Select the appropriate channel to correspond with your network settings.
All devices in your wireless network must use the same channel in order to
work correctly.
This gateway supports Auto channelling functionality (default setting).
The Current: channel number, together with the current level of detected
interference, will be displayed on the right.
Select 802.11n functionality to be either: Auto or Off
Select the bandwidth for the network: 20MHz, 40MHz or 80MHz (available for
5G)
In high wireless activity/interference environment, reduce the bandwidth to
20MHz for greater stability.
The Current: bandwidth will be displayed on the right.
For 54g mode, you can select 54g Auto, 54g Performance, 54g LRS or
802.11b Only.
This option is only visible when 802.11n mode is set as Disabled.
The 802.11n standards provide a protection method so 802.11b/g and
802.11n devices can co-exist in the same network without "speaking" at the
same time.
Select the basic transmission rate ability for the AP.
Select the multicast transmission rate in Mbps for the network. The rate of
data transmission should be set depending on the speed of your wireless
network. Available settings are: Auto, 6, 9, 12, 18, 24, 36, 48, 54
Select Auto to have the Gateway automatically use the fastest possible data
rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the
best possible connection speed between the Gateway and a wireless client.
The default value is Auto.
With OBSS (Overlapping BSS) set to On the Gateway automatically changes
the channel width from 40MHz to 20MHz to avoid interference with other
APs and then back to 40MHz, if possible.
Packets that are larger than this threshold are fragmented into multiple
packets.
Increase the fragmentation threshold if you encounter high packet error
rates.
Do not set the threshold too low, since this can result in reduced networking
performance.
The default setting is: 2346
The RTS Threshold is the minimum size in bytes for which the Request to
Send/Clear to Send (RTS/CTS) channel contention mechanism is used. The
Gateway sends RTS frames to a particular receiving station and negotiates
the sending of a data frame.
After receiving an RTS, the wireless station responds with a Clear to Send
(CTS) frame to acknowledge the right to begin transmission.
