38 AT-WR4500 Series - IEEE 802.11abgh Outdoor Wireless Routers
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-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 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-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-table
