Wireless connections are detected but connection fails!

Can someone help me? I've read through a few threads but it truly gives me a headache. I'm using Mageia 3 KDE version. It sees all my networks but connection keeps failing.
I've tried following the instructions in one thread--run 'drakconnect' in root and make it so that the network is controlled by network management and by the user but nothing has changed
