As much as I'd love to visit the squad at apple support... I rolled it back to High Sierra and the Wifi is back.
I may give the update another try
Thank you for the support.
Got the error code: CNW008 NO WIFI NETWORKS DETECTED.
And there are plenty networks available and 3 other computers in my office on wifi.
