Network Adapter not detected

  • 772

I have an Asus laptop with dual boot Windows 10 / Ubuntu 20.04. Fast boot is disabled on Windows.

Wifi had been working with no problems on both operating systems. But now all of sudden, it's gone on both.

On Ubuntu, the output of lspci is

On Windows, it does not detect any networking hardware. Windows Network Properties says:

Name: Wi-Fi
Description: Intel(R) Dual Band Wireless-AC 8265
Status: Not Present
Connectivity (IPv4/IPv6): Disconnected

How can I get the wifi back to work?
