Sonoma 14.0 update internet problems

I have a MacBook Air and last night I did the Sonoma 14.0 update. Once it finished, my MacBook no longer gets the internet. It connects to Wi-Fi, but there’s no internet. I know it isn’t my router since we have other devices connected to it. I tried resetting the router anyway, which didn’t work. I tried rebooting the computer, “forgetting” the Wi-Fi and reconnecting, I changed the DNS IP address to 8.8.8.8, I renewed the DHCP lease, I checked the date and time settings. Nothing is working. I tried connecting to a different Wi-Fi and am having the same issues. It won’t let me use the internet off my hotspot either. Please help.

MacBook Air 13″, macOS 14.0

I spoke with support for 2 hours and we finally figured out it was my antivirus software (something my company installed) preventing it. After uninstalling it, the problem was fixed.

The update to Sonoma creates big issues connecting to the internet, even though the machine show a solid connection. After consuming much time getting rid of everything I am supposed to have on this machine, including filters and VPN and using activity monitor to force quit apps, the Mac suddenly connected to the internet, but only on the office network. I am left without any internet when I am mobile and joining other networks. There really is no reason why any software that protects our machines should be removed after this update. Again, after removing anti-virus, Sonoma still does not connect [before removing anti-virus, it suddenly connected to one network, but rejects all others outside the office]. Obviously there's some security routine built into Sonoma that is causing these issues. Apple needs to provide an update solution immediately. Not being able to use my computer mobile at work is a nightmare.

Hi, I am using Sonoma on a new M2 BacBook Air. I am quite familiar with the Settings area of Macs, but for the life of me, I cannot find the "Network Filters" that you wrote about after I go into "Network." Are screenshots allowed here?


I just got my machine, and more than once I have experienced the wi-fi connection dropping, and as well my ethernet/PPPoE connection dropping. They are different services from different ISPs, and both are 100% stable on my other Macs.


I have no VPN installed. Do have one adblocker installed.


I feel that it must be something that Sonoma is doing...

Hi Guys,

I too encountered this issue which I only resolved this morning after spending 6 hours applying suggested fixes from this post and a few others.


Backdrop: I failed to keep my 2014 Macbook AIr updated. My last OS Upgrade was Big Sur. I eventually realized there was no quick workaround...I created a boot install using Open Core. https://dortania.github.io/OpenCore-Legacy-Patcher/START.html. The upgrade to "Monterey" completed early last evening. Thereafter, I had the option to upgrade to "Sonoma" via the update method. Once I rebooted the WiFI was kaput. I tried many of the suggestions here before I even found this post:

rebooting in Safe Mode a zillion times

manually adding my WI-FI network and turning it off and on

trying to use my hotspot

shutting off my firewall

Removing the VPN


etc, etc, until 3AM...

This morning I decided to run this clean job using Open Core GUI, then rebooted and Walla!
