Ventura 13.3.1 Update causes WiFi fail

I can't connect to wifi after updating to Ventura 13.3.1. Four other devices are connected to WiFi successfully but my MBPro fails after yesterday’s update to Ventura 13.3.1. When initially attempting to connect to a known network it would cycle connected then disconnected. I forgot the network and attempted to connect again and it now fails completely and show "The Wi-Fi network ... could not be joined". Nothing else has changed since I was able to connect to the network. I ran the diagnostics tool but it was unable to find the problem. I cleared the DNS cache, renewed the DHCP lease, and ensured the IPv6 configuration is set to “automatic.” I’ve restarted the machine. Nothing is working to resolve this problem and I am forced to hotspot from my phone as a temporary solution. Help, please!!?

I'm not sure if this has actually fixed it. However so far I'm seeing better results, including routable IPv4 on my Mac. I ran though these instructions about dropping the networking plist files which results in the OS having to rebuild them from scratch. I didn't both to compare before and after, I just dumped the old ones and let it do something new. So far no flickering and full networking has been function:


  1. Quit out of all active apps on the Mac, including System Settings
  2. Turn Wi-Fi OFF by going to the wi-fi menu bar (or Control Center) and toggling the wi-fi switch to the off position
  3. Open Finder in macOS, then go to “Go” menu and choose “Go To Folder”
  4. Enter the following file system path:
  5. /Library/Preferences/SystemConfiguration/
  6. Hit return to jump to that location, now locate and select the following files in that SystemConfiguration folder
  7. com.apple.wifi.message-tracer.plist
  8. NetworkInterfaces.plist
  9. com.apple.airport.preferences.plist
  10. com.apple.network.eapolclient.configuration.plist
  11. preferences.plist
  12. Backup the files and then delete them.
  13. Reboot your mac
  14. For me, wifi turned on and it remembered my SSID + Password, reconnected, all seems good so far.


It's been a few hours but so far so good.

I have the same issue with MacBook Pro 14", Nov 2023. Work laptop that came with Sonoma. We believe the issue is related to my profile. I created a local profile and I now have a persistent network connection. We will be deleting my profile and creating a new one.


BUT, I just updated my lady's MacBook Pro 13" 2017 to Ventura. I was logged in as her. After restart, I can ping pepsi.com from Terminal but no other apps have network. BUT, I can log out and log in as me (I have my own local profile on her machine) and I have internet no problem without restarting. I tried all the steps above, same. No internet for her, solid internet for me. Same machine.
