Windows does not detect any modems anymore[HSPA]

By an accident i uninstalled my Connect manager (ZTE). but when i re-install it the virtual CD drive is detected but it does not detect the drivers. When i direct to the folder containing the relevant drivers(.sys files) still it doesnt detect.

Then i tried a modem of a different brand Huawei the same problem presists As i understand it is not a device(brand) driver specific issue as it does not detect modem(dongles) of any brand. when i plugged in a different USB device(a pen drive) the driver is detected and it works perfectly.

Please help me with the issue i have tried system restore but it doesnt work. I want a repair that works without re-installing windows

[Edit] Uninstalling drivers/ software and reinstalling doesnt work.
the issue does not deal with the registry

Unplug the modems/dongles, uninstall all software/drivers, restart, use USB Oblivion, restart once more and try any one dongle. Let us know if it worked.

Tried it didnt work.. I am sure that the issue does not deal with the registry as i have tried your method and system restore in an earlier instance – Shenal Silva – 2012-11-25T04:13:32.043

If you have now all the software installed as before you uninstalled it, you may be able to rollback to a system restore point in which everything worked correctly. – harrymc – 2012-12-13T19:03:57.473

Tried it mate it didn't work – Shenal Silva – 2012-12-13T20:56:40.190

It has to work, unless : (1) should rollback further, or (2) hardware problem. – harrymc – 2012-12-14T08:14:35.840

Problem is not with the driver , or the hardware for that matter as i have tried several brands of modems its a configuration file issue as i see – Shenal Silva – 2012-12-15T09:39:15.053

As you say that it is not driver or hardware, that leaves only Windows. However, as you have not specified the modem's hardware connection, hardware still remains a possibility (for USB it is easy enough to check if the socket works by using an external disk or key).

For fixing Windows without a complete reinstallation, I can suggest :

  • Windows Update including optional updates
  • sfc /scannow
  • Extensive virus scans by several well-known anti-virus products (just to be sure)
  • (The method that worked for this problem) If all fails : repair install, which only refreshes Windows and without doing a complete installation, so leaving intact all installed applications (you need for that an installation DVD of the same service-pack level as your current installation).

Make sure you have complete backups before starting.

Well i am going to try your suggestions. what info do you require of the modem's hardware connection?. It is a ZTE MF110 usb modem. and all the other modems that i have tried are also usb modems – Shenal Silva – 2012-12-16T09:23:50.020

Have you checked that this usb socket works? – harrymc – 2012-12-16T11:19:38.093

If system restore and even repair install didn't manage to get modems working on your computer, the only suggestion I have left is to format the disk using slow format and reinstall Windows and everything from scratch. – harrymc – 2012-12-20T15:16:24.137

the repair install method worked thank you :) – Shenal Silva – 2013-01-07T16:26:19.197
