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.
