I have been having issues with wifi since Catalina and even after upgrading to Big Sur it's not helping. I did try the steps outlined in the thread above they work temporarily. Wifi on my other devices works just fine. I re-imaged my mac a couple times and also got a replacement from work but this issue seems persistent. VPN or No-vpn doesn't make much of a difference. Worst customer experience ever Apple.
