I'm trying to figure out a way to detect a Wi-Fi 2.4 GHz signal Jammer. I am not looking into locating the location of the jammer but rather detect the jamming signal. How do i do so using only wireless adapters? How can i measure SNR, wouldn't that help?

If you just like to detect those jammers - SNR can be measured with tools like kismet, netstumbler, vistumbler.

But keep in mind:

  • Other WiFi channels will be in your SNR analysis.
  • A jammer is not the only way to take down a wifi network ;-)

Your are correct, however i was able to distinctively find the Jamming signal. I also just got a spectrum analyzer. I am studying attacks on all stack levels as well ;) – Security Apr 22 '13 at 2:43
