Re: [Nolug] Unsecured wireless networks with everybody's favorite OS

Here's a crazy idea. Go ask the neighbor to secure his access point.
Tell him it's a hazard to your business as well as his own. If he
refuses, setup a sniffer and send disassociation packets everytime you see
a new MAC on the network.

Unless he's a coffee shop? Then offer to turn off your sniffer in
exchange for free coffee :)
