I've seen other topics regarding this but none of them seem to offer a solution.

I've install BT5 (Gnome 32) onto my Dell Inspiron Mini 1012 and it give me "Bad password" error when I try to connect to my wifi which use WPA2 with a PSK.

It has connected successfully a couple of time, but the majority of the time it give me an error.

There aren't any problems with the wireless network; I have several devices attached to it and working fine. I have restarted my router just to be sure and the problem persists.

I don't have network-manager installed.

Can anyone offer any ideas?

Many Thanks.
