System
It is case-sensitive and cannot exceed 32
characters.
Selects one IEEE 802.11G channel for
wireless LAN transmissions from the
drop-down list.
Specifies the bandwidth which the wireless
radio operates. AP and the client stations that
is associated work in one of channels from 1
to 14.
Description
Type the time interval in milliseconds
between beacons broadcast by AP
(Access Point) in the Beacon Interval box,
such as 100.
Type a number in the RTS Threshold box.
Also called Request-to-Send Threshold.
This field specifies the minimum size of
data frames above which RTS protocol
is used, ranging from 256 to 2432. RTS
helps prevent data collision from hidden
nodes.
Type a number in the Fragmentation
Threshold box.
For efficiency in high-traffic situations,
large files are split into fragments. This
field specifies the default packet size, an
even number ranging from 256 to 2346.
Type a number in the DTIM Interval box.
Also called Delivery Traffic Indication
Map. This field specifies the number of
beacon intervals between successive
DTIMs, ranging from 1 to 255.
Select either Short Preamble (72 bits) or
Long Preamble (144 bits).
If you want to use Wireless Distribution
System on your Router, click Enable
next to Distribution System, then type the
