Mode
Specify the wireless mode in the 2.4-GHz band by making a selection from the 
drop-down list:
•  g and b. In addition to 802.11b- and 802.11g-compliant devices, 
802.11n-compliant devices can connect to the wireless access point because 
they are backward compatible.
• g only. 802.11g- and 802.11n-compliant devices can connect to the wireless 
access point, but 802.11n-compliant devices function below their capacity in 
802.11g mode. 802.11b-compliant devices cannot connect.
•  ng. This is the default setting for most countries. 802.11g- and 
802.11n-compliant devices can connect to the wireless access point. 
802.11b-compliant devices cannot connect.
•  n only. Only 802.11n-compliant devices can connect to the wireless access 
point.
Note: 
If your network uses 802.11n devices only, configure WPA2 to enable the 
802.11n devices to function at full speed.
Channel Spacing
For the ng and n only modes, specify the channel spacing by making a selection 
from the drop-down list:
•  20/40MHz. Select this option to improve the performance. Some legacy 
devices (that is, devices that function only in b or g mode) can operate only in 
20 MHz.
• 20MHz. Select this option if your network includes legacy devices. This is the 
default setting.
Note: 
The channel spacing is fixed at 20 MHz for the g and b and g only modes.
Current Channel
This is a nonconfigurable field that shows the current channel if you have 
selected Auto from the Channel drop-down list.
Channel
Specify the channel you wish to use on your wireless LAN by making a selection 
from the drop-down list. The wireless channels and frequencies depend on the 
country and wireless mode. The default setting is Auto.
Note: 
It should not be necessary to change the wireless channel unless you 
notice interference in the network (indicated by lost connections or slow data 
transfers). If this happens, you might want to experiment with different channels 
to see which is the best. For more information, se
following this table.
Note: 
For more information about available channels and frequencies, see
