I have recently upgraded my laptop from Windows Vista 32-bit to Windows 7 Home Premium. I have performed the following steps to get my Huawei E169 3G modem working in Windows 7 again.
- Uninstall the SingTel Broadband on Mobile software and unplug your 3G modem from your PC/laptop
- Download this patch from Huawei (Local Mirror), extract the setup file and run it.
- Reboot your PC/laptop
- Plug back your 3G modem. Wait for the SingTel CD drive to appear in your "My Computer"
- Install the SingTel Broadband on Mobile software again. Your 3G modem should be automatically be detected after the software has been installed.
PS. SingTel Broadband on Mobile web site has some firmwares and Windows 7 fixes for Huawei E169 modem. But these softwares keep giving some code 2 errors indicating that I do not have administrator permission or the data card is being used by other software on the PC/laptop. Well, in all cases, I have gotten my 3G modem working without these "upgrades". Thank goodness.
