Note:

(1). When bandwidth is set to 20 MHz, there would be no

extension channel that can be selected. The extension channel is

based on the main or primary channel. When the main channel is

set to channel 1, channel 5 will be used as the extension channel.

When the main channel is set to 9, the extension channel can be

channel 5 or 13.

(2). The availability of some specific channels and/or operational

frequency bands are country dependent and are firmware

programmed at the factory to match the intended destination. The

firmware setting is not accessible by the end user.

Bandwidth

Select the bandwidth:

•20 MHz: Sets the operation bandwidth as 20

MHz. when 20 MHz is selected, there would be

no extension channel available.

•20/40 MHz: Allows automatic detection of the

operation bandwidth between 20 and 40 MHz.

Choosing this mode allows you to use the

extension channel.

Extension Channel

This is the optional channel for use. Setting the

Bandwith to 20/40 MHz allows you to use this

extension channel as the secondary channel for

doubling the bandwith of your wireless network.

Protected Mode

In most situations, best performance is achieved

operating in an environment with heavy 802.11b

traffic or interference, best performance may be

achieved with Protected Mode turning On.
