The IEEE 802.11g standard operates within the 2.4 GHz band at
up to 54 Mbps. Also note that because the IEEE 802.11g
standard is an extension of the IEEE 802.11b standard, it allows
clients with 802.11b wireless network cards to associate to an
802.11g access point.
Enable – Enables radio communications on the access point.
(Default: Enabled)
Radio Channel – The radio channel that the access point uses to
communicate with wireless clients. When multiple access points
are deployed in the same area, set the channel on neighboring
access points at least five channels apart to avoid interference
