I have four computers here, two running XP Pro, one running XP Media Center Edition and one running Windows 7 home (this one). I also signed up for a wireless 3G-modem (USB-connected). (Yes, I know that the USB port was really never made for LAN and I should have chosen an RJ45-model instead and so on...) The modem itself, a Huawei E1750, works flawlessly with all computers except for one, the one with the XP Media Center Edition on it, which also happens to be my gaming PC, thus I've installed tonnes of registry-changing games on it. The modem boots up, but always fails to connect to the 3G network (even the 2G network). It simply says: "Could'nt find a wireless connection." And goes back to idle mode. Could this be due to a pretty broken register? I will not run a registry-cleaner on the MCE-PC, because I've done so when the modem was faulty on the XP Pro's, and that jammed the modem up good. Luckily, those Pro OS's where easy to reinstall. The MCE-PC isn't. Might I get some advice on how to get the modem working with the MCE-PC?
