I'm writing this from my girlfriend's laptop, because manjaros network manager stopped working.
It doesn't show my wifi AP. (wpa)
However other distros, like linux mint can see the networks.
Manjaro live usb cannot see it anymore, nor the installed system from yesterday. I did nothing around the network manager, but it's strange that the live usbs don't see the wifi. But live linux mint does.
Before this, live manjaro was able to see the wireless network.
I get this output:
@manjaro ~]$ iwconfig
enp0s7 no wireless extensions.
