Resolved - Unstable wifi coverage with Quest 3 on some Router Brands.

[tfosseli]

• Update January 2024 - full post history below

Hi. Let me try to give a quick TLDR summery.

Since the launch of the Quest 3, numerous users have encountered difficulties with their Wi-Fi connections related to wireless PCVR. A notable bug affects certain mid-range AX and AXE routers, such as TP-Link's AXE75, leading to significant packet losses and varying negotiation rates. Consequently, connection speeds fluctuate between 480 and 1921 Mbps, occasionally reaching 2161 Mbps but rarely achieving the full 2401 Mbps speed.

In contrast, the Quest 2 maintains a stable 1200 Mbps on 5GHz dedicated networks. However, on release, the Quest 3 struggled to reach 720 Mbps, with speed fluctuations occurring every other second.

Meta was promptly notified of this issue on launch day and has been working on resolving it through build updates. Versions v.57 to v.60 have seen a dramatic reduction in negotiation rates, making wireless VR "usable" under certain conditions, particularly when in close proximity to the router and within the line of sight. Nevertheless, users still report random speed reductions to unusable levels (below 740 Mbps), even at close range.

TP-Link has been diligently working on resolving the issue since the initial launch. Unfortunately, their latest update indicates that they couldn't make a breakthrough on their end, and they believe the problem persists on the client side. They've conducted thorough tests with various chipsets, including MTK, BCM, and QCA routers, and it seems these routers are experiencing similar issues. Their focus shifted to Meta software updates, and their most recent test with the Quest3 V60 suggests that while the negotiation rate still varies, the occasional streaming lag seems to have disappeared.

A glance at this threads posts reveals that TP-Link is not the only affected brand; users with Asus and other AX and AXE routers also face similar challenges. The root cause seems to be linked to either Meta or Qualcomm. Users have noted similar issues with the Google Pixel 7, leading to speculation about problems with the XR2 Gen2/Snapdragon 8 Gen2 drivers. So in other words it's in Meta and Qualcomm's hands at the moment.

Please reply to this thread and post your information as per Metas instructions:

"December 14th Update from @MetaQuestSupport 

Hey everyone! I wanted to let you all know that I heard back from our engineering team. It looks like there might've been some changes with the recent v60 update. I recommend checking your headset to make sure that it is updated to the latest version, and then checking your Wi-Fi connection with your headset. If you're still having trouble after updating your headset, please let me know the below information and I'll pass it along to our engineering team so this can be looked into further.

 1. Router make and model.

 2. Router firmware.

 3. Full Headset version. (59.0.0.##) Go to Settings > System > Software Update"

You can also make a video grab of your issue and send it to Meta over the "report a problem" option in the headset.

For video references on the issue here is a playlist in chronological order

NOTE: If you have a working setup with a different router and not experiencing any issues please post the details on this separate thread: https://communityforums.atmeta.com/t5/Get-Help/What-Wifi-6e-routers-currently-works-bug-free-with-th...

Original post October 10th 2023

On my Quest 3 the WIFI signal is hopping from 720 - 864 - 960 

But my Quest 2 ti stable at 1200 Mbps

I am sitting 1 m from the Ruter

Is my Quest 3 broken or is this a bug?

Edit FYI: This is a firmware bug with communication between some brand of routers. Please post your info here as a reply. (Se MetaQuestSupports reply)

The team has been made aware and is currently looking into the unstable connection reports.

Meta needs to know:

1. What version is your headset running? (Full number, i.e. 57.0.0.####)
   • Quick Settings > System > Software Update
2. Which router do you currently have?
3. Tag @MetaQuestSupport 

Also.. Remember to send a bug report via Oculus apps or headset...

Here is how: https://www.youtube.com/watch?v=7i9Q_h_yeQQ

Edit 2, to be clear: 

The issue is not dependent on AirLink or VirtualDesktop. It's a clear communication issue between the Quest 3 and certain routers in Quest build vertion 57.  That effects both 5Ghz and 6Ghz. Quest 2 is unaffected.

Here is the issue we are facing demonstrated to TP-link:

If you're r not experiencing any issues please post the details on this seperate thread: https://communityforums.atmeta.com/t5/Get-Help/What-Wifi-6e-routers-currently-works-bug-free-with-th...

Edit 3 - Update:

Version 59 showed no improvement. TP-Link has received a unit and are experiencing the same negotiation rate problems. They are investigating the problem. 

@MetaQuestSupport has stated that they are working on the issue and it will be fixed in a future firmware update. https://communityforums.atmeta.com/t5/Get-Help/Unstable-wifi-covarage-with-Quest-3-on-some-Router-Br...

Edit 4 - Update...
TP-Watched  @VirtualOmnipresence 's video  and confirmed: 

Our Wireless RD found that it might be the case Quest3 are kind Quest3's wireless connection rate strategy is more aggressive in terms of speed reduction. Once it encounters wireless packet loss or interference, it will reduce the negotiation rate on a large scale, thus affecting the actual wireless performance.

In other words, it is actually unnecessarily overly sensitive... especially when interference is basically impossible at 6GHz.

We've tested the Quest3 v57(haven't got v59 yet) so far with almost all our routers from wifi6e to wifi7 with QCA/BCM chipest...

Also thanks a lot for your updates about that article, we will also notice to get the previous quest2 sample to check how it works with our router in old firmware, then upgrade it to newer one for checking.

We will also focus on this issue later quickly if there's new firmware released.

Edit 5 - November 20th 2023

Still no more contact with meta and the silence is deafening. 

Though with the new update to v.59 it is actually a lot better on AXE75 for both 5g and 6g. It's fluxing, but not below 1200 in 6g and not below 720 in 5g. Making it... "usable"... if you are relatively close to your router.

Here is my video in my test with v. 59.

We still want to take advantage of the 2401 Mbps so that we are not reliant on no interference and being 2 to 3 meters from the access point. 

Any working 6Ghz device connected to a 6 Ghz router, dedicated at close range should output a connection at 2401Mbps. If it doesn't it's simply not working correctly. 

So I'm not giving you a pass just yet Meta. 😉

Edit 6 December 8th

A lot of new posts here and in my community on still experiencing this issue making their wireless experience unbearable. The uptick has been noticeable since the release of SteamLink bringing more people over to PC wireless. 

I also go a new confirmation from MetaSupport over email:

Meta Store Support following up on your issue.

Here is my video on testing version 60

That looks like a problem with your PC not the network to me based on those graphs. Get Virtual desktop and do the same tests with the the VD overlay on 

[Nagorak]

You can try lowering the encoding resolution in VD by one notch and see if the stutters improve. It could be you're seeing encoding stutters, rather than network. Not saying you are for certain, just that it's a possibility that may be worth ruling out.

Another way to potentially check if your encoding is not keeping up is to disable video buffering and see if you are maintaining full frame rate. If you're noticeably below 90 (or whatever frame rate you have selected) that would suggest that your video card is having trouble encoding fast enough. If you try this, be sure to re-enable video buffering after you check since having it disabled will result in even more stuttering.

[Flobud]

You guys should try to avoid doing tests with VD or any 3rd party app. Use Airlink and display overlays with Oculus Debug Tool. 

[MrRobotG]

Why? Virtual desktop is superior for wireless streaming. Their overlay is easier for people to understand and their support is amazing. 

[Flobud]

Because your tests are biased. You can't really complain to Meta for anything if you're using a 3rd party app, this is just common sense. How are they supposed to gather information in order to narrow down the issue if we all use VD? They simply could tell you that the issue is on VD side and move on. 🤷🏼‍:male_sign:

[MrRobotG]

We are testing wireless performance though, not oculus link performance.  So unless you think there is an issue with VD’s reporting/overlay I don’t see any issue with using VD. 

VD clearly differentiates between issues caused from the PC side vs the network. 

the oculus link graphs seem to confuse a lot of people on here ( or they are just ignoring what’s there and wanting to blame everything on the network )

EDIT May 21th 2024: The bug returned with build v.65. Lets hope its a hiccup.  

...

Hey everyone! Build v62 has officially arrived, and I'm pleased to announce that my initial issues have been resolved. The speeds remain rock solid at 2401Mbps, even when I'm in a different room from the router. There was only one brief 5-second disconnect, which was swiftly resolved and did not reoccur during my session.

The issues concerning fluctuating speeds, packet losses, and random negotiation rates have all but disappeared.

However, I'm aware that some of you are still encountering difficulties connecting to the 6G network in general and are experiencing random disconnects. I'm unsure if these issues are related, especially as the problem doesn't seem to be consistent with router brands.

I recommend creating a separate forum thread on the matter so that those affected can voice their concerns and avoid being mixed up with the excitement in this thread.

Thank you to everyone who has engaged in civil discussions and shared their experiences and constructive feedback. And thank you to @MetaQuestSupport and @TheAntiSocializer for making sure our issues were heard by the Meta engineers. 

Edit: if your experiencing micro studders in AirLink follow this thread: https://communityforums.atmeta.com/t5/Get-Help/Quest-3-Airlink-micro-lags-and-stutter-esp-when-movin... 

When a "problems finding 6G Wi-Fi" thread is created, share it here, and I'll add a link to it. 

(I can't stay as the OP of a post concerning problems connecting to a 6G network as I am not experiencing that particular problem and can't replicate it.)

[TheAntiSocializer]

Let's goo, that's awesome to hear!! Since @tfosseli has marked their issue as resolved, I would definitely follow their advice in starting a new topic if you're experiencing anything further. The team has also let me know that we can expect to see more ongoing improvements with each release over time, so if you're having troubles now I would suggest submitting a bug report that'll go straight to our engineers for them to review.

Oh one more thing, thank you everyone who helped/commented on this thread, you've all played a big role with any updates and information that's been provided.

[ADHenchD]

Excellent news, I'd be very interested to see more of this style of content and breakdowns by you in the future. Very interesting content.
