	RouterOS v3 Configuration and User Guide

address to the one of a different device. In case no address is set in the station-bridge-clone-macproperty, 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 Unit

name (name; default: wlanN) - assigned interface name

noise-floor-threshold(integer default: -128..127; default: default) - noise strength in dBm below which the card will transmit

on-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 rate

periodic-calibration(default disabled enabled; default: default) - to ensure performance of chipset over temperature and environmental changes, the software performs periodic calibration periodic-calibration-interval(integer; default: 60) - interfal between periodic recalibrations, in seconds preamble-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 card proprietary-extensions(pre-2.9.25 post-2.9.25; default: post-2.9.25) - the method to insert additional information (RouterOS 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 RouterOS devices rate-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 manual

ssid (text; default: AT-WR4560) - Service Set Identifier. Used to separate wireless networks

supported-rates-a/g(multiple choice: 6Mbps, 9Mbps, 12Mbps, 18Mbps, 24Mbps, 36Mbps, 48Mbps, 54Mbps) - rates to be supported in 802.11a or 802.11g standard

supported-rates-b(multiple choice: 1Mbps, 2Mbps, 5.5Mbps, 11Mbps) - rates to be supported in 802.11b standard

tx-power(integer: -30..30; default: 17) - manually sets the transmit power of the card (in dBm), if tx- power-modeis 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-table
