Tags: #Firmware Update #6 GHz #Meta Quest 3 (VR) #Bandwidth Control/QoS #GXE75
Model: Archer GXE75  
Hardware Version: V1
Firmware Version: 1.1.0 Build 20251017 rel.64550(4155)

As I'm sure many of us are aware, the GXE75 has current issues regarding the Quest 3 / Pro & the 6Ghz channel in the form of disconnections and Ping spikes depending on current firmware.

Issues with firmware version -  Archer GXE75_V1_1.0.5 Build 20241217 *AND BELOW* were fixed

Issues with firmware version -  Archer GXE75_V1_1.1.0 Build 202510107 BETA 

Both the 5Ghz & 6Ghz channels seem to be affected by the 160MHz band.

THIS LEADS TO SEVERE PING SPIKING ON BOTH CHANNELS AND CAN BE RECREATED EASILY


 

PING SPIKES CAN ALSO HAPPEN REGARDLESS UPON DEVICE SLEEP/WAKE - THIS INCLUDES DESKTOP STREAMING VIA VD/STEAM/META & DOES NOT STABILIZE - THIS HAPPENS ON BOTH 5 & 6GHZ CHANNELS

 

As another user had mentioned in the post - https://community.tp-link.com/us/home/threads/topic/845440
"Setting the 6G to 20/40/80 hz enables to quest pro to use it without issue, both headsets can't be on 6G at the same time though otherwise they have latency issues"


This seems to hold true, however; I'd connected my phone to the 6ghz channel to test if it was possibly an issue due to the device type (Multiple quests, etc) but this doesn't seem to be the case. Having another device connected to the 6ghz channel at all, regardless of usage seems to cause instability on the network. This happens regardless of TWT / MU-MIMO being enabled or disabled.
(Note that smart connect is disabled and all SSIDs are separate to avoid confusion)

 

I then tested with another smartphone to make sure (Pixel 6) and yet again, had the exact same issue. It doesn't seem to be a factor of what the device is doing, more that it's on the same channel at all. From what I've tested, manually choosing the channel (disabling PSC & choosing best channel in regards to least interference) also doesn't seem to make a difference in this case.

 

As mentioned, this is on the current Beta firmware so mileage may vary, but PLEASE sort this out. It's insanely frustrating & losing a 2.5gbps port by purchasing an AXE75 instead, just to have a stable experience, is such a headache.

I have the same router and would have the same random disconnects but it would usually only happen when I first turned on the headset and rarely when in game so I've installed the beta branch, I get >500 latency now on 6G with both 160mhz and 80mhz. I was able to get it stable with 80mhz but then I went into the meta settings to adjust my room boundary then went back into VD and had a massive 250+ latency spike constantly. I haven't been able to get it working on 6G after this. Haven't tested 5G since it's going to be a much worse experience.

Hello @sadboi ,

Sorry for the late reply.

 

You downloaded the beta firmware from here, right?

 

Based on your description, the main problems are as follows:

1. When both the 5G and 6G channel widths are set to 160MHz, connected clients experience a significant latency spike.

2. When the 6G channel widths are set to 20/40/80 MHz, it is impossible to connect two 6G client devices(including phone and  QUEST 3) simultaneously; otherwise, latency spikes also occur.

At this time, can devices on other networks, such as 2.4GHz and 5GHz, connect to the network normally?

Is the Quest 3 stable when connected to 5GHz (80MHz)? 


I noticed your case has been escalated to the system engineering department. If you have any solutions, please feel free to share them.

Hello @Niqy ,

Thanks for contacting our community.

 

May I know the firmware version of your router? Is it Archer GXE75_V1_1.1.0 Build 20251030(Beta firmware)?

Have you tested the 5GHz for QUEST 3? If it works, please tell me the channel width at 5 GHz.

Have you encountered a situation similar to Sadboi's? That is, even if the 6GHz channel width is set to 80 MHz, it is impossible to connect two 6 GHz client devices simultaneously.

Hi Joseph,
That is the correct firmware I downloaded, there seems to be additional problems with the Beta firmware that I've disclosed to the engineering team via email correspondance.

1. Either channel can be set to 160mhz and have the issue occur, it doesn't matter if it's one or both.
2. You are able to connect a second client, but you will run into the latency spikes to an extreme amount if you do so, likely do to aggressive rate throttling.

Other devices are capable of connecting to the 2.4/5Ghz but attempting to stream to VD is basically impossible. The Quest also doesn't seem to be stable on 5Ghz at 80MHZ either.

Additionally, it seems as though downgrading / restoring / updating firmware is no longer possible due to the beta revision, any attempts to do so result in an error and will not proceed.

At this point in time, I don't see there being any ways to get around this until the issues are resolved via the engineering team. I'm honestly at wits end and am attempting to see if there can be a replacement unit of similar spec arranged.

Hi, 

-My current firware version is: 1.1.0 Build 20251017 rel.64550(4155)

-Luckily I don't have much 5Ghz interference and am able to connect to the 5GHz band at 160MHz without any latency spike issues running at around 40-70ms.
-I've tested the 6GHz band on both 80MHz and 160MHz and I get the same constant 300-500ms latency on my quest 3 whereas it used to be around 30-50ms on the previous firmware version. I am able to connect to the 6GHz band with my quest 3 by itself just fine, haven't tested connecting two devices because that's not my desired use case of this router, I only want to connect my quest 3 to the 6GHz band to have optimal latency.

Thanks, let me know if you have any more questions.
