I installed a new 11.2 and now my huawei e1692 works (thanks to huawei e1692 don’t work - openSUSE Forums).
kde=Versione 4.3.4 (KDE 4.3.4) “release 2”
kernel=2.6.31.5-0.1-desktop
NetworkManager | Network Link Manager and User Applica… | 0.7.1_git20090811-4.2
NetworkManager-kde4 | NetworkManager client for KDE 4 | 0.9.svn1043876-4.7
huawei e1692 works, but if I manage connections with knetworkmanager the broadband tab is grey and not clikable, how can I connect by knetworkmanager?
