Ubuntu – How to turn off `airplane mode`

11.10wireless

I have a problem get the WiFi to work in Ubuntu 11.10.
When I use gnome network manager it indicates that wireless is disabled by hardware switch while it is not.

In the Network Settings Panel in the wireless section, it only shows the hardware address and the switch is off and it's disabled so that I can't change the status to On.
At the bottom there is an airplane mode switch which is On, and turning it off has no effect and it immediately turns back on.
I use a Dell Vostro 1520 laptop.

get the bios update from dell and you will be able to enable wireless in network manager.

I just tried this:

shell> sudo rfkill list all

The output was something like this:

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

Then I have run this command:

shell> sudo rfkill unblock wifi

and all is fine now :) Have fun :) I hope it will help you :)

Ubuntu – Can’t turn on wifi, Hard-blocked 16.04, HP 14

I had the same problem with a Toshiba Satellite several times, and solved it doing either:

If you have a dual boot with Windows, and you disable your wifi in Windows, in my case it also blocked the wifi for Ubuntu.
Sometimes the laptop just "hangs" on the hard-blocking and the only way is to remove your laptop battery, which resets the BIOS (my laptop does not have a cmos battery).
