Why Wireless and Powerline Networks Fail

Maybe experts are wrong about frequencies and interference.

Many of us have noticed that the microwave oven can interfere with our wireless home networks. It happens to me on the weekend, when I'm casually surfing the Web or uploading photos while sitting in the kitchen with a laptop. I'll stick in some microwave popcorn and—poof!—no Internet connection.

So now Donna, my sister-in-law, reports that she runs into interference with her powerline network that sends Internet data across her in-wall wiring. It happens when she uses a countertop popcorn popper.

Experts will say it has to do with radio frequencies—the appliances are sending signals into the air or across the wiring at wavelengths that interfere with the data.

I think it's the popcorn.
