If you're using 802.11g or 802.11b, which run in the 2.4 ghz frequency
range, you can get interference from things like microwaves and cordless
phones. These also operate in that frequency range. The wireless adapter
will lower the linkspeed when it has such problems to allow transmission in
the presence of noise.
Not all wireless adapters will report this variation in linkspeed though.
Some will just always says 54 mbps, even when they are running at a lower
linkspeed. Switching to 802.11a should address the problem. Changing
channels may also help- for instance, my microwave affects channels 6
through 11 but does not affect channel 1.
