Yes, it is very possible that the microwave oven is interfering with your 
wireless internet.  Microwave ovens use microwaves or radio waves with 
frequencies around 2.5 GigaHertz (GHz); this corresponds to the ISM band (for 
Industrial, Scientific, and Medical applications)that the Federal 
Communications Commission (FCC) has made available for wireless networking.

Moreover, the wireless networking uses very low level signals - so they could 
be prone to interference from the 2.5 GHz signals coming from the microwave
