I switched to ubuntu after the new LTS release and was having some problems with my MTS Mblaze connection. Sometime’s it’d work and sometimes it wouldn’t. There seems to be a bug in modem-manager which constantly keeps crashing so I decided to use wvdial instead. We need to install the wvdial package
sudo apt-get install wvdial
and then create the file /etc/wvdial.conf
[Dialer mts] Stupid Mode = 1 Inherits = Modem0 Password = mts Username = email@example.com Phone = #777 [Modem0] Init1 = ATZ SetVolume = 0 Modem = /dev/ttyUSB0 Baud = 115200 FlowControl = Hardware (CRTSCTS) Dial Command = ATDT
Then we can connect to the internet using
sudo wvdial mts
This is the output that I get when the dialer is run. Occasionally it will have some problems you can just disconnect and try again.
