Also according to this lot, wireless thingy wotsits are crapola:
The WEP security protocol that encrypts data carried over WiFi networks, used widely by businesses and consumers, can be cracked in seconds with nothing more powerful than a standard laptop PC, according to security researchers from Darmstadt University of Technology in Germany. The researchers claim that they have discovered flaws in the WEP algorithm which would enable a hacker to identify the security key required to gain unhindered access to the wireless network in very little time, less than a minute to capture the required data and then just a few seconds to extract the key from that data.
The WEP protocol has never really been considered particularly robust, and this discovery renders it practically useless as a serious security tool. Organisations using wireless networks to carry any sort of sensitive information are advised to use the more advanced WPA protocol which is available on more modern wireless equipment, or to consider third party security products to strengthen their networks.
