Solution for MediaTek WiFi 6 MT7921 Disconnects Randomly

"I'm using the Asus TUF F15 (11th Gen, i5) that has a MediaTek WiFi 6 MT7921 module. When working on my device, sometimes it disconnects for no reason, mostly when I am away for a few minutes. I've tried too many solutions to solve the issue but failed. Even thought about changing the module, but it didn't work out. So, I found these two solutions that helped me fix the issue. Hopefully, they will help others too, as I've noticed many users still asking for a solution:

If the WiFi module is not showing, you need to bring it up first. So, try these:
Hard Shutdown: When clicking on the shutdown button, press Shift and hold it for a few seconds. Then open the device or press the power button for 30 seconds. If it doesn't work,
Uninstall the driver and reinstall it.

Solution One:
Open Device Manager (Right-Click on the Start Button > Select Device Manager).
Go to Network Adapters > Right-click on MediaTek Wi-Fi 6 MT7921 > Select Properties > Select the Power Management tab.
There, disable "Allow the computer to turn off this device to save power."
If you don't see the Power Management Tab, then follow Solution Two.

Solution Two:
Open Device Manager (Right-Click on the Start Button > Select Device Manager).
Go to Network Adapters > Right-click on MediaTek Wi-Fi 6 MT7921 > Select Properties > Advanced > U-APSD Support, and on the right side, change the value to disable. Save it.

All done. Hopefully, it will work on your devices too."

Hi what's is your version of controller?

My version is 3.0.1.1314 because I have many problems with the module

You mean the driver? I have 3.0.1.1294. As recently removed the updates for many apps and driver for different reason, didn't updated any of the driver then. But it was the latest few days ago.

I am using the same computer model as moinsbd.  As per solution 2 after Select Properties > Advanced > U-APSD Support, and on the right side, change the value to disable. Save it.  I am unable to save.  It says click OK but it does not save.  I am using Windows 11.  Do you have the same issue???

@kookiejd , I just checked again after your reply. In my device, it's saved correctly. As I already have it disabled, I tried enable and then disable again. It worked.
So it's possible that somehow device manager on your device not working. Or you don't have permission. Try to update the driver. Or uninstall and then reinstall the driver (if asked to restart, just restart). It may fix the issue.
