Slow wifi issues on Mac Mini M2 Pro post Sonoma update

This is the reason. On Sonoma you need to turn off one settings in network. I have tried on different networks and this is the reason why MacBook is slow on wifi. Attaching images so you can find it easier. Basically, go to network settings for the connection you are currently on, and turn off Limit IP address tracking. I don't know if there is a way to turn it of for all the networks at once.

I combed the entire internet for "OCLP update Sonoma wifi slow performance" and nothing worked!

Until I hit this simple trick to "Limit the IP tracking off". Worked like a charm!

Speed Test went up from 75Mbps to 600Mbps!! Thank so much! This simple solution deserves hundreds of upvotes.

Where can I send you a bottle of beer? :-)

This is really frustrating! Since updating to Sonoma on my Mac Mini M2 Pro, my wifi has slowed don dramatically and even stops at times. I've never experienced this before. All other non-Sonoma devices (Windows, Google Chromecast and Amazon Echo) are working normally. It's only my Apple device that has the problem. I've tried everything recommended on the Macpaw site, (DNS, DHCP renewal, router off/on, wifi offf/on) and have also uninstalled VPN,

Good work trouble shooting so far 👍

and network filters and disabled my antivirus.

Any Third Party Applications that will interfere with the normal operation of the OS,  is an invitation for disaster.

Any of the below should be removed as per Developers Instructions 

1 - Disk Cleaner 

2  - Third Party Security Software 

The The Built in Security  is all that is required.

Mac app security enhancements - Apple Support (CA)

Security. Built right in

The Operating System resides in a Sealed and Read Only Volume that can not be opened by the User nor by Third Party Applications.

Q - " is there a way of temporarily reverting back to MacOS 13? "

A - You may not need to explore that option by removing the Third Party Security Software

There are no known Windows-like Viruses in the wild that self replicate and affect macOS, because of the underling UNIX  Foundation and Permission Limitation

Get rid of macpaw apps, and you'd be alright. They are selling fear, as usual to sell junk ware. MacOS can do well without them.

After all, it was a VPN issue. The program was closed, but it was still turned on, although it was not visible

I am having the same issue. Since I updated, the wifi is terrible. No other device is have an issue. I have a Mac Mini M2 Pro. Even loading youtube on Chrome, it takes like 20 sec to load. Apple please fix this, its embarrassing.

Apple can fix what Apple Controls

What they can not control / fix is what third part software the user has installed on the computer

FYI, M2 Mac Mini, M2 MBA and M1 Mac Mini all connecting to Fibre Optic connection via wifi 5 gHz and 6 gHz connections.

Getting average of 540 Up / 565 down speeds

Go figure

I have this exact issue - it only started yesterday for me and I thought it was the hotel wifi - every other wifi device works great.

I have nothing else on my laptop if a security nature at all.

im pretty sure there was not an update yesterday.

Ive tried everything - hotspots the works - running a16inch MacBook Pro with sonoma M1 Max chip

I have exactly the same problem on MacBook Pro 14 M1 Max OS Sonoma

This happens in just a couple of days. There is no third-party software, I even closed all applications. I tried all the channels on my router, tried different routers. The iPhone easily gives out 300 MB, but the MacBook either 20, then 100, or does not work at all.

I have a M3 MacBook Pro but it is pretty much useless as network download/copy speeds are slower than molasses in winter. Any hope of resolution soon?

Have tried the setting above but has made no difference whatsoever!

I am running latest version of Sonoma, no VPN!

Glad it helped you. Interestingly, apple bot/support blocked my answer two times before I manage to post it. The reason was something like giving personal information ( I believe somewhere my username on computer was visible).

Those "apple consultants" are usually not of help :D

Enjoy your speed, and have a beer on my behalf! <3

I didn't realize this was slowing down my connection. More than doubled my download speed - thanks!

You are welcome :)
