kali linux doesn't detect wireless networks

Question

I have an Asus zenbook ux31a

It doesn't detect any wireless networks

No wireless networks are shown.

If I start a live USB I can see them.

How do I resolve this?

Solution

By default Kali does not manage your wireless interfaces using the network-manager, leaving your wireless interface for what Kali does best: pen testing.

If you want to manage your wireless interface, you can resort to iwconfig or add your wireless interface to the Network-Manager. To do the latter, open the following file in an editor: /etc/NetworkManager/NetworkManager.conf. Under the section [ifupdown] enter managed=true and reboot your computer. After this, you can manage your wireless device through the network manager in the GUI (computer/networking icon at the right top of your screen).

Also see this article, which describes the behaviour in more detail.
