I have openSUSE 13.2 x64 installed on laptop and desktop. On the second one it's impossible to connect to network, while on the first one it works ok. Network settings on both computers are 100% identical, network is controled by KDE NetworkManager (that shows "Connected" with zero in-\outcoming speeds), using of cloned MAC-address doesn't help: desktop cannot ping even gateway. Before openSUSE there was Linux Mint 14 x32, and everything worked. What should I do to fix that?
