oh and that's not even considering the inverse square law. a typical home wifi antenna is omnidirectional, so the power drops off in all directions very quickly the further from the antenna you are. in a microwave oven, you're very close to the 'antenna', with a wifi router, you're usually many metres away, this has a significant effect on the amount of microwave energy your body is subjected to.
wifi is a data transmission system, not a power transmission system. it is designed to operate with extremely little power, not enough to even warm you up. and it's too low in frequency to penetrate your skin. just having your curtains drawn will let in far more powerful and dangerous radiation than having a wifi router in your house
