Thanks. The tech said they looked at signal levels when I called and didn't
see anything. I didn't have a baseline at the time (I do now) and assumed
they'd see something there if there was something.

I do have the Netgear. So I'll keep this in mind when I call them again
(assuming it's really not a noise issue) though I'm not sure exactly what
happened here or how I can get them to try the same thing?
