A standard 20MHz channel offers transfer speeds of up to 150Mbps whereas a 40MHz

channel uses two standard channels and offers speeds of up to 300Mbps. However, not all

devices support 40MHz channels.

Select the channel bandwidth you want to use for your wireless network.

It is recommended that you select

20/40MHz

. This allows the NWA to adjust the channel

bandwidth depending on network conditions.

Select

20MHz

if you want to lessen radio interference with other wireless devices in your

neighborhood or the wireless clients do not support channel bonding.

Select SSID

Profile

The SSID (Service Set IDentifier) identifies the Service Set with which a wireless station is

associated. Wireless stations associating to the access point (AP) must have the same

SSID. You can have up to four SSIDs active at the same time.

Note: If you are configuring the NWA from a computer connected to the wireless LAN and

you change the NWA’s SSID or security settings, you will lose your wireless

connection when you press

Apply

to confirm. You must then change the wireless

settings of your computer to match the NWA’s new settings.

#

This is the index number of each SSID profile.
