I've seen this question already asked and tried suggested solutions but none of them seem to work. I've had the wifi become disabled previously but rebooting the system usually worked. This is not working now. When I run rfkill list all, I get this:

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

How do I undo the hard block? I'm using a Dell Inspiron N7010 with an Intel Centrino N-6200 card.

Edit: Output of lspci -knn | grep Net -A2 is as follows:

Inspiron-N7010:~$ lspci -knn | grep Net -A2 03:00.0 Network controller [0280]: Intel Corporation Centrino Advanced-N 6200 [8086:422c] (rev 35) Subsystem: Intel Corporation Centrino Advanced-N 6200 2x2 AGN [8086:1301] Kernel driver in use: iwlwifi

  • Please edit your question and add output of lspci -knn | grep Net -A2 terminal command.

    Hard blocked means that you have a hardware switch or button somewhere and this is switched to the off position. Sometimes, this is a fn button and other times there is an actual switch somewhere.

  • What options are in BIOS under Advanced/Wireless?

"Hard blocked" refers to a hardware switch not a software issue.

There should be a slider switch on either side of your laptop to enable wireless.

Here is an example of a similar one.

In this photo, the wireless switch is on the left.

If you don't believe me, run the following command:

rfkill block 0

Now, check out what rfkill says:

rfkill list

and you should see now that you have a soft block in place:

0: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: no

Run the following command to remove the Soft block:

rfkill unblock 0

    There are also keyboard combinations on some laptops. You generally look on the function keys (F1, F2, etc.) for a WiFi symbol. Then you either just press that function key or you press, for example, Fn+F2 if F2 has the WiFi symbol on it.

  • @Olathe I did think of this however, most Dell laptops have an actual switch and additionally, using an fn key combo to disable wifi will usually result in Soft blocked as well.

  • @Olathe I believe the fn combo for this computer is fn + F2

    I was just adding it because I think the answers for this question should be useful for most people running Ubuntu, rather than just for a specific Dell model.

I'm having the same issue when resuming from suspend.

I wrote a script on sleep.d folder with

rfkill unblock all

this activates my wireless (all the rf devices) every time I resume my laptop.

This command may work for you too.

  • hard blocked usually refers to hardware switch instead of software.

  • @mchid I know, but worked for me. May sound weird but i'm thinking more on a software issue that makes the "Hard Block" status. Nov 27, 2015 at 4:23
  • That usually falls under Soft blocked

  • @mchid I understand what you say, but maybe a software issue can cause to appear as "hard blocked" without being physically switched off. Nov 27, 2015 at 19:35

I tried fn + f2 but that didn't work. What ultimately worked was shutting down the computer, removing the battery, holding the power button for 30 seconds, turning the computer back on and then going into the BIOS and resetting BIOS to the original settings. Not sure why it worked but after the computer powered up, wifi was active again.
