I have a new B650M Mortar board running a Ryzen 7700X. Windows 10 installed fine and ran for a few days. Then the wired network interface dropped out. After a reboot, both the wired and wireless adaptors were missing. Windows listed them under hidden devices as not being present. When booted into Bios, the bios says they are enabled. Booting back into windows saw them as still missing. Booting a Linux standalone USB system also didnt detect the wired or wireless network.

If i clear bios completely by removing the battery and then boot into Windows, both adaptors appear and work. However, a few hours later they disappear again.
So it doesnt appear that the wired and wireless devices themselves are faulty. The board, overall, stops presenting them to the operating system.
edit: bios has been updated to latest version

Hi
Try replacing the battery. It's a standard CR2032.
Otherwise you may need to RMA the board.

Can you also try a full power off unplug PSU and then press the Case power button for 10 seconds.
Power back up psu and boot to OS check to see if Wi-FI is back

If not as has been mentioned RMA the Board
