USB Modem not working

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.

Use System Restore to go back to a restore point before installing your Huawei - EC1260 modem and try to install the driver in the link below in your Windows Vista Home Basic SP2.

Thanks for replying, I am not sure about the OS in his office. I will find that out. I might have to do some research about upgrading the firmware because this modem is locked to an ISP and not sure how much it can be changed or upgraded.
No problem, i have lots of this Huawei modems, various models, best for now is K3520, no problem w Vista, 7, MacOSX

There is an interesting twist, I also get 'Error 678: Remote Computer did not respond' sometimes. I have tried downloading the driver from the link you've supplied and tried to run uninstall to remove everything that is already installed. And then ran the installer to put in the driver again. Still get error 691 and error 678 occassionally.

My uncle doesn't know about system restore, so he is hesistant to let me do it lol.

How to upgrade firmware? And any other ideas?

Hahaha, cannot believe it... sometimes things can be so silly.. lol..

I had tried it earlier as well, but it worked only after I updated the driver. The username and password were not correct, and my uncle had told me that same settings worked in his office, so I didn't bother looking at the username/password and concentrated on the PC itself.

It turned out that the username/password had an extra zero in the beginning, which had to be removed to make it work. I had tried it earlier with the old driver, but it didn't work. After driver was updated and the correct username and password were put in, it worked instantly!!

Thanks to both of you.
