Appliance/Cordless phone interference with Router

Okay, so I went to Staples about 2 weeks ago to pick up a wireless router. I was going there expecting to get a Netgear router ( not sure which one, it was around $100)..the guy talked me into getting this dirt cheap Belkin router because he said it's only for 1 computer and it's such a small area..I bring it home and it works fine..UNTIL..I decide to make..popcorn in the microwave. My wireless connection slows down to an almost dead stop! It goes about 1/4 the speed of dial-up! Then, if someone calls the house phone and I'm on the comp, the minute I pick up, my wireless connection drops entirely! Why is this?

it is because they are both on the same channel, go into your routers chanel and change it from whatever it is, most likely 11, to something like 8 or 12. should do the trick...

OR, just dont use the microwave or talk on the phone
