Subject: Re: [FD] Jamming WiFi tracking beacons

I thought the B+ model was four ports, two controllers. I'm not interested
in modifying (or even providing) a connection so much as looking for
unrecognised devices. I had the idea of using them in a mesh, with only one
actually connected to a live network. I thought it might be a way of
listening to what other devices are already broadcasting when they search
for a Wi-Fi connection
