Completely clean install of Odin. Wifi worked, but figured if there is an update, should get it. Updated bcmwl-kernel-source. Wifi no longer visible I tried un-installing bcmwl, no change.
Try the Linux Kernel Headers install process outlined on Github / elementary / appcenter: https://github.com/elementary/appcenter/issues/1603#issue-965454894
Edit: this process worked for me until restarting the computer. On restart wi-fi is no longer visible in network settings.
