Using Aluminum Oxide Paint To Secure Wi-Fi

Posted by Soulskill on from the prank-possibilities-abound dept.

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."

  1. Does not resonate with me by Ancient_Hacker · · Score: 5, Insightful

    Dunno where they got the crap about "resonates".

    The paint might act as an electrostatic shield, or as a lossy dielectric, both effects that will attenuate RF signals.

      But resonate, no.

    You select WPA2-PSK in your router's config, press "generate key", make a note of the generated key, connect your laptop to the encrypted WLAN, enter the key, done. No beacon disabling, radio frequency shielding, MAC filtering, DHCP disabling or other nonsense necessary. It's like people are trying to test every option but the right one.
