[Solved] Slow Wifi after Ventura upgrade

This has been really annoying. I'm an expert Mac user, been using Macs for 25 years and am an IT guy, but I could not find a fix for this.

Every day or two, or sometimes multiple times in a day, my Mac would slow down greatly on my wifi, or sometimes stop accessing the Internet. Yet my iPad Pro, iPhone, etc. everything else was still running 360Mbps download speed, while the Mac was limited to maybe 40Mbps on the same network, same location. Nothing would help except a reboot, which is very inconvenient.

Hardware: 2020 M1 MacBook Pro 13", 2021 M1 iPad Pro 12.9", iPhone 13 Pro Max.

I suspected Network filters and disabled those. Cleared DNS cache. And many other things, too many to list. All the usual suspects, short of wiping and reinstalling from scratch.

Then I ran across this:

Recent Apple updates leading to WiFi issues & an interim solution

https://www.meter.com/mac-osx-awdl-psa

an excerpt:

"Macbooks use a WiFi interface called AWDL (Apple Wireless Direct Link) for features like AirDrop and AirPlay. Having AWDL on may cause your WiFi connection to periodically reset. Although these issues can manifest in various ways, the underlying issue is the same: throughput and speeds drop, devices get disconnected randomly, and fail to rejoin the network."

I implemented the scripts on this page and my speed immediately went from 40Mbps download (when it had worked at all before) back up to 360Mbps.

It adds it to launch control so it starts when your Mac starts, and then runs in the background to keep the AWDL interface off.

The only downside? This *may* disable Airplay and Airdrop.

I don't use Airdrop on my Mac.

I was able to use Airplay, but I suspect it brings the AWDL interface online to do this, but I'm not sure. Again, I don't really need Airplay on the Mac.

ANYWAY, this fixed it for me!

When Apple addresses this, I'll disable the script but in the meantime, I'm back to full speed 😎
