MacOS Sequoia installed. Internet will randomly drop connection

Hi


I have a an M2 Max Macbook Pro with 32Gb of RAM. I installed MacOS Sequoia today. After installation, I started getting intermittent random internet connection/server busy messages on a black screen and this will go on for say 30 seconds or more and then randomly it will be back to normal again.


I have restarted the macbook pro. I have restarted the docking station. I have removed the ethernet cable connected and reconnected it after restarting the docking station. I still get the same problem showing up randomly.


Any suggestions?

I've had problems, both on my M2 MacBook Air and my iPhone 15. From what I can tell, these new OS releases interfere broadly with a number of applications, as well—in my case—my eero router. I can't use Proton VPN or Tailscale without losing connectivity completely.


What a disappointing mess of a release from Apple.

I am facing the same issue on a M3 MacBook Pro. It drives me mad when doing video calls via Zoom or Teams, every 30-60 seconds my internet connection drops for a few seconds. Happens both on WiFi and Ethernet. Other devices without Sequoia work fine.


I deleted the network configs, I flushed the DNS cache, I tried using different DNS servers, I deactivated virus protection software. Did not help.


Apple engineers, we need you!

Do not enable the built-in firewall. Do not run 3rd party "security" apps.


I mean, well, you can certainly do both of those if you want. It's your computer. But you're going to have to quit your job and spend a few quality months learning really low-level networking stuff and doing a lot of QA work for some really wealthy corporations. They will appreciate it, certainly. So will the engineers who haven't quit their jobs and are still being paid. You're doing their job for them. That's why they could go on vacation all summer to Costa Rica instead of debugging their products with the new Apple operating system. They know you'll do that work for them for free when they get back all tanned and relaxed.

I have found out that the issue does not happen, when connected via WiFi, private relay disabled, firewall disabled, private MacAddress disabled.

But as soon as I use a cabled connection, it does fail only when VideoCalls happen. In this case, the whole network stack fails for some seconds. (Running a ping to some host will just return errors, open ssh connection might disconnect). The connection is fine when no video call happens.

Slack actually freezes for some seconds, Teams brings a "network issue" randomly.


This is really annoying.

My "solution" is to use a WiFi instead of a cabled connection and live with less reliability and speed.


BTW, no difference if littlesnitch is enabled or disabled.

After lots and lots of testing and trying things, I found out the following:


  • WIFI works now with private static MacAddress
  • Private Relay is not an issue
  • LittleSnich works fine


Ethernet, on the other hand, had a totally new issue introduced here for me: I had to switch the Hardware settings from "Automatic" to "Manual". As soon as I switch on auto negotiation, problems re-occur.


Maybe that helps someone.
