Note that wireless clients automatically set the channel to the same as that
used by the access point to which it is linked. The available channels are
dependent on the 802.11 Mode and channel bandwidth settings. A setting of
Auto” lets the access point set an available channel with the least interference.
(Default: Radio 0 - Auto, Radio 1 - Auto)
Tx Power — Adjusts the power of the radio signals transmitted from the access
point. The higher the transmission power, the farther the transmission range.
Power selection is not just about coverage area, you also have to ensure that
high-power signals do not interfere with the operation of other radio devices in
the service area. (The range of power settings and defaults are dependent on
regulatory limitations for the radio band.)
ACK Timeout — Sets the acknowledgement timeout, which is used primarily
for long-distance connections. This timeout is used to make an adjustment for
link distance. It is based on the amount of time, in microseconds, that it should
take to transmit a frame to the other end of the link, be processed by the
receiving device, and have the ACK frame created and returned to the sending
device. (Range: 0-255 microseconds; Default: 32 microseconds)
Fragmentation Threshold (802.11b/g modes only) — Sets the maximum
frame size above which packets are fragmented. Using a lower threshold
reduces the time required to transmit the frame, and therefore reduces the
probability that it will be corrupted (at the cost of more data overhead).
(Range: 256-2346 bytes; Default: 2346 bytes)
