Hi David, The internet connections in his house are very likely not as well grounded/connected with quality cat5 or better wire, and the entry point of stray rf, could be any one of the runs of internet wiring that he may have strung around. A clue may be, how much power does it take to "mess up" his connections. During the initial conversation it would be good to establish if it is any connection or just one that is a problem... any website... any location in the house... or every location... what does he have for a router?? Wireless or wired?and when did it start? Relative to when he added or changed something? That would a clue to locate the offending connection. Good luck, this is a tuff one... lots of pitfalls... to watch out for... you don't want to suggest a complete wire change... you'll be wiring his house for network.... although... it sounds like that could likely fix it.
