to all who have taken the time and effort to read my post....thank you. I was certain last night that I would be taking my Macbook into the Apple Store 7 hours drive from my location. I last used it with an Ethernet connection last night. I am up eary and I just turned it on and the WiFi is working again. ?? ???? ?? I have no idea.
Thanks to the firt person who replied especially and gave some suggestions. I am going to take it in to an Apple store in Toronto soon and leave it with them fo a couple of days. (I even deleted my VPN and it is a paid suscription).
