This austere website helps you to make a your very own 2,4 GHz spectrum analyzer.
What in the world is this electronic device for ? It finds the best channel for your Wi-Fi (802.11b) network of course !
Between the micro-wave ovens, video transmitters, DECT phones and other wireless gadgets all using the same frequencies as Wi-Fi, it is often useful to know which frequency is best to use. Our Wi-Fi software can only detect Wi-Fi signals, ignoring all the other noise.
With a spectrum analyzer, you can see which frequencies are available, and tell your Wi-Fi hardware to use the corresponding channel !
While waiting for more intelligent technologies capable of dynamically choosing a channel depending on the interferences, it is best to opt for the analyzer solution if your network encounters slow transfers or loss of data.

Caffe Latte is a new attack against WEP, the most reknown but less performant security for Wi-Fi networks.
Vivek Ramachandran and Md Sohail Ahmad from AirTight Networks can exploit a laptop when it’s user tries to connect to an access point protected by a WEP key.
This man-in-the-middle attack is transparent for the user as he gets Internet access from the hacker while the latter detects the security key. Even though the latest WEP hacking techniques enable to find the key in a couple of minutes, Ramachandran and Ahmad’s technique takes around 30 minutes, which is still quite fast !
The new hacking technique will be presented this week-end in San Diego during the ToorCon conference.
