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.

Evidently it is a connection issue, with your Mac. Other users have reported this issue being caused by apps/extensions like LittleSnitch, antivirus software, etc., and most likely something similar is at work for you and other affected users.

As @dialabrain suggested, test by booting into Safe Mode since that disables 3rd party extensions.

Start up your Mac in safe mode - Apple Support

If the connection works properly, then something you've installed previously is not fully compatible with Tahoe. Personally, my WiFi connection from my Mac running Tahoe is perfectly stable.
