Recently I came across below error after installation of Ubuntu 14.04.
“Wireless is disabled by hardware switch”
This tutorial will show you how to overcome above error by enabling/disabling Wifi/Bluetooth using RFkill command.
RFkill is a part of kernel through which radio transmitters in a computer system can be queried,activated or deactivated.
To display RFKill enabled computer devices ,use the below command:
rfkill list all
Using RFKill command , we can block/unblock devices using Index number or Category name.
Using index number :
sudo rfkill block 1
Using Category name :
sudo rfkill unblock bluetooth
Example:
Hope this tutorial helps you out !
