Field Name Description

Band Pre-set at 2.4 GHz for compatibility with IEEE 802.11x standards.

Channel [Auto, 1-11] Select the Wi-Fi channel you wish to use.

Auto Channel Timer(min) [0-65535 minutes] Set the frequency with which the gateway scans channels for in-

terference. If a threshold of inference is detected, a new channel will be auto selected.

802.11n/EWC [Auto, Disabled]

Reference, IEEE 802.11n Draft 2.0 for details on this standard.

Bandwidth [20MHz, 40MHz] Select the Bandwidth. 40MHz bandwidth provides better through-

put by taking advantage of two, adjacent 20MHz bands.

Control Sideband [Upper, Lower] Select the appropriate sideband to minimize RF interference from

adjacent channels and maximize the throughput. Sideband controls only available

in 40MHz mode.

802.11n rate Select the desired physical transmission rate.

802.11n protection [Off, Auto] Select Auto for maximum security but there is a noticeable impact on

throughput. Select Off for best throughput.

Support 802.11n client only [On, Off] Select On to restrict 802.11b/g clients from accessing the gateway.

RIFS Advertisement [Off, Auto] Reduced Inter-Frame Space RIFS. Improves performance by reducing

dead time required between OFDM transmissions. Recommended primarily for

greeneld deployments only.

OBSS Coexistence [Enable, Disable] Coexistence of Overlapping Basic Service Sets that prevents over-

lapping in the 20MHz and 40MHz frequencies.

If set to Enable, the gateway will automatically revert to 20MHz channel bandwidth

when another WiFi network within 2 channels of its own channel is detected or when
