Question

Random disconnecting after Meta Quest 3 v76 update (April 2025)

Hello everyone,

I would like to ask if anyone has been encountering issues after the last April update, around 24th April to be exact. I mainly use the headset with wired link to play VR sim racing. Before this update, I had absolutely no issue, shortly after the install, the VR connection is lost after about 15-30, after an intense session.

Is there any fix for this? I saw that there is no way to roll back the driver... which is quite a shame. I was so excited after I bought it and set it up, only to have it crash now every half an hour.

      I have this problem too. I fly DCS World mainly. It has appeared in the latest updates. Also handtracking is lost in my headset alltogether. I will factory reset and try, but it seems to be V76 / V77 that is the issue. Never had this issue since I bought the headset at launch.

      YEP. I did a factory reset of the headset and the problem got EVEN worse. Now I get crashes when not even using an external VR game. It crashed right when I connected Pc via link cable. I saw the diamond pattern when looking to the sides too.

      Don't bother Harry....i tested again and after about 12 minutes of flying the entire system froze.
      So ...315 + v76.0 in the headset doesn't work either

          I found something in another topic, this might be a possible workaround.

          Temporary solution for Quest Link wired V76 issues... - Meta Community Forums - 1317415

          I used an adapter to convert the original quest cable to a type A port. On the USB test C type is showing 3.1 with the adapter its 2.9, both is USB 3. I played 30 minutes, and I haven't experienced the issue. 

          One thing to mention, its charging the headset slower, so it's not ideal. Also only tested for 30 minutes, but feels like that's a progress from the maximum 20 minutes. I won't be able to test tomorrow, but thought someone might want to give a try.

            You know what a smart dev in companies do when they do a mistake to roll back to previous version, also even if u the copy pasta search milions of forum the app wont work anyway, i also notice on the oculus tools doesnt work any tool appearing error, i did milions test even formatting all nothing happen even switching pc same, the vers v74 never had problems, if they dont fix in couple month i do refound because they not providing assistance and ignoring everyone

            Those who just want to play PCVR (offline) games can avoid any USB disconnection by blocking Meta Quest Link app's internet connection with a firewall rule. (outbound)
            By doing so you never get disconnected.  In fact, inside AppData\Roaming\OculusClient are log (error) files saying that the disconnection happens from the server.

            Obviously is just a temporary measure until this issue gets fixed. But at least it's still possible to play PCVR on  latest update without the USB disconnecting. (tested it for more than 2 hours without USB disconnections).

            No harm trying. Does the cable at least complete correctly the test?


            All I can say is that recently I did (as we all) the latest update and after that I experimented for the first time those disconnections every 20-30 minutes. But that may have been a concurrence of events in my case.  (By "disconnection" I mean that the desktop link was suddenly closing with no alert of any sort and the quest 3 instantly returning to the lobby. Thinking of it now it's very likely an USB problem.)
            So I had this new undesired behavior, plus a general difficulty to open the link (cabled) connection. (infinite loading, Meta's logo screen) which also could be very well related to the USB malfunction and / or difficulty to connect to the internet or both.

            Today, by casually plugging an USB hub with a led in that port, I found that the led light of the hub was unusually dim.  I can't say if it's something that I simply never noticed or the port is dying. Also the hub isn't working when plugged in that port. The port is not "dead". It's as if it's under powered. So I swapped the keyboard and link cable... I plugged the keyboard in that under powered port and it works.

            And the link cable is now plugged in port that provides the right amount of power. Also: Lately the quest 3 was actually giving me alerts about it charging abnormally slow. (which I ignored because I thought it was related to the cable since it has always been slow at charging).  

            All I can say now is that it is very likely that the Meta Quest Link app wasn't related to my disconnections. Still, by disabling internet I surely find the connection to the desktop (via link cable) more reactive and it "never fails" in this offline mode. Whereas when I'm online sometimes it gets stuck at the loading screen. But, as I said, It could be related to that faulty USB port and / or  my internet connection behaving poorly.

            I just received an updated in the PTC channel. The version number did not change and is still 77.0.0.574.329. The postive news is that i could play voor 25 minutes without a crash.

            Have not rebooted yet...
