Wireless

You can Enable or Disable the wireless LAN in this field.

Channel 

Set the channel depending on your particular region.

Select a channel or use Auto to have the ZyXEL Device automatically determine a 
channel to use. If you are having problems with wireless interference, changing the 
channel may help. Try to use a channel that is as many channels away from any 
channels used by neighboring APs as possible. The channel number which the 
ZyXEL Device is currently using then displays next to this field.

Bandwidth

Select whether the ZyXEL Device uses a wireless channel width of 20MHz or 
20MHz/40MHz.

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 300 Mbps.

40MHz (channel bonding or dual channel) bonds two adjacent radio channels to 
increase throughput. The wireless clients must also support 40 MHz. It is often 
better to use the 20 MHz setting in a location where the environment hinders the 
wireless signal. 

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 20MHz/40MHz to allow the ZyXEL Device to adjust the channel bandwidth 
depending on network conditions.
