Would it be possible to use a router with some kind of linux firmware and a laptop in a car as a radar detector?

    Yes, with the right hardware. We can't help you find the right hardware here. We could help you make it work if you had driver troubles. – Gilles 'SO- stop being evil' Jan 29 '12 at 23:30
  • For that day when every car has a wifi connection. – TGP1994 Jan 2 '13 at 23:33

No. For so many reasons. One obvious one:


Layman's explanation of the above: The router cannot “tune” to the needed frequencies.

(Then there's the DSSS vs burst detection, etc, etc, etc...)

  • yeah i figured it wouldn't be able to pick up the frequency, i just noticed somewhere that people talked about "radar detection" when discussing openwrt, it got my hopes up. you know that'd be cool though! – Marty Jan 30 '12 at 21:27
  • Just to make it clear: those radars interfering with Wi-Fi are the weather and military ones. – kirelagin Jan 7 '17 at 16:02
