Table 10. Access point channels and associated center frequencies
Note that only channels 1, 6, and 11 are non-overlapping.
It is not possible to configure access points to use different channels. If the channel
for wlan2 is changed, the channel will be changed for wlan1, wlan3, and wlan4.
However, different nodes in a mesh cluster can be set to use different access point
channels in order to reduce co-channel interference.
CLI
The AP channel is set with the „channel‟ parameter in the „wlanN‟ interfaces. The example
below shows how to set the AP channel to 6.
> use wlan1
wlan1> set channel=6
Web GUI
The access point channel can be set via the web interface using the appropriate “wlanN” tab
on the “Wireless Interfaces” page (see Figure 32).
9.5 ESSID
The ESSID, or Extended Service Set Identifier, is used in 802.11 infrastructure networks to
identify a particular network. It is used to differentiate logical networks that operate on the
same channel.
