Problem:  I'd like to extend the range at which I can use my wireless router

Solution Difficulty:  Moderate

  If your not the type to play around with computer with computer hardware you may be wondering what a cantenna is. Simply put it's a form of wave-guide antenna that focuses a radio signal and extends the range at which you can receive it. The science behind it is fairly simple but I will spare you the lecture and will proceed to the project.

  So why do you build a cantenna? For starters it's a great way to track down rogue wireless access points within a building. Because of the direction nature of the cantenna, you can easily figure out which way the signal is coming from and by using the overall signal strength, track it down. Another nifty advantage is that you can set up a peer-to-peer connection between two wireless computers over a much further distance. And last of course, is that you can easily poach wireless connectivity off anyone in the vicinity.
