As for wifi, if they've added any microwave emitters in your area or you're using a microwave too closely to the wifi device, it could interfere. A safe bet is just to keep the router one room away from the kitchen.
Our microwave is in between my roommate's room and the router. Any time I go to nuke something he gets booted from his game. Made him lose an all time best score one night and he nearly killed me.
