Hello Alexander, I have upgraded the system with the new packages of Network Manager as you told me, and so far all the connections are working correctly. I am going to test it more times (connecting and disconnecting the modem and rebooting the system) and I will inform you if something fails.
Thank you very much. -- NetworkManager HUAWEI E220 +COPS Invalid Byte Sequence https://bugs.launchpad.net/bugs/311508 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
