WLAN problems on Thinkpad X121e (RTL8188CE) (BT5R3)
I have a problem with my Lenovo Thinkpad X121e (Realtek RTL8188CE) (Backtrack 5 R3). If I opened Wicd the first time (!) I got an error message like "Could not connect dbus". Now I want to connect to a WPA2-encrypted network with hidden ESSID. So I type in the ESSID and then the WPA-key and click on connect...but in 30% of all cases I get the error "Bad password". In 50% of all cases I get the error "Unable to get IP adress" and in 20% he says I'm connected. But the connection stucks after ~1 minute. Wicd says I'm still connected but I can't do anything. This problem(s) only happen at this computer, so it can't be a problem with the router.
If I try to connect to our university-network Wicd shows me the same network on two different channels (1 and 6). Channel 6 works fine. Same problem like home at the other channel.
Well, I don't know what to do. Maybe someone have an idea?
