MacOS Sequoia installed. Internet will randomly drop connection

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'm also seeing this problem.

Problem occurs on wifi and wired, on home and office internet connections.

Haven't found a solution yet.

My internet speeds are so slow now!

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!

The problem occurs on WIRED connections as well as wifi, and the settings you specified aren't present for the wired ethernet connection.

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.

I am running into the same issue.

I have multiple network extensions running which are pushed by our MDM. There is no way to remove them.

I tried to only disable them but this did not solve the network stability issues.

My MacBook Pro (M1) is struggling the most of the time with networking issues / drops.

In settings -> Details of Wifi -> Privacy -> Choose "Fixed" (even if it was off now its not working as expected so choose alternate option) and Save

Again go to the same option and choose "off" now.

After choosing "Off" - you should see a Privacy warning. Now reboot the Mac and problem is solved for me.

Same here, but I am now fighting a broken TimeMachine backup to my local NAS. Even deleting the sparse bundle and trying to recreate is not working.

Seems Apple is going the Microsoft way: fixing one issue and create three new ones.

Snitch is software to let you use pirated software.

This issue SHOULD have been FIXED BY APPLE!!!

Not us

Reflects the horrendous incompetent state of software developers

I have same problem with Viber. Found that the built-in Firewall orders to "Block incoming connections" for Viber and I can not change it (and some other). For some other services I can choose either to Block or Allow. How can this be fixed?

Similar issue with M3 MacBook Pro, I am able to join a Microsoft Teams meeting, but I become unresponsive and Teams thinks that it has lost the internet after about 30 seconds, but the internet is just fine, I can stream video at the same time. Tried turning off Private Wif-Fi, no luck.

I'm seeing the same problem and the only two apps impacted are Video conferencing (Teams, Zoom) and VMWare. I turned OFF the Wifi Mac privacy, and I even disabled wireless and went to only Ethernet and still happening. My Firewall is off, and I'm using Norton 360.
