AT-WR4500 Series - IEEE 802.11abgh Outdoor Wireless Routers	37
RouterOS v3 Configuration and User Guide

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 running

disconnect-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-timehas 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-gaindeducted) 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-timetransmission pause and the counter restarts. The frame is being retransmitted either until success or until client is disconnected

interface-type(read-only: text) - adapter type and model

mac-address(MAC address) - Media Access Control (MAC) address of the interface master-interface(name) - physical wireless interface name that will be used by Virtual Access Point (VAP) interface

max-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 shaping

mode (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-bridgewith 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-macproperty), i.e. it will change itsown
