No available connections after installation

Hello, I’m new on linux.

I just installed Manjaro KDE but I can’t find my wi-fi, it says " No available connection ". It worked just fine on windows. Can anyone help me?

( Sorry for my bad english )

Of course you have to do it for your running kernel version

Or go this way

but for that you will have to install the linux headers

sudo pacman -S $(pacman -Qsq "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-headers"}' ORS=' ')

You will be able to do this while using phone tethering, so you get internet access …
