Select the bandwidth for the network. In high wireless activity/interference
environment, reduce band to 20MHz for better stability.
If you select 20MHz in Both Bands you cannot select sideband does not
work as you are not utilizing side bands. When you select 40MHz in Both
Bands as the bandwidth and manual select channel, the following options
will appear. Then you can select Lower or Upper as the value of sideband. As
the control sideband, when you select Lower, the channel is 1~7. When you
select Upper, the channel is 5~11.
Select the transmission rate for the network. The rate of data transmission
should be set depending on the speed of your wireless network. You can
select from a range of transmission speeds, or you can select Auto to have
the Router automatically use the fastest possible data rate and enable the
Auto-Fallback feature. Auto-Fallback will negotiate the best possible
connection speed between the Router and a wireless client. The default
value is Auto.
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.
Only stations that are configured in 802.11n mode can associate.
Allows you to specify the maximum bandwidth of the 802.11g network.
Select the multicast transmission rate for the network. The rate of data
transmission should be set depending on the speed of your wireless
network. You can select from a range of transmission speeds, or you can
select Auto to have the Router automatically use the fastest possible data
rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the
best possible connection speed between the Router and a wireless client.
The default value is Auto.

packets. Try to 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.
This value should remain at its default setting of 2347.
Should you encounter inconsistent data flow, only minor reductions are
recommended. If a network packet is smaller than the preset RTS threshold
size, the RTS/CTS mechanism will not be enabled. The Router sends Request
to Send (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
