"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."
