WiFi now disabled by radio killswitch - Linux Hard blocked: yes

Errors and Solutions #29

Error

WiFi now disabled by radio killswitch

When: enabling wireless by nm-applet

Solution

This error may be because of WIFi disabled in BIOS

In this case you will get "Linux Hard blocked: yes " when you execute this command

 rfkill list

If so then enable WIFI from BIOS and reboot

This error also may be because of conflict with additional WIFI module

exec this command 

rfkill list all

0: tpacpi_bluetooth_sw: Bluetooth
    Soft blocked: no
    Hard blocked: no
1: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
2: acer-wireless: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
3:
phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no 

If you found "acer-wireless" then this may be the conflicting module, do the following to remove this module

sudo rmmod acer-wmi

Now the wireless should work, you may also need to execute this command

rfkill unblock all 


To make this change permanent ( disable acer-wmi module forever ) do the following

1- sudo gedit /etc/modprobe.d/blacklist.conf

2- add the following line @ the end of the file 

blacklist acer-wmi

  8. Thank you so much. I have been searching everywhere trying to find a way to disable the hard lock on my wifi (HP ENVY 15t-j000 with RTL8188EE chip) Everyone online just repeats the same stuff "sudo rfkill unblock all" That never worked for me. ***HP USERS*** Finally the command that worked is "sudo rmmod hp-wmi". NOTE: Probably will work with other distros, but I was using ubuntu 13.10 gnome beta 1
