Signal Strength: Shows the wireless signal strength of the connection between
the 108Mbps Wireless Network USB Dongle with the Access Point.
Data Rate: Shows the statistics of data transfer, and the calculation is based on
the number of packets transmitted and received.
The range of radio frequencies used by IEEE 802.11g wireless devices is
called a “channel”. Channels available depend on your geographical
area. You may have a choice of channels (for your region) so you should
use a different channel than an adjacent AP (access point) to reduce
interference. Interference occurs when radio signals from different access
points overlap causing interference and degrading performance.
Adjacent channels partially overlap however. To avoid interference due to
overlap, your AP should be on a channel at least five channels away from
a channel that an adjacent AP is using. For example, if your region has
11 channels and an adjacent AP is using channel 1, then you need to
select a channel between 6 or 11.
