WiFi not working since build 25E5218f

I installed the latest build of Tahoe (25E5218f) yesterday on our test machine, an M1 Pro MacBook Pro and have been having a hard time getting my WiFi network to work. It's especially noticeable in Mail and Safari. Mail shows it can't connect to the designated server, and Safari simply can't connect to most sites. None of my other devices or computers are having problems, so I have to assume it's this last build that is the culprit. When I tether to my iPhone Air, everything pops back into place and I can access Mail and use Safari.

I've reported the problem with FBA, but wanted to know if anyone else is experiencing the same thing.

Having the same issue but with ethernet and WiFi. the connection is very very slow. All my other devices are fine but this one refuses to connect to internet. Outlook/teams/etc. only started after update, no one else in building is having an issue and no backend issue with my WiFi login is the issue either.

Same here. Both Ethernet and WiFi are not working. For me Safari and most native Apple apps are fine, but other apps like Outlook etc. are either very slow or not connecting at all. Rebooting into recovery mode seems to help but that is not ideal.

This is an issue we're aware of but we're not aware of any recommended workaround so far. If you find something that helps you avoid the issue, please share it with the community by posting it here.

I filed one here you go: FB22069080

Same here and this is really inconvenient and I am super frustrated. Come on Apple. You guys need to fix this. None of my browsers work except Safari. And my mail isn’t. The whole connection to the Internet is messed up.😡

Same problem. Since the update I can't get Firefox or Chrome to work, neither with WiFi nor via personal hotspot of my phone. Safari is working, but not fast. I left the Beta program because of this, but apparently there is no way to switch to the not-beta variant until there is a new version, which might be in a month?

Strangely it's just the web browsers, not other apps like for example WhatsApp.

Deleting and reinstalling Firefox & Chrome didn't help.

This seems to work for me: https://www.reddit.com/r/MacOSBeta/comments/1re3stp/comment/o7tuq0u/

26.4 beta 2 messed up network on my M1max mac studio. I couldn't acces internet properly, appart fomr googles services for some reasons, and it was significantly slower on Chrome and Firefox. Worked better on Safari, I could access more websites. In addition, I couldn't use my intranet at all (printer, home devices).

The weird part is when I activated my VPN things got better, except from the intranet which was still down.

The fix was to deactivate filters in settings>network>filters which in my case was Radio Signal. Now everything work, but I still need this software so I hope a fix will be released in the near future.
