Hi there,

I have recently upgraded my laptop to Ubuntu 11.04 from 10.10.
I am having a problem connecting to wireless networks using WPA security (in work). At home, I can connect without any problem to my own wireless connection which uses WEP security.

Has anyone got any ideas for what I could try so that I can connect to WPA wireless networks?

Below is some information that may be of help.
Also, the laptop can see the network in work, but it cannot connect. It continually asks for the key. I have entered the correct key on each occasion with no joy. Any help would be very much appreciated.

Update 03.08.2011: I noticed there was a build up of wireless connections of the same name in the list (might have been the failed attempts). I deleted all these connections of the same name and when I switched on the laptop in work this morning I was prompted with a message stating that there were wireless connections available. I selected the one I wanted and entered the key and success: I am connected.
