Ubuntu: Sony Vaio PCG-71315L “Wireless is disabled by hardware switch” Help!


I'm a new user to Ubuntu and Linux as a whole, I've had it for a few months and just as I'm starting to get a feel for things my wireless decided to quit on me. This puzzled me so i checked all the switches on the Vaio; my wireless switch was on (my bluetooth was also working), and in my windows partition the problem is non-existent. Help please? Anyways after executing the "rfkill list" command this was the outcome:

1: sony-wifi: Wireless LAN      Soft blocked: yes      Hard blocked: no  2: sony-bluetooth: Bluetooth      Soft blocked: no      Hard blocked: no  3: phy0: Wireless LAN      Soft blocked: yes      Hard blocked: yes  4: hci0: Bluetooth      Soft blocked: no      Hard blocked: no  

As stated in the title my laptop is a Sony Vaio PCG-71315L

EDIT- Shortly after a few more failed attempts i was looking around and found this forum question with roughly the same problem, anyways they resolved it by switching the wifi off via the actual switch, then entering "rfkill block wifi" into the terminal, i then turned the wifi switch to on and entered "rfkill unblock wifi" into the terminal. It almost fixed it, it now picks up wifi but when my wifi's name and passphrase are entered (and have been entered correctly, many many times) it refuses to connect, thanks for the help thus far, any ideas pertaining this problem?


As I see in your rfkill list your wifi is blocked by hardware, try to unlock it by pressing combination to turn your wifi on, on most laptops fn+Fx key, make sure fn key is in legasy mode. You can do it in Bios.


If Windows is installed along Ubuntu, try login into Windows and switch in that OS. In an occasion I switch off wifi in Windows and it locked the hardware switch in Ubuntu.


The steps that work for me most of the time:

  1. Turn off power.
  2. Remove battery.
  3. Unplug from wall.
  4. Attempt to power on several times with all power sources disconnected.
  5. Reconnect as normal. Boot.
