I am facing a peculiar problem with 12.04. I have a Huawei E173 3G USB modem.
It is working fine, connects to Internet correctly, showing data traffic on display, but the only problem is that, Network (Internet) is not available to 'Administrator' user other than 'root' user.
This is why those application have root access like Software Center and Synaptic can connect but normal browser wouldn't connect. I have only one user account on this system.
Please help me, I am getting frustrated. What is the problem?
