. ARM can be enabled per AP or under the global setting. Navigate to
the
WLAN > Radio >802.11b/g
page to enable ARM on the b/g radio.
2 Set ARM Assignment to
Enable
from the pull down menu to enable ARM.
3 Set ARM Scanning to
Enable
to enable scanning on the AP.
4 The ARM Scan Interval and ARM Scan Time can be set on a per AP basis. These
values can be left to the default setting unless they need to be modified for spe-
cific environment.
5 The AP will scan the network and hop to the best available channel based on the
algorithm. Sometimes the clients may not be able to adapt to this kind of
dynamic AP channel change. To disable an AP from changing channel when a
client is connected to it, check
ARM Client Aware
.
