Version:            (using KDE 4.2.90)
Installed from:    Ubuntu Packages

I used to connect to my wifi network using the network manager widget, but sudently it stopped working. The network is listed in widget, but when I try to connect to it after couple of minutes I get "Enter network connection secrets" window (although the wpa key is stored in kwallet). When I put the passphrase it still cannot connect and after another couple of minutes the same password asking window is displayed. I've double checked the password, my other laptop connects to the network without any problems (knetworkmanager and kde3).
