Use this field to configure IEEE 802.11b/g protection.
Both 802.11b and 802.11g wireless communications
occur at the same radio frequencies. When the CGN is
wirelessly connected to 802.11b clients and 802.11g
clients simultaneously, the performance of the link to
802.11g clients can deteriorate due to the presence of
the 802.11b clients. Because 802.11b and 802.11g use
different modulation techniques, 802.11b clients do not
understand 802.11g’s Request To Send (RTS) and
Clear To Send (CTS) messages, which ensure that each
wireless device transmits only when other devices are
not transmitting.
When B/G protection is active, the CGN prevents
802.11b clients transmitting over 802.11g transmissions
by first transmitting an announcement (known as a CTS-
to-Self) to 802.11b clients, stating that it intends to
transmit to 802.11g clients.
Select
Auto
to have the CGN control whether B/G
protection is active or not.
Select
Always-on
to use B/G protection at all times.
Select
Always-off
to never use B/G protection.
