Using Aluminum Oxide Paint To Secure Wi-Fi
eldavojohn writes "The BBC reports on people using aluminum oxide in their paint to block Wi-Fi signals from leaving their home or business. Aluminum oxide resonates at the same frequency as Wi-Fi signals and other radio waves, blocking data from going outside a building. It's not a flawless solution, as it may also block AM/FM signals. You or your neighbors may be unwittingly using this already, as most pre-finished wood flooring uses aluminum oxide as a protective coating."
I'm already using aluminum foil lining in many of my hats and clothes to protect me from the government transmissions. However, I hadn't heard that Al2O3 was any better than straight aluminum foil.
It seems suspicious that this story would be posted immediately after I began considering papering my walls with foil.
...a way to stop wearing this itchy tinfoil hat!
Then != than you morons.
Wouldn't you have to paint over the windows?
I dipped my head in this aluminum oxide paint, and it keeps all their signals out. Granted, I look somewhat like a cyborg now, but this stuff should work just fine for an office trying to keep their signals in.
Authority questions you. Return the favor.
Admit it. You're just bitter that your neighbor finally turned on WPA2, and now you have to go to the library to read Slashdot.
So you went inside a Faraday Cage with an unprotected ethernet cable and managed to get cell phone reception. I on the other hand, can't get cell phone reception if I stand too close to my filing cabinet. I either need to switch to your provider or you need to come do your WiFi experiments next to my filing cabinet.
Plug your filing cabinet in to your router?

I use encryption and MAC address lists together because it means that if somebody wants to get in they have to do two things instead of just one.
