◗ 802.11a Channel Selector
These options extend the range of 802.11a wireless capability by allowing

enable an 802.11a channel of your choice.
◗ 802.11g Channel Selector
These options extend the range of 802.11g wireless capability by allowing
you to select 802.11g wireless channels. Check the corresponding box to
enable an 802.11g channel of your choice.
◗ 802.11g (only)
These options allow you to set up how your 802.11g wireless module
performs (not applicable to 802.11a radios). Options that are specific to
802.11g radios include:
• Protection Mode
This is a mechanism to let 802.11g devices know when they should use
modulation techniques to communicate with another 802.11b device,
especially in wireless networks where there is a mixed environment that
has 802.11g and 802.11b clients (and the clients are hidden from each
other. The protection mode options are:
– None
This assumes there are no wireless stations using 802.11b (11 Mbps)
technology. If operating in a mixed 802.11b/g network with minimal
802.11b traffic, choose this option to ensure the best performance for
your 802.11g stations.
– Always
Protects 802.11b traffic from colliding with 802.11g traffic. This
mode is not recommended, especially if only a few wireless stations
are operating with 802.11b. Only use this mode in environments
with heavy 802.11b traffic or where there is interference.
