Something certainly to consider, they do have a number of laser printers in
the office and two huge Xerox scanner/copier/printer/fax machines that DID
come over from the old office to the new office.
I'll see if I can slip into the office this weekend and shut it all down to
see if it still drops after 10 minutes.

I thought about the laser printer possibility but I couldn't imagine how
it'd put out enough RF to nuke the Wi-Fi signal. But I do know from
tormenting the guy in the next office that when the heating element on my
laser printer goes off, it causes his flourescent lights to flicker. We put
a meter on it and saw a tremendous spike when it does the re-heat. Maybe if
a laser printer is on the same circuit as the access point the power draw is
causing the problem?
The energy conservation folks on campus say that older laser printers left
on 24/7 are a huge component of MSU's electric bill.
