Apply this paint to your walls to keep neighbors off your wireless network.

Wireless security and encryption systems are fraught with problems and insecurity, and other methods to restrict your signal to a small area are cumbersome at best.

Enter a new solution: Anti-Wi-Fi paint.
BBC NEWS | Technology | Anti-wi-fi paint offers security

The idea is simple: Use a special paint on walls where you don't want wireless to pass through (say the exterior of your house). The secret is mixing aluminum-iron oxide particles in with the paint. The metal particles resonate at the same frequency as Wi-Fi and other radio waves, so signals can't pass through the thin layer of pigment. Outsiders would simply be unable to access your wireless network, just as you, inside the house, won't be able to interlope on anything beamed on the outside.

Yeah, and block off your cordless phone signal outside the house as well. Very smart.

Its like that joke where a moulvi told this guy that keeping a dog at home keeps the "farishta's" out. So the guy replies: "malaikul maut bhi tho aik farishta hee hai na!!!!"

^ I know it's a joke but what that maulvi meant was that dog keeps "rehmat kay farishtay" away.

Anyhow, unless you work for ISI, you shouldn't be this paranoid.
