[SOLVED]wlan0 up - Operation not possible due to RF-kill

FunkDojo · 2013-12-04 14:06:31

Hello everyone.

I've encountered trouble trying to activate my wlan0 interface and I was wishing that someone here might be able to help me.

$ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default 
    link/loopback 
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
    link/ether
3: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether

My attempt at trying to activate wlan0 renders the following;

$sudo ip link set wlan0 up
RTNETLINK answers: Operation not possible due to RF-kill

Unblocking everything with RF-Kill does not seem to change much in particular:

$rfkill list all
0: hp-wifi: Wireless LAN
	Soft blocked: yes
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: yes
	Hard blocked: yes

$sudo rfkill unblock all

$rfkill list all
0: hp-wifi: Wireless LAN
	Soft blocked: yes
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: yes

Enabling/Disabling the wifi-button on my keyboard only changes the Hard Blocked-parameter of hp-wifi. The Soft block remains unchanged regardless of me trying to unblock all with rfkill.

The following is the output of dmesg | grep phy0

$ dmesg | grep phy0

[    7.460715] ieee80211 phy0: rt2x00_set_rt: Info - RT chipset 5390, rev 0502 detected

[    7.500363] ieee80211 phy0: Selected rate control algorithm 'minstrel_ht'

dmesg | grep hp-wifi renders nothing.

It is worth mentioning that this problem has remained persistent throughout multiple linux distributions that I've tried on my laptop. The Wifi works fine in Windows 7 but as soon as I switch to any linux distro it stops working.

I intend to put your advice to good use so any help would be very appreciated.

Check if you can unblock your phy0 again when you first disconnect the wire from the ethernet card or set you eth0 interface down if it doesnt work.

Try this as well :

$sudo rm /dev/rfkill

and reboot.

As I can see you have two wireless interaces, when i see only phy0 with rfkill, it's maybe your hp-wifi that force to disable phy0 interace. I think if you blacklist the driver it might allow phy0 to be enabled.

Please download and install lshw available in the community repo and enter in a terminal :

$ lshw -c network

This worked!
Blacklisting the hp_wmi kernel module and unblocking everything with rfkill
aswell as re-checking the state of the wifi-hardware switch seemed to do the trick!

Thank you so much!
