“Enable Wireless” option is disabled in network settings

Question

I'm using Ubuntu 15.10 but I'm unable to access Internet wireless.

The output for rfkill list all is given below:

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: brcmwl-0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
2: hp-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
3: hp-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: yes

The output for sudo lshw -C network is:

From Hard blocked: yes it seems that your card is switched off from hardware. Turn it on and try again :) — dadexix86, Nov 25 '15 at 19:45
Look for a hardware switch and switch it... It might be that it is a "fake" switch, so maybe you have options for that in the BIOS or, if you have a dual boot, was disabled in the other system. — dadexix86, Nov 25 '15 at 20:59
no, i've not a dual boot. The button to switch off wifi...I don't use it from 5 years and is still usefull. When i press it, it open a windows in the browser (if browser is open) — Dank13, Nov 25 '15 at 21:17

Your WiFi is disabled in hardware: on Page 2-4 of the manual of your computer: press the Fn+F12 to turn the WiFi on or off. If that fails, maybe the BIOS setting is set to not use the Fn key. In that case: press F12 all on its own.

LQ queue reviewers: That's it! :-/

Sorry but it's not so simple. My F12 is already switch on, like it has ever been. Anyway is like my FN button doesn't work, I can't switch off the F12, it is always turned on – Dank13 Nov 26 '15 at 06:13
try [F12] all on its own without the [Fn] then. – Fabby Nov 26 '15 at 08:17
@Dank13: Any feed-back on the edit of my answer? – Fabby Nov 26 '15 at 18:12
no, fn+ f12 or only f12 is the same. It doesn't work – Dank13 Nov 26 '15 at 18:21
Does the built-in light go on and off when you press this button??? Do you see a difference in the output of rfkill unblock all after you press the button? – Fabby Nov 26 '15 at 20:35
the light is always light on, – Dank13 Nov 26 '15 at 22:49
Have you tried this before posting the question? – Fabby Nov 27 '15 at 17:25

Try with this command to enable your wifi

sudo ifconfig wlan0 up

to disable your wifi,

sudo ifconfig wlan0 down

If you want to disable or enable your ethernet, change wlan0 with eth0.

When I try "sudo ifconfig wlan0 up" I have this
wlan0: ERRORE leggendo i flag dell'interfaccia: Nessun device corrisponde

(sorry but I'm an italian user)

@Dank13 how about reinstall your wifi driver? yours, should be this one sudo apt-get install bcmwl-kernel-source – adadion Nov 27 '15 at 04:22
Yes, I already install it. If retry, it say it's already the installed. Yesterday I passed 3 hours on the italian forum but no one could help me. If you want I can pass here the link to ubuntu forum – Dank13 Nov 27 '15 at 19:49
