[Temporary solved] Asus X201E wifi Fn+F2 toogle doesn't work

[dupont2]

Hi,

I've just install Ubuntu 13.04 in dual boot beside W8 on a Asus X201E netbook.
I noticed that the wifi Fn+F2 toogle doesn't work.
The wifi is always active and I can't switch it off.
The wifi led is off even if wifi connection is on.
I looked on the net and it seem's to be an old bug with asus laptop.

Notes : I installed yesterday 3.11 kernel but it has not solved the issue.
It is fine with W8.

Any workaround ?

Perhaps there is a workaround. Please open a terminal and run and post:

rfkill list all
lsmod | grep asus
lspci -nn | grep 0280

The pipe symbol | is on the right side of my US keyboard on the same key with \.

Thanks.

Welcome to the forums dupont2 !

You might wish to use 'Code' tags instead of 'Quote' tags for posting command outputs. It preserves the formatting of the output, thus making it more readable.

Please follow the "Using Code tags" link in my signature below to see how to use it. You may then wish to edit your above post to change the tags.

PS:
As mentioned in this thread : http://ubuntuforums.org/showthread.php?t=2172434 , does your wifi get enabled if you send the laptop to sleep, then wake it up again? Just confirming, can't dare to step over Dr. Chili's approaches

Thanks Varunendra,

Wifi is always enable even after waking up.

Oh, boy! New, unknown problems! We are pioneers! I love it!

I notice this module is loaded:

lsmod | grep asus
asus_nb_wmi 16990 0
asus_wmi 24794 1 asus_nb_wmi
sparse_keymap 13890 1 asus_wmi
wmi 19256 1 asus_wmi
video 19574 2 i915,asus_wmi

modinfo for that module says:

$ modinfo asus_nb_wmi

And the C code says:

43 /*
44 * WAPF defines the behavior of the Fn+Fx wlan key
45 * The significance of values is yet to be found, but
46 * most of the time:
47 * Bit | Bluetooth | WLAN
48 * 0 | Hardware | Hardware
49 * 1 | Hardware | Software
50 * 4 | Software | Software
51 */

Wow! Just what we are looking for, hopefully. Let's see what we can do. Please open a terminal and do:

sudo -i
echo "options asus_nb_wmi wapf=0" > /etc/modprobe.d/asus.conf
exit

Since the writers of the C code are not sure the exact correct value, we will have to experiment a bit. Now do:

sudo modprobe -rf asus-wmi
sudo modprobe -rf asus-nb-wmi
sudo modprobe asus-nb-wmi

Any improvement? If not, we'll try another value for wapf.

Hi Chili555, It says :

fred@fred-X201EP:~$ sudo -i
[sudo] password for fred: 
root@fred-X201EP:~# echo "options asus_nb_wmi wapf=0" > /etcmodprobe.d/asus.conf
-bash: /etcmodprobe.d/asus.conf: Aucun fichier ou dossier de ce type
root@fred-X201EP:~#

Aucun fichier ou dossier de ce type in French which means not such file found.

You forgot the / after etc =>

echo "options asus_nb_wmi wapf=0" > /etc/modprobe.d/asus.conf

root@fred-X201EP:~# echo "options asus_nb_wmi wapf=0" > /etc/modprobe.d/asus.conf
root@fred-X201EP:~# exit
déconnexion
fred@fred-X201EP:~$ sudo modprobe -rf asus-wmi
[sudo] password for fred: 
FATAL: Module asus_wmi is in use.
fred@fred-X201EP:~$ ^C

Fatal, so I stopped here.

[varunendra]

root@fred-X201EP:~# echo "options asus_nb_wmi wapf=0" > /etcmodprobe.d/asus.conf

...in French which means not such file found.

Because there is a minor typo in the command. It is /etc/modprobe.d. Please correct to that and try again -

echo "options asus_nb_wmi wapf=0" > /etc/modprobe.d/asus.conf

EDIT:
So you already got it before I could post and take the credit

[varunendra]

You should post the updates in new posts, otherwise people can't notice there is an update, and thus may not reply (I revisited for another reason and noticed your 2nd update) -

fred@fred-X201EP:~$ sudo modprobe -rf asus-wmi
[sudo] password for fred: 
FATAL: Module asus_wmi is in use.
fred@fred-X201EP:~$ ^C

Fatal, so I stopped here.

..because asus-wmi is being used by asun-nb-wmi. Just go ahead with the second command

sudo modprobe -rfv asus-nb-wmi
sudo modprobe -v asus-nb-wmi

(I added -v just out of habit. It makes the command verbose, so you can see what is happening in the background)

It will automatically remove-reload asus-wmi as well, since it is a dependency. Go ahead and let us know if there's a progress. I'm just filling in until dr.chilli comes back.
