How To Install And Use rfkill in Kali Linux

Imagine a situation when you have to book an air/train ticket , or check an important mail quickly and the only option you have is a wifi connection from either your smart phone or surroundings, and you have only some Linux variant installed on your system. And even after installing all the necessary drivers, you are unable to get the wi-fi on your laptop working? Frustrating right? If yes, then you might want to read on about this useful utility called rfkill which you can keep in handy for those wary situations.

I own a MBP and have always found it cumbersome to get the wi-fi working on my system, mainly during those geek/hacker meetups, the only times I have to use wireless Internet. I remember randomly switching wireless on and off through the hardware switch and rebooting my system multiple times in order to get it working. Well, this was the situation until I discovered rfkill – a tool for enabling and disabling wireless devices including Wireless LAN, Bluetooth, etc. Here follows a tutorial on how to use it (fire up the Terminal before proceeding):

rfkill’s list command lets you see all the available devices, if you don’t find any of your devices, make sure you have turned the hardware switch ON and have installed the drivers for each. Here is what I get on my system after enabling the hardware switch:
