Paint your house to shield your WiFi
As wireless networks have proliferated, computer security companies have come up with increasingly complex defenses against hackers: password protection, encryption, biometrics. Insulating the interior of a house, apartment or office from radio-wave interference is a simpler concept that has yet to become a popular consumer strategy, but a new product called DefendAir from Force Field Wireless could change that.
Available online at forcefieldwireless.com, the product is a latex house paint that has been laced with copper and aluminum fibers that form an electromagnetic shield, blocking most radio waves and protecting wireless networks. Priced at $69 a gallon and available only in flat gray (it can be used as a primer), one coat shields Wi-Fi, WiMax and Bluetooth networks operating at frequencies from 100 megahertz to 2.4 gigahertz.
Two or three coats will achieve the paint's maximum level of protection, good for networks operating at up to five gigahertz. Force Field Wireless also sells a paint additive ($34 for a 32-ounce container, enough to treat a gallon of paint) and $39 window-shield films.
Harold Wray, a Force Field Wireless spokesman, said the paint must be carefully applied. "Radio waves find leaks," he said.
It should be applied selectively, he said, because it might hinder the performance of radios, televisions and cell phones.

The only problem is that your cell-phone won't work in the house.
I don't think you can tune a Faraday Cage for frequency.

Why not just tin foil the hole room your computer is in. total cost maybe 10 bucks worth of reynolds wrap.
Oh, swell idea. Let's repaint the entire house with a new kind of "conductive" paint, how long it lasts compared to regular paint, no one knows. Who cares if we have to pay a little more for it? If the house is on high ground, thunderstorms might be much more fun. That the cell phone won't work inside the house also does not matter. We're doing all this so we can avoid running a few cables for wireline ethernet. Brilliant, brilliant!
Unfortunately, it sank.

Wouldn't you just love living in a house that was painted battleship gray all over? And let's not forget the floors and ceilings while we're at it.
This stuff isn't new, ithas been around for years at around the same price even. It's called boat anti-fouling bottom paint. So not only will this paint keep your radiowaves safe, it'll keep barnacles from growing on your house. LOL
