• 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

...

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.

...

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.

...

• 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 - Conformance Testing Mode. Allow all channels supported by the card.

...

• yes - AP does not include SSID in 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.

...

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. Note: Currently IPv6 doesn't work over Pseudobridge

...

• disabled - disables the helper and sends multicast packets with multicast destination MAC addresses
• full - all multicast packet mac address are changed to unicast mac addresses prior sending them out
• default - default choice that currently is set to disabled. Value can be changed in future releases.

...

• on AP: distance to farthest client in km
• on station: no effect

...

...

• frame-priority - manual setting that can be tuned with Mangle rules.
• default - default setting where small packets receive priority for best latency

...

• 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.

...

• 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.

...

• 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, supported-rates, basic-mcs, mcs. Read more >>.

...

scan-list

...

Since RouterOS v6.0 with Winbox or Webfig, for inputting of multiple frequencies, add each frequency or range of frequencies into separate multiple scan-lists. Using a comma to separate frequencies is no longer supported in Winbox/Webfig since v6.0.

...

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.

...

• default - use values stored in the card
• card-rates - use transmit power as defined by tx-power setting
• all-rated-fixed - use same transmit power for all data rates. Can damage the card if transmit power is set above rated value of the card for used rate
• manual-table - define transmit power for each rate separately. Can damage the card if transmit power is set above rated value of the card for used rate.

...

Access to registration-table also triggers update of these values.

...

You can set MCS interval for each of Spatial Stream

• none - will not use selected Spatial Stream
• MCS 0-7 - client must support MCS-0 to MCS-7
• MCS 0-8 - client must support MCS-0 to MCS-8
• MCS 0-9 - client must support MCS-0 to MCS-9

...

You can set MCS interval for each of Spatial Stream

• none - will not use selected Spatial Stream
• MCS 0-7 - devices will advertise as supported MCS-0 to MCS-7
• MCS 0-8 - devices will advertise as supported MCS-0 to MCS-8
• MCS 0-9 - devices will advertise as supported MCS-0 to MCS-9

...

Setting this property to 0 disables automatic cost adjustment.

...

• 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.

...

• unspecified - protocol mode used on previous RouterOS versions (v3.x, v4.x). Nstreme is enabled by old enable-nstreme setting, Nv2 configuration is not possible.
• any : on AP - regular 802.11 Access Point or Nstreme Access Point; on station - selects Access Point without specific sequence, it could be changed by connect-list rules.
• nstreme - enables Nstreme protocol (the same as old enable-nstreme setting).
• nv2 - enables Nv2 protocol.
• nv2 nstreme : on AP - uses first wireless-protocol setting, always Nv2; on station - searches for Nv2 Access Point, then for Nstreme Access Point.
• nv2 nstreme 802.11 - on AP - uses first wireless-protocol setting, always Nv2; on station - searches for Nv2 Access Point, then for Nstreme Access Point, then for regular 802.11 Access Point.
