Oculus air link connects then disconnects

If you are using Airlink, please refer to the following link for troubleshooting.
Additionally, you can try the following steps to resolve the issue.
  1. Disable Nvidia GeForce Experience In-game Overlay
If you are using an Nvidia graphics card with Geforce Experience installed, go ahead and disable the in-game overlay option. The has caused numerous unexpected lagging, black screen, and also disconnect issues when used with Oculus Link.
To disable the feature, open Geforce Experience, click on the cogwheel “Settings” option and toggle the “In-game overlay” option to disabled.
  1. Force Using Dedicated GPU (Laptop)
If you are a laptop user, your Oculus Air Link issues might be caused by the fact that the system is using the integrated graphics card (GPU) for Oculus processes (instead of the more powerful dedicated GPU).
The Oculus files/processes that we are interested in are the following:
  • C:Program FilesOculusSupportoculus-runtimeOVRRedir.exe
  • C:Program FilesOculusSupportoculus-runtimeOVRServer_x64.exe
  • C:Program FilesOculusSupportoculus-runtimeOVRServiceLauncher.exe
  • C:Program FilesOculusSupportoculus-clientOculusClient.exe
To force Windows to use your PC’s dedicated GPU for these Oculus processes:
  • Press Windows Key and search for “Graphics Settings
  • Click “Browse” and add all of the above files.
  • For each file added, click on “Options
  • Select “High performance” mode from the settings
  • Save and restart your laptop
  • After restarting, try launching the Oculus Air Link connection again and see if the problems are gone.
  1. Turn Everything Off and Back On Again
If you have verified that your PC has enough computing power to run VR games, the next step is very simple: just turn everything off and then back on again.
  • Disable Quest Link (Settings → System → Quest Link)
  • Restart your PC
  • Restart your headset
  • Enable Quest Link again
  • Launch Air Link Connection
With software, it’s quite often the case that starting from a “blank sheet” helps with a variety of different problems. This is actually my go-to solution whenever I am having trouble connecting to my PC and establishing an Air Link connection.
  1. Disable Firewall / Antivirus (Temporarily)
I am going to start with the fact that disabling your firewall and/or antivirus is generally almost never a good idea. That being said, for debugging your Air Link connectivity issues, I am going to ask you to do exactly that (temporarily)
Third-party Antivirus software (for example McAfee, Avast, and others) have been known to often cause issues. For this reason, disable your Firewall as well as Antivirus software and check whether you are now able to establish an Air Link connection.
If you were now successful in your attempt, determine which software was causing the connection problem and re-enable both of them. Use google and try to find a permanent solution (adding exceptions, etc) for your problem where both Antivirus and Firewall remain enabled on your PC!
When adding exceptions, the following applications should be added to the whitelist:
  • C:Program FilesOculusSupportoculus-clientOculusClient.exe
  • C:Program FilesOculusSupportoculus-runtimeOVRRedir.exe
  • C:Program FilesOculusSupportoculus-runtimeOVRServer_x64.exe
  • C:Program FilesOculusSupportoculus-runtimeOVRServiceLauncher.exe
Note! Oculus states in their support documentation that port 5669 (TCP) must be open. Make sure your firewall is not blocking it!
If disabling the firewall and antivirus had no effect on your Air Link connection then leave them enabled and proceed to the next steps.
  1. Update / Downgrade Graphics Drivers
In 99% of scenarios, you want to have the latest graphics card drivers installed when using Oculus Link. So if you are currently having disconnects when using the Oculus Link connection, make sure that your GPU drivers are up to date.
Do keep in mind, however, that there have been problems both for AMD and NVidia graphics cards with certain driver releases. If you updated your GPU drivers recently and started having problems afterward, it might be a good idea to roll back the drivers to the previous release.
