In Ubuntu 12.10 USB-modem Huawei 171 from MTS is not connected to the network. First on the message
Are you registered on the network, immediately after that,
You are disconnected from the network.
This happened after there was an internal error notification Ubuntu. I did not pay attention, and closed by sending the report. After the reboot does not work. Settings are not changed. I am online with this modem in Windows 8. Could you tell me why it is not working, please.
