Networkmanager-kde vs. Networkmanager-kde4

Hi all,
I am not sure if I am the only one having problems connecting to my WLAN with Networkmanager-kde4.
If I am using Networkmanager-kde everything is fine but I can’t get a connection with Networkmanager-kde4.
The WLAN is encrypted with WPA2-PSK and I am using OS 11.1 KDE4.2.4 64bit.
Does Networkmanager-kde4 not support WPA2?

Networkmanager is buggy. Try installing wicd through one-click install. Since Networkmanager worked on and off, i tried wicd and am still using it. No connection problems where ever I go

thanks a lot - I’ll give it a try…
Cheers, Markus
