Can it be some kind of « power pollution » ? Some devices eat current in a 
quite nonsmooth way, and this disturbs the current that other devices can 
get from the same set of power outlets.

For example, 20 years ago, I plugged the CCR-81 cassette recorder into the 
same power bar as a PC running a BBS with a 2400 or 14400 bps modem. The 
modem stopped recognising any incoming call. I unplugged the CCR-81 and 
voilà, it worked again.

And much more recently, I was getting a huge noise in the speakers and/or 
microphone in somebody's basement, but only sometimes. It took a while to 
find out that it happened only while someone else used the microwave oven 
on a different floor...

(All of those outlets had working ground pins, all affected equipment had 
ground pins, and the microwave also had a ground pin. The only thing that 
didn't was the CCR-81.)
