - At least 64 hexadecimal digits (256 bits).
-    <li><i>aes-ccm</i> - At least 32 hexadecimal digits (128 bits).
-</ul>
-Key must contain even number of hexadecimal digits.
-<h4>WDS security configuration</h4>
-<br>WDS links can use all available security features. However, they require careful configuration of security parameters.
-<br>It is possible to use one security profile for all clients, and different security profiles for WDS links. Security profile for WDS link is specified in [[connect-list]]. Access point always checks connect list before establishing WDS link with another access point, and used security settings from matching connect list entry. WDS link will work when each access point will have connect list entry that matches the other device, has <var>connect</var>=<i>yes</i> and specifies compatible <var>security-profile</var>.
-<h5>WDS and WPA/WPA2</h5>
-<br>If access point uses security profile with <var>mode</var>=<i>dynamic-keys</i>, then encryption will be used for all WDS links. Since WPA authentication and key exchange is not symmetrical, one of the access points will act as a client for the purpose of establishing secure connection. This is similar to how <i>static-mesh</i> and <i>dynamic-mesh</i> WDS modes work. Some problems, like single sided WDS link between two incorrectly configured access points that use non<i>-mesh</i> mode, is not possible if WPA encryption is enabled. However, non<i>-mesh</i> modes with WPA still have other issues (like constant reconnection attempts in case of configuration mismatch) that are solved by use of the <i>-mesh</i> WDS modes.
-<br>In general, WPA properties on both access points that establish WPA protected WDS link have to match. These properties are <var>authentication-types</var>, <var>unicast-ciphers</var>, <var>group-ciphers</var>. For non<i>-mesh</i> WDS mode these properties need to have the same values on both devices. In <i>mesh</i> WDS mode each access point has to support the other one as a client.
-<br>Theoretically it is possible to use RADIUS MAC authentication and other RADIUS services with WDS links. However, only one access point will interact with the RADIUS server, the other access point will behave as a client.
-<br>Implementation of <i>eap-tls</i> EAP method in RouterOS is particularly well suited for WDS link encryption. <var>tls-mode</var>=<i>no-certificates</i> requires no additional configuration, and provides very strong encryption.
-<h5>WDS and WEP</h5>
-<br><var>mode</var>, <var>static-sta-private-key</var> and <var>static-sta-private-algo</var> parameters in the security profile assigned to the WDS link need to have the same values on both access points that establish WDS link with WPA encryption.
-<h4>Security profile and access point matching in the connect list</h4>
-Client uses value of [[connect-list]] <var>security-profile</var> property to match only those access points that support necessary security.<ul>
-    <li><var>mode</var>=<i>static-keys-required</i> and <var>mode</var>=<i>static-keys-optional</i> matches only access points with the same <var>mode</var> in interface <var>security-profile</var>.
-    <li>If <var>mode</var>=<i>dynamic-keys</i>, then connect list entry matches if all of the <var>authentication-types</var>, <var>unicast-ciphers</var> and <var>group-ciphers</var> contain at least one value that is advertised by access point.
