26.2 update broke all network-connections

Can't connect to any network drive or shares, after updating to 26.2.

And can´t connect to my timemachine back-up via WiFi or ethernet anymore.

I'm I the only one?

Mac mini, macOS 26.2

As soon as I went into wireless settings and turned off “Limit IP address tracking” the problem resolved. So I now have a choice….working Internet or improved privacy. Sharing to help the Apple engineers figure this out for Mac Tahoe 26.3….

(Based on another thread not yet fully resolved…) Do you (not) have two-factor authentication enabled?

Mine ended up being a DNS issue with a custom DNS I had set to my wifi interface.

Wifi connectivity fixed by “forgetting” WiFi network and then reconnect.

But it looses access again from time to time.

Not a good stabel fix. Really don’t know why this happens.

Same issue. I installed the Tahoe 26.2 update and suddenly my Mac Studio lost wireless network connectivity. Every other device on my network is fine. Just not the Mac I installed Tahoe 26.2 on. Come on, Apple, do you not test this stuff? I read reports on the web of needing to restart the router, reboot the Mac, etc etc. But people shouldn’t have to do that. Apple seems to get worse every year. It drives me nuts.

I've got the same issue. Other devices on my network work fine and my machine took the update over the weekend.

Did you find a solution?

Reinstalling Tahoe did not work. Still can’t mount any networkdrives. Or connect to my NAS via the browser.

An endemic issue with macOS 26.2 would usually have reports in the forums and some big 🤬 threads, so probably something local.

If you are running Samba, make certain your servers are not running Samba 4.22.

Either older, or 4.23.4 or later, 4.22.6 or later, if I read the release notes correctly.

Check over at the UniFi forums, too. Maybe this?

Right now trying to reinstall Tahoe, via recovery-mode. I’ll get back if it works or not.
