After V76 release, Quest pro's download speed is capped to 200Mbps

[Bobby_Vtb]

So after V76 update it seems the download speed is capped around 200Mbps and 6Ghz connection is unstable as well

I've tested on both Wifi 6 router and Wifi 6e routers and both performed simular result

I've also done some LAN connection test from my PC to Quest Pro

On the picture is side by side comparison of Quest Pro V76 and iPhone 15 Pro max connecting to my PC via a Wifi6e router with 1Gbps LAN port under the same internet environment

Meta please fix

@Bobby_Vtb  This v76 bug also seems to throttle down h.265 (hevc) on my QPro using Air Link down to 160-170mbps compared to my Q3 which can achieve 220mbps.  Pretty crazy eh!  I wonder if others using VD are seeing the same with hecv, hecv-10bit, and av1?

[Bobby_Vtb]

It's capping all LAN connection speed so no matter what you use(eg. VD/Airlink/ALVR/Steamlink) and H264/H265/HEVC/AV1, it will all get affected

Confirming v77.1024 (build 5080163.5110.340) still has the same problem.  Best case scenario I get just under 400mbps downstream.  This is really hurting PCVR streaming quality for me, so I hope Meta is putting a high priority on fixing this.  I reported the bug in-headset again on this most recent version (as I have every version since V76 first hit PTC).

I’m experiencing the same issue, and it’s frustrating to be stuck in limbo since there’s no way to downgrade to an earlier version. The problem persists in V77, and despite clearly outlining the situation in my support ticket—including that it’s not codec-related or tied to SteamVR—I only received generic responses suggesting unrelated troubleshooting steps (like using RouteThis or reinstalling Link). Even after I reiterated the details, it was clear the support team didn’t read or understand the ticket properly. No actual escalation, no acknowledgment of the widespread nature of this bug. It’s been an incredibly disappointing experience with Meta Support.

Update:
We're at 11 replies in the case chain and no signs of slowing down! Screaming into the void on this one

Nice work

Yeah we can't expect a fix soon. Another friend trying to report it got an RMA of the whole headset kit instead. And ofcourse it did not actually fix the issue.

Our best luck might be to use inside headset bug report tool. Since that sends the report to the right place atleast.

I am also experiencing the same issue. Since receiving the v76 update, the performance of Wi-Fi on my Quest Pro has fallen dramatically. In my below screenshot is a speed test to a server on my LAN, this is *not* an internet (WAN) speed test. I've typically been able to maintain 400 Mbps H.264+ in Virtual Desktop, but now cannot go higher than 150 Mbps without stuttering. My headset is connected to a Wi-Fi 6E AP (Archer AXE75) just feet away. I've made a bug report to Meta from my headset as well.

Can confirm new PTC V77 update didn’t fix this issue at all, and I’m also facing Wifi disconnect issues while I use VD on Quest Pro, some times sound delays with glitches sounds as well.

Same issue. Noticed after the update.

Same issue, thankfully HEVC is at least *usable* but still not a good experience. Hoping Meta fixes this soover than later, super frustrating.
