What happens when you move the mouse receiver away from the WRT54G?

The MS Mouse run on about 27MHz. The WRT54GS runs at 2400MHz. In
theory, there should be no interference.
I have several customers with the new MS wireless mouse and keyboard
combination. The range sucks. I can get totally reliable performance
from the older units, or from Logitech systems, up to at least 6 ft.
The new MS devices will barely penetrate a 3/4" oak desk, barely work
to 3ft, and acts flakey. It also has a very fast "sleep" mode to save
power that causes erratic startup behavior. I found that I had to put
the receiver almost in front of the monitor for it to work. On other
wireless keyboards and mice, I could hide the receiver almost anywhere
on or under the desk. I was not impressed.
The lack for range and sensitivity may be intentional. It's always a
problem to have a mess of wireless keyboards and mice in one office.
Although one mouse will not take over a different machines system,
they do interfere with each other by creating erratic behavior. By
reducing the range and sensitivity, they probably throught they could
increase the number of systems allowed in one area. Same with the
aggressive sleep mode. It improves battery life, even if it drives
the user nuts.
The typical mouse receiver is a joke. The receiver is not very
sensitive, but almost any strong RF signal will cause it to go into
"blocking". Blocking is where the receiver input stage is saturated
with enough RF to cause rectification, effectively turning it off. My
guess is that the beacon transmissions from the access point are
trashing the mouse receiver in this manner.
The problem can also appear at the mouse transmitter end. Shove
enough RF into the transmitter, and it too can rectify the RF, causing
it to shut off. This is less common, but still possible.
Lastly, the wall wart power supply for the WRT54GS might be a
switching supply causing RFI and EMI that is being received by the
mouse receiver. If the wall wart is a small comparatively light
weight unit, it's a switcher. The WRT54G will run on any wall wart
from 5VDC to perhaps 15VDC (negative ground) so you might try a
different wall wart.
