I have a HUAWEI mobile broadband E173 dongle that is working perfectly on one computer (win 7 pro 32 bit) and is giving me a headache on another computer (win 7 pro 64 bit). I’ve downloaded the latest drivers for the dongle but no improvement. On the 64 bit computer the dongle installs the software automatically when plugged in and initializes correctly. But when trying to connect, most of the time it gets disconnect again within a minute stating that there is no device plugged in anymore. On the few occasions that it stays connected, the speed of the dongle is very poor. Also noticed that often the software is reporting a disconnect while in fact the connection stays on (for exemple a large download is still running and receiving data, the Windows network indicator is still good, but control software of the dongle reports a disconnect or a a device unplugged error.) I’m not experiencing any other problems with usb devices, so that doesn’t seem to be the problem to me. Any help would be greatly appreciated.
