One thing I found is that Windows will often re-enable power saving on the card. Even on the same boot it sometimes becomes enabled again. I just check it before I start VR.

Have you tried my fix I described on the last page? I had some issues last night even with my fix applied. 2 or 3 disconnects in 3 hours of play in Flight Simulator.

Just an update. This fix I posted has almost completely solved my disconnects. I've played about 40 hours of VR since my original post. In that time I've had maybe 3-4 disconnects. FAR better than before, where I would regularly get disconnects every 20 -30 min or even worse. I recommend periodically checking the device manager, after a couple disconnects I found that the devices on the card were set to save power again! Once I disabled power saving again the disconnects are very rare. In 40 hours I've had maybe 4 disconnects, and I attribute most of them to signal loss due to the placement of my PCI-E card antenna. Hope this helps. Happy gaming!

My Specs and config: Asus Rampage V Extreme X99 motherboard i7 6950x 10 core 4.4Ghz OC 32GB 3200Mhz 14-14-28 1T RAM RTX3090 (Just got this in January, was 1080Ti since 2018-19) Windows 10 Pro x64 20H2 Build 19042.985 Monitor: 65HU9000 4k TV (2014) HDMI 2.0 Intel 750 1.2TB SSD PCI-E 4x Aquantia AQC107 10GB Ethernet Adapter PCI-E 4x Like I said, I've had the random disconnect issue for a very, very long time. The fix above has solved the issue for me for about 10 hours of playtime so far. I applied this a few days ago. In my BIOS settings I've got my PCI-E set to Gen 3. Also I have ASPM PCI-E power saving disabled, in Windows power management as well the BIOS I believe. Besides this issue this PC works flawlessly. I currently have the latest Nvidia driver installed. I have been mostly free of the Nvidia issue that causes frame drops with newer graphics cards. Hope this helps others who run into issues.

I've had this issue for a very long time. Random disconnects. I tried all the fixes listed here. The controller timeout fix didn't work for me. The setting USB devices to never power off didn't help either. At least not the normal USB devices and hubs listed in device manager. This is what seems to have finally solved this for me: Open device manager. Click view and then devices by connection. Find the PCI-E port that your card is attached to. My Intel PCI-E card is attached to Intel PCI Express Root Port #8 I set every device under this PCI-E Port to never power down to save power. This is the whole Intel Wireless VR Card, its software component listed here as well as the USB Root Hub. After disabling power saving on all of the devices that are part of the wireless PCI-E card I have not had a drop since. Screenshot below:

Same here. Been dealing with this issue since purchasing the wireless VR. Found this in a log file in the system info program: [2020-05-10 13:11:32.053 -7 0x4A84 INFO LOG] MCU Update Closed.

Seems to be something to do with the intel software.

Same here. Got the set on Black Friday. My controllers never indicate full charge. Haven't tried the replug trick yet, but they don't take long to charge anyway so I just unplug them after about an hour. Would be nice if this worked correctly like the OG controllers did.
