The problem usually comes from the wall wart with RF getting into the power supply lead. Most modems us an external PS such as the infamous wall wart. Try wrapping the PS lead around the ferrite core as close to the modem as possible, the same with the Telco wiring . The other alternative is to get a modem with a internal PS. De W8VVG
