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
Timer (min)
Enter the frequency (in minutes) at which the gateway scans channels for interference. If a threshold of
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 MHz
and
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:
l
Auto:
Provides maximum security but produces a noticeable impact on throughput. With this
option, RTS/CTS behavior permits legacy clients to become aware of 802.11n transmit times,
but decreases overall throughput. This is the default.
l
Off:
Provides better throughput.
Support MIMO
Clients Only
Select whether to restrict non-MIMO clients from accessing the gateway. Options are
On
and
Off
. The default
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:
l
Enable
: The gateway automatically reverts to 20 MHz channel bandwidth when another WiFi
network within 2 channels of its own channel is detected or when a client device with its 40
MHz Intolerant bit set is detected.
l
Disable:
The gateway advertises and operates in 40 MHz mode regardless of how other nearby
networks are configured. This is the default.
RX Chain Power
Save
Select whether power-save mode is enabled. Options are
Disable
and
Enable
. The default is
Enable
.
Note:
Before setting this parameter, make sure that
802.11n/EWC
is set to
Auto
.
RX Chain Power
Save Quiet Time
Enter the number of minutes that will elapse before quiet time begins. The default is
10
minutes.
RX Chain Power
Save PPS
Enter the throughput threshold(in seconds) for when the router engages power save mode after the quiet
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.
