Found the article: <http://www.heise-security.co.uk/news/87889>

Hmm, I think, WPA support in Ubuntu is not that bright yet. I tried to 
make WPA work on my laptop which was running Kubuntu 6.06 LTS (which IS 
the current LTS version). Knetworkmanager of that version knows nothing 
about WPA. Sad thing: I had to install Kubuntu 7.04, although in the 
beginning I switched to Kubuntu because of the time frame of support for 
the LTS version.

If you have an old laptop without hardware support for WPA, then WEP is 
the only encryption available. Therefore, WEP will probably be available 
in new equipment for a long time. If you only have WEP available, you 
might as well switch off encryption, because it is no real security. 
However, for legal reasons it may be an advantage to keep even WEP 
switched on. Then an intruder has to crack the encryption, which is 
illegal (at least in some jurisdictions).
