No internet after update to Sonoma

Little snitch turned OFF did the trick. Must be outdated version (looks like needs 5.7.1).

Had the same problem, found the issue to be Surfshark, even though not running. Changed protocol from wireguard to openvpn.

Try restarting in safe mode followed by a normal restart.

Sonoma upgrade messed up my Network locations. I had to remove every single Network location and start over, I could not even start Wi-Fi it was greyed out for some reason.

This is it! Disabled little snitch and everything went back to normal.

I finally got rid of this issue, cause for me was the new Microsoft Teams. After switching back to the now so called classic variant, I had no more connection drop outs.

This thread illustrates why it is impossible to answer a question like "it does not work" without details like "did rebooting related devices or safe-mode help, any 3rd party software and hardware, virus apps, VPN, cleaners, EtreCheck report", etc.

Hi Paul,

How are you connecting to your network, Ethernet/wired or WiFi/wireless? After upgrading to Sonoma, I'm unable to connect using Ethernet/wired, as per: Ethernet (through Thunderbolt Display) no… - Apple Community

Kind regards,

Adam

Sonoma system settings Network Other Services Ethernet has red dot not connected

I had the same issue… I was able to fix it with sibling my little snitch ;(

This is the same for me summersnake. Only started happening today. I lost connectivity 3 times today. Wifi and LAN are green in the network settings but no connectivity. I’m in my home office using 1G LAN line. I try to hotspot off my iPhone and Mac won’t connect. Reboot is the only thing that fixes it.

There is an update for AVG. Follow the instructions on their Website and everything will be back to normal.

Thanks for your help, guys!

System settings sees the wifi.

Chrome, Safiri, Feedback assistant, App Store, Little Snitch (not compatible) updater

Everything thinks that they are off line except Systems setting Wi-Fi

Switched to personal hot spot using this phone. Same. ¯\_(ツ)_/¯

The issue is intermittent on my mac. After a reboot, everything is fine. Then after some time, certain apps will stop being able to connect (typically Chrome, Outlook, Slack). Reboot fixes it again. Have had no issues with Zoom, but I can be on a call and the other apps stop connecting. I'll try some of the filter suggestions provided.

NB: I'm on a corporate network, Cisco VPN, with Zscaler.

I have had no trouble with Cisco AnyConnect. Of course with it ON, I could not connect to Internet, only to those sites at work I was allowed to. After disconnecting VPN Internet was OK without rebooting. But it has been almost two years since I last used that.
