Resolved - Quest Airlink lags and stutters after V54 update.

[v1rtualv0id]

Been using Quest pro with airlink for 4 months now without any issues whatsoever.

After the headset was updated to V54 I'm having headset lag/connection issues on airlink.

Screen is stuttery at times when moving in my playspace or moving my head, the image gets laggy, choppy and black frames appear on the side of the screen oposite to where I'm moving my head.

Image quality has degraded significantly with lots of "artifacts".

This makes casual games like VR chat hard to play due to constant lag and stutter, games like Beat Saber are impossible to play.

I havent changed a single thing in my playspace nor my setup, router config is the same as when it was working, PC is the same, no update has been applied to any of this. 

Any advice would be much appreciated as Im lost on what to do.

Just in case

Specs 

CPU I9 12900k

32GB Ram

GPU: NVIDIA RTX 3080TI

Router: TP-link AX1500 Wifi 6 dedicated just to the headset.

No. Did you even read the first page of comments? Sound you're just copy pasting a "Did you try turning your PC on & off again."
This is a QUEST ISSUE with V54, not User Error.
Oculus Support cannot help us, only a Quest update can.

The same problem happened to me.
My quest pro was updated to v54 and the problem started as soon as it was updated.
After many tests, if I turn my head or walk sideways, the bitrate drops to 10 and the latency rises.
It's so bad that it's impossible to play the game.
If it doesn't move, the frame recovers, but when it starts to move big, the problem starts again.
Connecting with the Virtual Desktop app shows exactly the same symptoms.
To sum up, it's a symptom where the headset and router don't seem to communicate properly when I move big.

Yeah I spent half a day doing troubleshooting with no effect.

To answer the first three questions:

Yes, it did work previously just fine up until recently

Nothing has changed with my pc setup itself, has been the same and has not changed

Trouble shooting started first with the simple stuff of restarting everything, pc and oculus itself and the app.

tried shutting everything down, different ports, flipped the link cable and reconnect with the 3.0 usb, tried both ends  in headset and into pc, then i went on to my settings to see if anything was preventing the link cable from connecting cause what keeps happening is when i plug in my link cable, it registers, asks to save files on headset and then i enable and when it tries to load up (three dot loading screen) it just ends up disconnecting after 5 to 10 seconds or a lil longer then that. The only notable thing that i can pin point the issue is that the oculus app is version 53.0.0.105.132 and my headset is version 53.0.0.137.132, thing is i tried updating everything, repairing the oculus app multiple times, uninstalled it, reinstalled it and did a factory reset on my headset to try and see if i could align the version,  but it seems like i can't match the version with each other and I'm just stuck with two different versions.

I have some information to add.
I also have Quest 2, which I didn't use often.
It's v53 and just confirmed there's nothing wrong with the airlink.
In summary, connecting Quest Pro v54 causes problems and Quest 2 v53 is normal.

Dropping in just to say "same". Having frequent connectivity issues with the Quest Pro on v54. Crashed out four times across three hours during a Monday session. Not very good.

Hey guys! Just checking in since this seems to be something that's happened on v54 now. If you've tried any relevant troubleshooting (see below) I suggest holding out a bit since we'll be trying to update this thread as much as we can. Along with that, please be sure to submit bug reports for anything you're experiencing. Thank you!

Troubleshooting:

1. Reboot headset:
   1. Power it off > Hold Power button and Volume Down button > Highlight Boot Device and press the Power Button.
2. Factory reset (done through previous steps as well)
3. Checking Windows updates 
4. Checking Air Link Best practices
5. Here are some other Link troubleshooting steps as well

Edit 6/8/23 - We have checked in with the engineers and I can confirm they're currently working on it. Hopefully we get a fix soon (Marking this as the solution so everyone can see it easier)

Edit 6/11/23 - Some users have reported opting into PTC v55 seems to work. I'll still be checking in every now and then, however.

Edit 6/19/23 - No updates yet, please continue to submit bug reports and whatnot. Thank you!

@Raycid,If you believe the application requires an update, try manually updating the Oculus PC app on your computer by opening the Oculus PC software on your computer > library > updates; any changes should be in this section of the application. This, however, may not be the case. If you haven't already, try updating the drivers on your computer; if you have, we may need to remove and install them again for good measure. Try the following and let us know if this helps any: 

• Disconnect the Link cable from the computer
• Uninstall the graphics driver. This should be done through the control panel, as uninstalling a driver through the device manager may not remove all files or applications associated with that driver.
  • In the search box on the taskbar, type Control Panel and select it from the results.
  • Select Programs > Programs and Features.
  • Scroll down the programs list to locate the graphics driver.
  • When located, right-click on it and select Uninstall or Uninstall/Change.
  • Follow the directions on the screen.
• Restart the computer. Without a graphics driver installed, Windows will default to a standard VGA driver, and the display resolution will likely be lower than what it was previously. This is normal.
• Download the latest driver for your graphics card from the manufacturer's website
  • Nvidia: Download the latest drivers from the GeForce website directly at Nvidia Drivers
  • AMD: Download the latest drivers from the AMD website directly at AMD Drivers.
• Restart the computer again.
• Reconnect the Link cable and test to see if the problem has been resolved.

If this does not solve the issue, please contact us again; we look forward to hearing from you.
