View Full Version : [ubuntu] Problem using mobile broadband and wire network at the same time

July 11th, 2011, 03:19 AM
Dear all,

maybe someone can assist a beginner to solve a problem. I have set up mobile broadband and wired network in the network manager in Ubuntu 11.04. Yet, they won't work at the same time. Wired network seems to have priority and is connected at start up. To get the mobile broadband connection running I have to manually delete the wired network from nm every time. The other way around I can get the wired network running by disabling mobile broadband. I tried to fix things by manually configuring the wired network, but it didn't help.

NM in Ubuntu seems to see these two connections as two different networks and doesn't accept them running at the same time. In Windows 7 as well as in XP the same combination works without any problems.

Any idea how to fix this problem? Maybe by handling mobile broadband through wvdial and wired network through NM? This may be a workaround, but I'd prefer to handle both connections through NM.

Any help is very appreciated.
