Airlink=Why has everything started lagging?

Level 2

About 5 months ago or so, I was playing games just fine over my 5ghz router. Then all of the sudden, (maybe 3 months ago?), everything started lagging. I get black corners and things stretching out weirdly, delays, audio stutter etc.


I have checked my router and the only thing that is using the 5ghz network is the oculus quest 2. All other stuff in the house is either wired or using 2.5ghz


What could be wrong? I *could* get a wifi 6 router, but since it was working fine earlier, what has happened?

Is this a widespread issue? Or just me?

I mean, the neighbours could have gotten a new wifi system, and therefore affecting my system... but still, I' standing about 3 meters from the router and still stuff is laggy.

I have 1000mbps internet in the house and the headset is using 5ghz i should theoretically be fine.

So a new wifi 6 router or is this somehow an oculus software problem? (just did a clean install adter banging my head against the wall).

And by the way, my oculus debug tool is looking like this:


Should be good, right?

One possibility would be network interference--a neighbour might be on the same channel as you on their 5 GHz network. You could go into your router settings and check for channel congestion, or just switch it to a different channel and see if things improve.


Another possibility is something on your PC eating up encoding bandwidth. Software that uses an onscreen overlay tends to use the encoding chip on your GPU (Typical ones include FPS counters, Steam overlay, system monitoring tools, overclock programs, RGB control software, night-mode colour-modifying software, etc). Recording or streaming software is another culprit (stuff like Nvidia Shadowplay, Overwolf, Discord, or anything that records in the background to allow you to capture clips of your gameplay).


Your GPU can only have two or three encoding sessions active without getting bogged down. I have problems with notification pop-ups when I'm playing through Link--if I get an achievement in Medal of Honor, my screen goes all wavy and stuttery as soon as the notification pops up, and goes back to normal when the pop-up disappears.


Look at what's running in the background, and try shutting down any apps that have the ability to overlay messages on your screen, or anything that sounds like the list I gave above.

If your PC isn't Ethernet wired to your router don't expect great results with either Air Link or Virtual Desktop.  Also, you need to be using dedicated 5Ghz wifi without any band steering.  Also worth trying different wifi router channels.  I've found channel 36 works best for me.  I have a wifi5 1gig router ethernet wired (5e cable) to my PC with wifi 2-3m away from my play area and I've directed everyone else to dedicated 2.4. 


For me, Air Link works great with my Q2.  Since the last few Oculus/Quest updates I don't even bother to use my official Link cable or Virtual Desktop anymore.
