Field Name Description
802.11ac Band The band you are configuring: 2.4 GHz or 5 GHz.
Channel Select the Wi-Fi channel you want to use. The current channel number displays to the right of the field. For
the 5GHz band, options are Auto and 36 through 157. For the 2.4GHz band, options are Auto and 1 - 7. The
default is Auto.
All devices in your wireless network must use the same channel in order to work correctly.
Auto Channel Enter the frequency (in minutes) at which the gateway scans channels for interference. If a threshold of
Timer (min) inference is detected, a new channel will be selected automatically. Options are 0 - 65535 minutes. The
default is 15 minutes.
MIMO-OFDM This option is set to On and cannot be changed.
Bandwidth Select the operating bandwidth. Options are 20 MHzand 40 MHz. The current bandwidth setting displays to
the right of the field.
Control Sideband This option is set to Lower and cannot be changed.
MIMO Data Rate The desired physical transmission rate. This option is set to Auto (the Auto-Fallback feature is enabled) and
cannot be changed. This allows the gateway to automatically use the fastest possible data rate. Auto-Fallback
will negotiate the best possible connection speed between the gateway and a wireless client.
RTS/CTS Protection Select whether to enable 802.11n and legacy clients to both work effectively on the network. Options are:
Support MIMO Select whether to restrict non-MIMO clients from accessing the gateway. Options are On and Off. The default
Clients Only is Off.
RIFS Advertisement RIFS (Reduced InterFrame Speed) is the time in micro seconds by which the multiple transmissions from a
single station is separated. This option Improves performance by reducing dead time required between OFDM
transmission. Options are Auto and Off. The default is Auto.
OBSS Co-Existence Coexistence of Overlapping Basic Service Sets (OBSS) prevents overlapping in the 20 MHz and 40 MHz
frequencies. Options are:
RX Chain Power Select whether power-save mode is enabled. Options are Disable and Enable. The default is Enable.
Save
Note: Before setting this parameter, make sure that
RX Chain Power Enter the number of minutes that will elapse before quiet time begins. The default is 10 minutes.
Save Quiet Time
RX Chain Power Enter the throughput threshold(in seconds) for when the router engages power save mode after the quiet
Save PPS time seconds have elapsed. The default is 10 seconds.
54g Rate This option is set to 6 Mbps for the 5 GHz band and to 1 Mbps for the 2.4 GHz band and cannot be changed.

Auto: Provides maximum security but produces a noticeable impact on throughput. With this
l
option, RTS/CTS behavior permits legacy clients to become aware of 802.11n transmit times,
but decreases overall throughput. This is the default.
Off: Provides better throughput.
l
Enable: The gateway automatically reverts to 20 MHz channel bandwidth when another WiFi
l
network within 2 channels of its own channel is detected or when a client device with its 40
MHz Intolerant bit set is detected.
Disable: The gateway advertises and operates in 40 MHz mode regardless of how other nearby
l
networks are configured. This is the default.
802.11n/EWC is set to Auto.
