I had to uninstall and reinstall Window 10 using a Microsoft installation disc. I'm installing to a SEPARATE DRIVE. Installation completed. Its CONFIGURATION that's not completing. It quickly hung up on a page that requires Windows 10 RECOGNIZE my INTERNET SERVICE and CONNECT TO IT. It will not. I have Windows 7 on another drive and there are no issues there. It's only windows 10 for some reason. My provider is AT&T. The modem is a BGW210, for what that's worth. AT&T wanted to run diagnostics, but they cannot because it's only on Windows 10 to which I will not connect. The modem light is GREEN, while the modem CARD LIGHT is YELLOW and continuously FLASHING. Does that mean anything aside from not wishing to complete the connection? I have the 64 BIT version of Windows 7 and 10 if that helps. I may upgrade to Windows 11 later, however i have to get Windows 10 fully running first, so I have an alternative to Windows 7 once I uninstall it. PLEASE HELP
