Has happened here too, to my wife's Mac. The Airport Extreme is in my office, and there's a number of walls between me and her office. If the microwave runs, we'll lose some (or all) of the signal. The Airport Express in the kitchen (attached to the radio) will also completely cut out if it's streaming iTunes. The kids' Mac (on the floor almost right above me) will not lose any signal at all that we've noticed.
