I can see my network but when trying to connect after a while I get a pop-up asking "authentication required...". If I re-enter the password the same thing happens again. The network worked fine before upgrading to 11.04 and still works on other equipment.
The network LED can be switched on/off by pressing Fn-F11, but this does not help. Disabling and re-enabling the wireless does not help.
The network card is a Ralink RT3090, the PC a MSI U135
wlan0 Link encap:Ethernet HWaddr 40:61:86:42:f5:84

And iwconfig shows:

any help would be appreciated, I'd like not to have to re-install 10.10.
