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-throughput
value 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-throughput
would correspond to numerically lower port cost. The cost is
recalculated every 20 seconds or when the
p-throughput
changes 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-slave
mode, all configuration will take place in
/interface wireless nstreme-dual
submenu, 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.
Example
This example shows how configure a wireless client.
