How to fix no networks showing on Ubuntu 20.04 when dual booting with Windows 10

Disabling power management for networking ( Ubuntu )

The solution that worked for me was disabling power management for the network card, because my WiFi was working for about 10 minutes after startup then would shut off, I figured it was probably a power management issue since I am dual booting.

Navigate to etc/NetworkManager/conf.d, then there should be 1 file called default-wifi-powersave-on.conf, open this file in any text editor, you will find this text:

[connection]
wifi.powersave = 3

You will want to set wifi.powersave to 2 instead of 3.

3 means enabled, 2 means disabled, 1 means keep default value. This will take effect on the next reboot.
