CrashOverride-
Thank you for the info.
I know from personal experience that microwaves can cause interference, but I was unaware they had a specific frequency. (I know they work by having a magnetron generate the microwaves that bounce off of spinning blades, which disperses the waves over the food.)
The routers I worked with have channels 1- 11.

A few more questions:
3) Is somebody (that you know of) using a cordless phone or microwave when your problem occurs?
