http://forums.opensuse.org – Hi! I am having trouble with KNetworkManager establishing wireless connections. After DL 43xx firmware I get to see the available wireless networks, after clicking on my network KNetworkManager then asks about the password for my network, I enter it and then nothing happens for a while and then it asks me again for the password and then the whole process is repeated over and over again with no connection ever established. What is wrong? (Distributions)
