Update: This is a bug that has been recently fixed with the release of macOS Ventura 13.1.

I have a MacBook Pro M1 14" and have it connected to a 5Ghz WiFi.

I can usually use WiFi and Bluetooth together (i.e. I have AirPods Pro and a mouse connected). Certain events, though, will slow down the Wifi speeds to a crawl and it will often only go back to normal after a reboot:

  • waking up an another nearby device like an iPhone or an iPad (not the watch)
  • any notification (even if hidden by DND focus)
  • (re-)connecting a bluetooth device, i.e. temporarily taking out one AirPod and putting it back in.

The problem is most apparent when playing games over streaming services like GeforceNow. They become immediately unusable.

I have found a temporary fix which I will add as an answer, but I am very much open to better solutions.

The problem went away, when I disabled the virtual network interface for the Apple Wireless Direct Link protocol in the terminal:

sudo ifconfig awdl0 down

After I'm done with my gaming session, I re-enable the interface with

sudo ifconfig awdl0 up

People seem to have had issues with AWDL for some time. The most recent I could find was this comment in the Macrumors forum.
