USB Modem not working
I have ZTE USB modem. In older version of Ubuntu (11.04, 11.10) I had installed SAKIS3G tool. So my dongle appear in the Network Selection dropdown list. I just configure it and it's working.
But in Ubuntu 12.04, I cannot see it. After some googling, I find that it will be detected on boot. So I have inserted it and rebooted my system and it's detected. Than it's connected and working perfectly but after two-three minutes it's disconnected and removed from the network dropdown. So I cannot see or select it.
Can you help me so I can connect to my 2G internet connection via my ZTE dongle?
