DESCRIPTION
You can Enable or Disable the wireless LAN in this field.
This shows the wireless band which this radio profile is using. 2.4GHz is the frequency used
by IEEE 802.11b/g/n wireless clients.
Set the channel depending on your particular region.
Select a channel or use Auto to have the 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 Device is currently using then displays next to
this field.
Click more... to show more information. Click less to hide them.
Select whether the Device uses a wireless channel width of 20MHz or 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.
