I'm completely new to Ubuntu , I have Ubuntu 14.04 installed. I am unable to turn on the wireless key in the network panel.

Whenever I try rfkill unblock all and rfkill list all then it shows ->

soft blocked : no
hard blocked : yes

even if I try to press Fn F12(wireless key in my laptop) the soft block changes but noting happens to the hard blocked!

I use a hp-envy ultrabook model : 1104tx . Please help me out here , I have tried every possible solution that I am aware of.

"Hard Blocked" refers to a hardware issue and "Soft Blocked" indicates the connection is blocked by software (rfkill for example). In other words, rfkill commands have no affect on a hard blocked device.

Check for a physical switch or possibly an fn key that can toggle the wireless on and off. Make sure wireless is enabled in BIOS. If you have a BIOS option for wireless and it's on, turn it off and back on again to see if that fixes the issue.

Alot of people say they have fixed this problem simply by booting into windows, turning wireless on and rebooting back into Ubuntu and they no longer have the problem. Try booting into a Live disk or another linux distro you may have on another partition to see if you can fix the problem there.

Are you sure you installed the additional wireless drivers? I have had the same problem, and if you haven't got your wireless drivers you would need to install them and then (if not already) turn on your wireless card. After that, you may need to restart your computer, if that doesn't work then try typing the command:

rfkill list all

And if it shows that 'hard blocked' is yes then type:

rfkill unblock all

If the output is soft blocked: yes and hard blocked: no then you're good to go!!

Hope this helped, Paul

  • rfkill don't ususally work for hard block, mostly only soft – mchid Aug 18 '14 at 19:46
