RouterOS v3 Configuration and User Guide

wds-cost-range(integer; default: 50-150) - range, within which the bridge port cost of the WDS links are adjusted. The calculations are based on the p-throughputvalue of the respective WDS interface, which represents estimated approimate rhtoughput on the interface, which is mapped on the wds-cost- range scale so that bigger p-throughputwould correspond to numerically lower port cost. The cost is recalculated every 20 seconds or when the p-throughputchanges more than by 10% since the last recalculation

wds-default-bridge(name; default: none) - the default bridge for WDS interface. If you use dynamic WDS then it is very useful in cases when wds connection is reset - the newly created dynamic WDS interface will be put in this bridge

wds-default-cost(integer; default: 100) - default bridge port cost of the WDS links

wds-ignore-ssid(yes no; default: no) - if set to 'yes', the AP will create WDS links with any other AP in this frequency. If set to 'no' the ssid values must match on both APs

wds-mode(disabled dynamic static) - WDS mode: disabled - WDS interfaces are disabled dynamic - WDS interfaces are created 'on the fly' static - WDS interfaces are created manually

wmm-support(disabled enabled required) - whether to allow (or require) peer to use WMM extensions to provide basic quality of service

The IEEE 802.11 standard limitation makes it impossible for wireless interfaces in station mode to work as expected when bridged. That means that if you need to create a bridge, you should not use station mode on that machine. In case you need a bridge on a wireless station, use station-wds mode (may only be used in the AP supports WDS). Bridging on the AP side works fine.

It is strongly suggested to leave basic rates at the lowest setting possible.

Using compression, the AP can serve approximately 50 clients with compression enabled! Compression is supported only by Atheros wireless interfaces like the ones used in AT-WR4500 series. If disable-running-check value is set to no, the router determines whether the network interface is up and running - in order to show flag R for AP, one or more clients have to be registered to it, for station, it should be connected to an AP. If the interface does not appear as running (R), its route in the routing table is shown as invalid! If set to yes, the interface will always be shown as running.

On Atheros-based interfaces, encryption (WEP, WPA, etc.) does not work when compression is enabled. The tx-power default setting is the maximum tx-power that the card can use. If you want to use larger tx-rates, you are able to set them, but do it at your own risk! Usually, you can use this parameter to reduce the tx-power.

In general tx-power controlling properties should be left at the default settings. Changing the default setting may help with some interfaces in some situations, but without testing, the most common result is degradation of range and throughput. Some of the problems that may occur are: (1) overheating of the power amplifier chip and the card which will cause lower efficiency and more data errors; (2) overdriving the amplifier which will cause more data errors; (3) excessive power usage for the card and this may overload the 3.3V power supply of the board that the card is located on resulting in voltage drop and reboot or excessive temperatures for the board.

If the wireless interfaces are put in nstreme-dual-slavemode, all configuration will take place in /interface wireless nstreme-dualsubmenu, described further on in this manual. In that case, configuration made in this submenu will be partially ignored. WDS cannot be used together with the Nstreme-dual.
