If your wifi stops working, and the simple solutions (disconnect the reconnect, reboot, etc) don't help, you might need to delete the relevant settings files, and let the system rebuild them.
Reset Wifi Files in macOS 13...
Turn Wi-Fi OFF In Finder: click the "Go" menu and choose "Go To Folder" Enter the following file system path: /Library/Preferences/SystemConfiguration/ Remove these files: - com.apple.wifi.message-tracer.plist - NetworkInterfaces.plist, - com.apple.airport.preferences.plist - com.apple.network.eapolclient.configuration.plist - preferences.plist Restart the computer Toggle Wi-Fi back on
Note, you can move the files to be removed to another location, like the desktop, where they will be inactive. Then, if you need them active again, just move them back to the original location (replacing anything new which might have been created).
I usually write a blog post about once a week. The latest post can be viewed here: Deranged Rants: Many of them are totally feral, unhinged, and totally irrational. (posted 2024-11-13 at 17:55:14).
