Got my USB modem dongle 1 month ago. When I connected it to my Win7 notebook, it does not seem to detect the modem but shown a removable storage that contained the Mobile Broadband Modem softwares and drivers.
After installing the software, the removable storage disappeared. Huawei E1550 USB 3G Modem was nowhere detected. Mobile Broadband Modem software prompted that the device was not connected. Try restarting Windows, but still no E1550 found.
I give-up and use the simcard on my Nexus One.
Yesterday, I tried googling for solutions, tried upgrading (I end up downgrading the firmware), but Win7 still can’t find the modem. Use my WinXP VMWare to downgrade the firmware as it detected the modem. Via Starhub’s website, it is confirmed that these firmwares supports Win7.
After getting pieces of tips here and there, today I decided to uninstall the software and driver. Put the installation software on a harddisk drive and installed it without the dongle inserted.
Shutdown my notebook and attached the dongle to the USB slot and re-powered my notebook. Viola, it started to detect the modem!
I’m getting the 3G Application Interface and 3G PC UI Interface! Load Mobile Broadband Modem and there is no more prompting of unavailable device.
Tried ways to share this internet via Access Point, but my notebook Wireless Network Connection adapter does not support Access Point, but only Ad-Hoc network.
No choice, now I had to find a portable 3G wifi router.
