USB Modem not working

Last Modified: 2013-12-27
Hello experts,

I have recently received a Huawei - EC1260 modem which is used to connect to internet in my uncle's office, but it doesn't seem to work in the home pc. The home pc is Windows Vista Home Basic SP2 with the latest Windows updates installed, Intel CPU 1.73 Hz, 1.5 GB RAM, and its a 32-bit OS.

As soon as I connect this USB modem, Windows does the driver installations that are successful. There is an application called Reliance NetConnect (Reliance is the ISP that supplied this USB Modem), and this application gives an error 691: Debugger Terminated Thread.

I have tried looking within the help docs, but there is no explanation of this error in there. On doing some preliminary investigation, I've found that its an error from Windows directly. I have ensured that debugger is not switched on from within IE Advanced Options.

Any other things that I can try (also tried switching off firewall, didn't help)? Thanks in advance for any replies.
