    That was going to happen. How long before WPA truly can't be used for the same reason and we're on WPA2+.

    Wireless had to start somewhere. Can't believe the equipment eircom send out to new broadband customers is wifi-enabled by default, using WEP.

    somebody ran it on an N800, got the key 19 seconds..

    supports 256bit WPA though

    it is possible to recover a 104 bit WEP key with probability 50% using just 40,000 captured packets. For 60,000 available data packets, the success probability is about 80% and for 85,000 data packets about 95%. Using active techniques like deauth and ARP re-injection, 40,000 packets can be captured in less than one minute under good condition. The actual computation takes about 3 seconds and 3 MB main memory on a Pentium-M 1.7 GHz and can additionally be optimized for devices with slower CPUs.

    It's great it does. If only even more wireless adapters on the market supported it as well.

    Considering the stats provided by Capt'n Midnight, even after capturing only a few thousand packets, the percentage accuracy of the generated key is quite frightening.

    Get an atheros card its worth the 30euro.

    I got an orinoco b/g with an exteranl connector to replace a RT2500 card which was deaf in comparison(just on the internal antenna) and works with open source madwifi drivers.

    Cm9s are dirt cheap two
