Not quite found, because it doesn't mean that even if you downgrade nm- applet, you'd be able to use the modem. Could you try that? I haven't changed code paths that would have such an effect, unless the modem was already disabled with wifi enabled, but that would be in the state file.
Also, is there anything indicating an rfkill switch for the modem in "rfkill list" ? ** Changed in: network-manager (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/705196 Title: Network Manager no longer supports mobile broadband connections -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
