I have a dual booted system with Windows 10. I have been using windows for a couple of months. However, today I decided to boot into manjaro. Unfortunately, when I tried to connect to my wifi, I wasn’t able to do so as the Network Manager was indicating “wifi disabled”. However, the wifi works fine on windows.
I’ve disable fast boot on windows. I’ve also disabled MAC randomization on manjaro by adding the following lines to /etc/NetworkManager/NetworkManager.conf
[device]
wifi.scan-rand-mac-address=no
Even this didn’t helped.
Can someone please help me and tell me how to make wifi work again.
