Welcome to Seven Forums,
If your computer was trouble free, have you tried a System Restore
and restore to a point when your Wi-Fi was working?
Boot to Safe Mode with Networking by restarting your computer, tapping F8 then selecting this option, disable your AV or Security software. Locate Device Manager, uninstall all the drivers with the !
symbol, restart your computer and let your Windows auto detect and reinstall all the drivers. See if this helps.
