Well, my interference in strange because it only happens every once in a while, but when it happens it directly coresponds to talking on the phone or even scrolling through caller ID. Pattern wise, once it starts interfereing, it's going to interfere for the next few phone calls, so perhaps he could look for that in his logs. Otherwise, perhaps he could call you when the link goes down to see if you were on the phone?

I've had remarkable good luck with my AP considering that I live in a college appartment building with plenty of microwaves and cordless phones... The only time I get a drop out is with my cordless phone, otherwise it's rock solid.
