Just upgraded to W10 but now I can't connect to my home network. Ran diagnostic... nothing changed, reset modem also no joy, was my wireless network adapter improperly configured? Other computer on network works fine, and my laptop connects to other networks (public) just as before. I did the upgrade while connected to a network other than my home one. Can I restore back to W8.1 then reinstall the W10 upgrade while connected to my home network? Or was the W10 upgrade a one shot deal and now I would have to pay for the second install? If so then I need to figure out the connection issue. Have read about uninstalling the wireless network adapter and restarting the laptop and letting windows auto detect and reinstall the adapter but unsure. I know enough to be dangerous. Any other suggestions.
