Firstly, I would like to say that using a wireless network which is not yours, will probably land you in some trouble. But, hey, it’s not for me to judge, I’m just here to provide the information!

After very recently looking for some admin-like answers to some wireless network problems I was having, I found this article that details in a Make Magazine or Instructables style, how to create a “Predator” wireless access point sniffer.

The Predator is a hacked router and huge wireless receiver, plus a tripod. It will scan the surrounding area for the strongest unencrypted, or “open” wireless network and repeat it into your network. And because of the over-average size of the receiver, you should be able to get a good signal as long as you have a fairly good line-of-sight. So you will have free wireless internet, while still retaining control of your network security. Very cool, but remember it might be illegal depending on where you live and laws in that country etc. Also, I wouldn’t suggest sticking the thing right next to the window as in the pictures, unless you want the SAS zip-lining into your lounge after reports of a sniper in your building!
