Upgrade Sonoma 14.1.1. Problem with Internet connection

My VPN “Wireguard” set up was running. Turned it off and now internet (both Ethernet & WiFi) are working. Thx.

Thanks a lot for your response! :) It was the Little Snitch that was causing the trouble. Once I disabled via the

System Settings -> Network -> VPNs and Filters it worked directly :) (Before I was trying to disabled it the application itself and didnt work).

It would be interesting to find out why these VPNs trouble with Mac's internet connection. These VPNs in trying to hide the router IP address, simply cuts off the connection to the router itself from within.

I use ProtonVPN. I can choose different protocols incl the "Smart" choise which will automatically select the most efficient protocol for a given connection. I saw that when on "Smart" the WireGuard protocol was chosen. In this case I got a connection but after a short while the connection was broken. I turned of Little Snitch and NetBarrier one-by-one. That didn't change a thing.

My solution was to force the protocol to be IKEV2. Then the connection would not be cut off and be fast and reliable. Turning on Little Snitch and NetBarrier did not break the connection.

I only had this problem on one of my Mac's. On the 3 other ones the WireGuard protocol is working OK.

Reset your router.

Reset your router.

I have exactly the same issue. After the upgrade internet broke. It recieves an IP address, the gateway and DNS server, so DHCP works, but for pinging even the gateway it says "no route to host" and 0 packets reaching the gateway. Also it cannot ping the ip of the laptop itself (the one that was recieved by the DHCP server)! I tried also on different access points but always same issue. I noticed that turning off everything related to wireless like bluetooth fixes temporarily the internet issue, so I could ping an extrnal IP and resolve DNS names, but the browser and the upgrade application says no internet. I tried also with a cable and it seems that only internet via the commandline work. It's obvious that Sonoma was not tested properly before the realease. Anyways, I hope there is a fix for that soon.

System Settings> Time and Date> turn off automatic updates and then manually set your date and time. Re-check your internet

For my case It looks that is not related to Little Snitch. Turning off all the wifi related stuff worked for a while and when I turned on bluetooth at the same time the issue appeared again. :(

Get rid of all kinds of Little Snitches, your Mac will thank you.

And, you'd stop having all kinds of headaches...👌

How do you turn off VPN?

You don't need any VPNs, antivirus apps or any modifier apps. That's one of the reasons you buy a Mac. So, when you add those 3rd party useless apps, you have a problem.😏

Sonoma 14.1.1. I have a similar issue but the system time reverts to 9th Aug 2023 around 1200 and and will not accept automatic time changing.

mail works i&o but picture content will not load in Safari.

any thoughts please

VPN as in a part of little snitch?

You have to take a decision, whether you want your internet connection to work without fail, or live with those internet connection failings using 3rd party apps. If you are worried that some websites you visit might try to pull information from your computer, don't connect to them. Safari is quite good at keeping you safe, that is, if you want that. Safari settings > look at tabs Security, Privacy and Websites for example.
