I’m sitting in Chania airport (Crete) and waiting to go home after a wonderful week with my family. Chania is a very small airport, but they offer free WiFi. Unfortunately the wifi is really unstable and slow. So what do a wifi geek do? Start WiFi explorer.

Here is a great list of how not to build WiFi:

1. Use only 2.4 Ghz
2. Use whatever channel you may like
3. Use different Data Rates on your access-points
4. Let others use 40 Mhz on 2.4 Ghz
