Just installed Ubuntu 13.10, I tried to connect wireless but It didn't detect any network. This is what happens when I check my wireless:

:~$ rfkill list
0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
1: asus-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no

I've tried with the command:

-rfkill unblock 0

but I guess it's only for soft blocks, because it doeswn't work after rebooting.

Information about network card and kernel:

:~$ sudo lshw -c network
[sudo] password for :

This same problem happened with the latest versions of Linux Mint 15 and 16.

As you stated, it's obviously the hardware switch causing this issue.

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

So my advice would be:

  • Try pressing Fn + ((i))

    where Fn is the hardware switch key on laptop keyboards
    and ((i)) one of the [F1]-[F12] keys for the wireless device.

  • Try disabling your wireless card in your BIOS, reboot your machine and re-enable the device again.

  • Finally check if the hard block is gone.
