Channel Bandwidth — The AP options for channel bandwidth include 5, 10,
20, 40 and 80 MHz. Using 20 MHz gives an 802.11g connection a speed of
54 Mbps and an 802.11n connection a speed of up to 108 Mbps, and ensures
backward compliance for slower 802.11b devices. Setting the channel
bandwidth to 40 MHz provides a connection speed for 802.11n of up to 300
Mbps. Using a channel bandwidth of 80MHz provides a connection speed up to
866.7 Mbps. (Default: 20 MHz; Range: 5 MHz, 10 MHz, 20 MHz, 40 MHz, 80MHz)
◆
Channel — The radio channel that the access point uses to communicate with
wireless clients. When multiple access points are deployed in the same area, set
the channel on neighboring access points at least five channels apart to avoid
interference with each other. For example, for 11g/n 20 MHz mode you can
deploy up to three access points in the same area using channels 1, 6, 11. Note
that wireless clients automatically set the channel to the same as that used by
the access point to which it is linked. (The available channels are dependent on
the 802.11 Mode, Channel Bandwidth, and Country Code settings.)
Selecting Auto enables the access point to automatically select an unoccupied
radio channel. (Default: Auto)
