I found that I have no wifi in Windows 10 after upgrading from Windows 7. This has been reported with a published fix, which did not work for me. I think because it applied to upgrades from Win 8.1. Has anyone else encountered this and solved it. My present plan is to remove the virtual machine and re-install Windows 7, test for wifi, and if present upgrade to Win 10, before installing any programs, then check for wifi again. If there is none, I'll just repeat and stop and Windows 7. Any better suggestions?
