So I returned this tp-link ax1800 and got a netgear nighthawk ax3000..same problem. Stutters and even complete freeze ups from time to time no matter how I played with the settings. 

Just for shits and giggles tonight I enabled the 5ghz radio on my stupid little Spectrum ISP Wi-Fi router and I discovered I could enable 80+80mhz channel width and AC mode. I set the Wi-Fi channel to an uncrowded one, changed the SSID from the 2g mode, and fired up Virtual Desktop. I sit at a steady 28-30ms latency now and it's butter smooth during Blade and Sorcery with Streaming Quality on Medium at 100mbps with sliced encoding. 

I'm just amazed. That's all. 

@Chigginzz yeah thanks for the update. It's not uncommon to hear, lots of people have been saying they're having more success with older AC model routers. Currently with my tplink AX50, I have decent latency on the AC mode.

Sorry to hear your other model didn't work out, I have read several people saying specific router models work great, even on 150 streaming in virtual desktop. Try looking back to find which ones people recommended. I know at least one Huawei/xiaomi have been confirmed to work perfectly in AX mode.

I can see that this video appears to have similar issues with the ax3000, however he doesn't seem to have such issues with the ax1500. He does however believe there's an issue with the wired connection when used in connection with VR usage: https://www.youtube.com/watch?v=dVYIf0gtqg0

@XZlayeD  @Carl 

This guy could definitely be onto something about the ax3000/AX50. However it should be noted, many people in this thread also complained of the same spikes on at ax1500/ax10.

So it's odd that he's saying there isn't on his models. Still, it's something hopefully someone at TPLINK will look at, eventually. This video saying something about the wired port on the router being the cause of the latency... 🤔

@Carl this is a great update!  Thanks!

I will say I never connected anything to my TWO tp-link routers I tried except for the Oculus Quest 2 via 5ghz channel and the gaming PC via ethernet cable.

This support effort is encouraging.  Too late for me, though, as I already returned my tp-link and tried another tp-link, and then I returned that tp-link and got an ASUS RT-AX3000.

Both tp-links had issues.  The ASUS works beautifully.

Edit to add: I live in a neighborhood with houses close together.  I can see at least 20 available wifi networks.  Perhaps the tp-link routers I tried are more susceptible to interference somehow?  (this might be completely incorrect - just a little more context in case it's relevant)

@bfair31 

I can quite easily get on channels that are completely  empty so that kind of interference doesn't seem to be the issue. I  now both have an ax10 and ax50 and they both have the same stuttering issue when moving my head, except it is even much much worse on the ax50 in wifi6 mode.

@bfair31 I believe it is quite acceptable disabling AX and staying with mixed/AC, disabling OFDMA and setting Channel Width to 80MHz. Almost no stuttering, could play beat saber without any hipcups. For now, these are the best settings for me. VD: Medium / Sliced Encoding / H264 / 80Hz / 75fps

I realize that this is not optimal, but at least it worked, since I can't return it anymore. I bought ahead of time, before buying an Oculus... just imagining that an AX router would be amazing with VD... reality prooved to be quite disapointing, I almost throw up trying to play Half-Life Alyx the first time

@Carl  I tried the suggested "Guest Wifi" and it didn't work, the only connect device is Oculus. AX mixed mode - 80 Mhz - OFDMA disabled.... Beat Saber stuttering as hell, almost unplayable.

Guys, this might dilute the discussion a bit, but some of you might want to try to stream to a phone or tablet using Moonlight just to see if the problem is there. Granted the bitrates involved are different (50MB is considered max quality since only a single 1080p stream is involved), the process is simple enough if you have an NVIDIA-based system (just download the Moonlight app and it streams directly off GeForce Experience) so it should be simple enough to test.

I currently do not have the TPLINK on hand to test but I might do so if I get the time.  This might isolate the issue or provide additional info for the devs (or muddy the waters as well).  Just an idea :D
