Just a general question (not looking for a solution yet).
Dual booting the same laptop, a Verizon (Qualcom 3g CDMA) works very well on the Ubuntu side - no password or user ID required. I can disconnect and reconnect - and sometimes I have to unplug and plug the modem back in but, all in all, it plugs and plays.
Opensuse Gnome - It plugged and played the first time - no password or user ID required. Then I disconnected and was not able to reconnect. Every time I click on Broadband Wireless, I am told that the connection is disconnected. (Thanks, I knew that.)
Opensuse KDE - It plugs but it doesn’t play. I’ve really come to question the viability of KNetwork Manager. I had a heck of a time just getting wireless to work. Is KDE’s network manager a beta? I don’t get why Gnome works so much better? I’ve more or less given up on KDE… for now… Am I the only one?
When I tried to get my 3g wireless modem working, Knetwork manager gave me lots of grief and I abandoned it for Yast-ifup.
What I did discover with my mc950d wireless 3g modem was that YAST configured to use ifup instead of Knetwork_manager and shutting down the ipv6 made life real easy.
True I did have to check out the novatel mc950d on the web to get it working good but then that’s power for the course. There is a reference to what I did on this forum that might help, just search for mc950d.
Depends on versions; the version that came along with KDE 4.1.x/4.2 was pretty useless, but then it wasn’t really a KDE 4 version of Networkmanager, just a hack on a previous version that sort-of did something.
At some time (I’m guessing around 4.3.2, but I’m not that sure of the exact version) Network manager got the re-write it deserved and became a fully-fledged KDE 4 app. That works much, much, much better now for me, although I’m not testing it in your exact use case.
