Hi Aleksander. I've had the same problem since I updated my Huawei E220 to firmware revision 11.117.10.02.00 and 11.313.02.00.01 as detailed in duplicate bug #932824 <https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/932824/>. Before firmware update (possibly with firmware 11.110.xx?) everything was working fine.
I can confirm that the "ports" branch works for me. Debug log of successful connection is attached. ** Attachment added: "Debug log of successful connection with ModemManager "ports" branch" https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/868034/+attachment/2745222/+files/ModemManager%20Ports%20branch%20Success%202.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/868034 Title: Huawei E220 and E1550 can't connect on Ubuntu 11.10 To manage notifications about this bug go to: https://bugs.launchpad.net/modemmanager/+bug/868034/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
