I'm using Mobile Broadband with the modem HUAWEI K3765 . I have installed the driver from here : http://www.betavine.net/bvportal/resources/datacards/devices .
In the modem's official management application (supporting only Windows OS, not Linux) there is an option for using either an EDGE or 3G connection, depending on the signal strength.
Using this option, the modem defaults to 3G. Only when the signal is low, it automatically connects via EDGE. You can suppress this behavior by choosing the option "Connect via 3G only".
Now I'm using Ubuntu 11.04. As I said I couldn't install the official application, I just installed the mentioned driver. This modem automatically connects via EDGE when 3G signal is low. I want to connect via 3G always, also when the 3G Signal is low.
So what I should do?
