No internet on MacBook Air M1 after macOS Tahoe 26.0.1 update

Hi guys. I updated to Tahoe as soon as the update was released and i had no issues till today. So today, i installed 26.0.1 and since the restart my WIFI and ethernet is not working. I don't have any internet filters like snitch, disabled ad guard, turned on firewall, made the wifi forget and rejoin, delete the system config preferences but nothing is working. I know it's not a connection issue since my WIFI works fine on my ipad and the iphone. Guys please help me out here.

My wife’s M1 Air had that problem. I fixed hers by going into the terminal and entering sudo ifconfig en0 down and then sudo ifconfig en0 up.

Does it work in Safe Mode?

Just to add, I would try it without the Ethernet adapter connected.

Yesterday I have updated to Tahoe 26.01 on my Macbook Pro M1 Max, and I have the same problem. I am connected to wifi router, but no internet whatsoever. Of course my other devices connected to the router works perfectly like before, but not the newly updated mac.

I've tried to run network diagnostics (it told me to contact Apple Support, since there's no internet connection :D).

Anyone found the fix?
