Well, when I attempt to connect to the 3G mobile network (Huawei EM770) after previously disconnecting, it gets to authentication then complains it can't connect to the remote computer. However, I know it's a problem with Windows 7 because it works only after I restart. But if it drops out, I have to restart again to get it to work again, even if I try several times over an hour.
Any suggestions on how to fix this issue?
