Windows 7: 3g USB modem, disconnect/reconnect problem

3g USB modem, disconnect/reconnect problem

I am having a problem with a 3g USB modem. I'm using it overseas through the local provider, and since I have been having trouble getting help from their customer service, I'm hoping someone here might have some ideas.

This is a ZTE modem which connects using software provided by the local service.

The problem started after a system restore. I don't know if the system restore caused it or this was just a coincidence but that is the only change I can remember happening before the problem began.

Now whenever I lose the connection or go offline, I cannot reconnect unless I restart my computer. Any attempt to reconnect before restarting results in a "Connection failure" message.

I have tried uninstalling and re-installing the modem software several times, quitting the restarting the software, taking the modem out and plugging it back in. Nothing has had any effect.

Since I can connect as usual after a system restart, I'm guessing the source of the problem is something in Windows 7 Networking settings.

I tried to undo the restore to see if that would solve the problem but no luck: restore not successful. I got the same message when I tried to restore to different points.

I'm guessing that there is something in my network settings that needs to be "reset" to get the modem working again. A restart is obviously resetting whatever needs to be reset. Does anybody have any ideas about what might be causing the problem and how I can fix it without restarting every time?

Thanks for your help.
