atheros wifi not working with kernel 2.6.31-1

[Dale Trombley]

Acer laptop with atheros wifi: 03:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)

With kernel 2.6.30-10 this wifi worked so well the led light on the front of the laptop worked for the first time in 2 years. Now with kernel 2.6.31-1 the drivers fail to load at all.

Ubuntu Karmic alpha 2
Kernel 2.6.31-1 from the repositories

[AmadeuS (sarelgrin)]

Same Problem here with Atheros AR928X.

03:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)

Worked fine up to 2.6.30-9. Stopped working after upgrade to 2.6.31-1

[lpassa46 (lpassa)]

same problem on my Acer Aspire 7520G

05:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01).

Ubuntu Karmic alpha 2 amd64 "daily updated".

Still working well if booted with previous kernel 2.6.30-9.10

[itchy8me (itchy8me)]

confirmed on acer aspire 7520.

found workaround:
sudo modprobe -r -f ath9k
sudo modprobe -r -f ath5k

and then cycle a couple of times between loading and unloading ath5k, after a while the LED starts flashing really fast and tada...

[lpassa46 (lpassa)]

Good news for my 7520G.

Simply push the wireless key on the keyboard, wait few seconds and ... ops! everything is ok!

the network icon on the panel change to "connected".

Of course pushing again the wireless key turn the wifi off.

Maybe with kernel 2.6.31-1 the wireless is by default turned off ?.

[AmadeuS (sarelgrin)]

Confirmed, pressing the wireless disable/enable button springs it back to working state.

For some reason the systems boots with the device disabled...

[Dale Trombley (buzzmandt)]

doesn't work on acer aspire 3680.

I have a slide switch on the front of the pc for wifi. slide it off then slide it on, locks computer down completely. no mouse even. Have to force off then restart comp.
Also tried already having it turned off then turning it on after booting completes. still locks system down.

I think above post is right that wireles is turned off by default. Maybe if this were fixed I and wifi engaged at the proper time it wouldn't cause such a lock up on my system, not sure.

Confirmed bug on Toshiba A135-S2386 using "02:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)" and 2.6.31-2-generic

There are two method of enabling/disabling the wireless on this laptop:
   1. softkey Fn+F8
   2. toggle switch on the front of the laptop (with LED indicator)

After booting:
Method 1 does nothing. Method 2 does nothing. The following modprobe method listed by itchy8me enables the wireless:

sudo modprobe -r -f ath5k
sudo modprobe ath5k

After this, method 1 does nothing (does not enable/disable wireless). Method 2 operates as it should, it disables the wireless (cannot ping google.com). However, the icon in the upper panel does not indicate the wireless is disabled. I added a shell script with the commands listed above to get wireless working

[Andy Whitcroft (apw)]

Can you try the linux-backports-modules-2.6.31 and report back here. This contains some driver updates.

[brianafischer (brianafischer)]

I just installed linux-backports-modules-karmic and saw no difference in behavior. Please let me know what additional information would help.

$ sudo apt-get install linux-backports-modules-karmic

[Dale Trombley (buzzmandt)]

sudo modprobe -r -f ath5k
sudo modprobe ath5k

does do something, but doesn't enable wireless. When I first log in to the system my wireless says disabled, after running these two commands it says "device has no manager"

any ideas?

will try backports next

[Leann Ogasawara (leannogasawara)]

Hi buzzmandt,

After you try linux-backports-modules-karmic, and assuming the issue remains, could you run the following command. It will automatically gather and attach relevant debug info. Thanks.

apport-collect -p linux 395565

[Dale Trombley (buzzmandt)]

thanks leann....

couple of unfortunatelys

1, installing backports knocked out my wifi even for the the kernel i was connecting with (2.6.30-10), the only difference is my network manager is able to see available connections AND connect to them, but there is no communication between the wifi and browser (default firefox). firefox doesn't report offline but no connections happen, tried several different sites.
under kernel 2.6.31-2 there is no connection at all. when I do
sudo modprobe -r -f ath5k
sudo modprobe ath5k
it no longer says device unmanaged, it says device is disabled. switching the wifi hardware switch makes no changes.

2. I am a truck driver (and most of us truck drivers have laptops and wifi only connections, linux needs this to just work to have a shot at truck drivers). My only available connections are wifi.
The command you asked me to run must have a working connection to use. I'm assuming it would do you no good to run this command under a working wifi connection (correct me if I'm wrong here) Is there any commands that I can run while under the not working wifi that could help trouble shoot this and then I post the results here as a saved results text file?

As of writing this I am on jaunty livecd. I am now going to reinstall karmic alpha2 and NOT install backports to have my working connection available under karmic.

[Dale Trombley (buzzmandt)]

update, after reboot out of jaunty live cd, kernel 30-10 has wifi again, 31-2 still doesn't. holding off on reinstall

[Leann Ogasawara (leannogasawara)]

Thanks for the testing and the updates buzzmandt. If and when you're able to, like you mentioned, it'll be best to gather logs from when you're experiencing issues. The two most helpful logs will be the dmesg output as well as lspci. After you experience this issue, if you could capture the following that would be great (run the following commands from a Terminal window, Applications->Accessories->Terminal):

dmesg > dmesg.log
sudo lspci -vnvn > lspci-vnvn.log

Then when you are able to get to a stable network connection, attach those two logs files to this report. One last set of testing that we'd greatly appreciate is if you could also test the latest upstream compat-wireless stack, see http://wireless.kernel.org/en/users/Download . Assuming this issue exists in the upstream source we'll want to escalate this upstream as well and make sure the upstream developers are notified. Thanks.

[Dale Trombley (buzzmandt)]

I ran those two commands while running the kernel that wifi isn't working 31.2

am checking out the link you gave me, hope it's not over my head.

[Dale Trombley (buzzmandt)]

the dmesg_working.log above is from the kernel the wifi works in, sorry for the confusion.

this one is for the kernel it's not working in.

[Dale Trombley (buzzmandt)]

and the other one.

[Dale Trombley (buzzmandt)]

just to make the confusion complete, this one is the vnvn.log for the kernel that is working.

[Rodrigo Castrillon (rodrigoocastrillon)]

I was having the same wifi issue, but after installing the package linux-backports-modules-2.6.31-2.deb AND removing then re-enabling the ath5k module ("modprobe -f -r ath5k" then "modprobe ath5k") my wifi worked lika a charm on kernel 2.6.31-2.
My atheros device is a AR5001 under a Acer Aspire 5315-2940.

Best regards

[Rodrigo Castrillon (rodrigoocastrillon)]

Sorry, I forgot to mention that after a reboot, the module workaround must be done again.
I create a simple script and added to "startup applications":

Command to launch the script:
gksudo /home/...yourusername.../.wifiworkaround
(obviously you can change the script name :)

Script:
#!/bin/bash
modprobe -r -f ath5k
modprobe ath5k

[Dale Trombley (buzzmandt)]

thank you rodrigo, my problem is that
modprobe -r -f ath5k
modprobe ath5k
don't do anything for me. Still no wireless.

working on installing the latest from wireless.kernel.org but ran into a little snag, have posted on the ubuntu dev forums for help

make works in kernel 30-10 but not in 31-1 or -2 and have made sure headers and build-essential are installed. hopefully someone over there can help

[Dale Trombley (buzzmandt)]

OK, Lot's of help from wayne_cat and one of the peeps from wireless.org. At the suggestion of their install page I also removed linux-backports before "sudo make install". Was able to build and install compat-wireless-2009-07-12.tar.bz2 then rebooted the computer but still no wireless.

Ran sudo modprobe -r -f ath5k and sudo modprobe ath5k several times. Could not get wireless to activate. Network manager continues to say wireless disabled. still running 2.6.30-10 and wireless is still working flawlessly. Other than the kernel everything is the same, I'm just changing kernels from the grub menu so I'm assuming network manager uses the same settings and should "just work".

I tried to follow the bugs page on wireless.org and installed iw for extra troubleshooting logs but I'm afraid it's over my head.

Any suggestions are very welcomed

Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)

My wireless link died as well after an upgrade. I found this bug, read through it, flipped a wi-fi switch on the laptop, and got connected. So, in my case it was just a default-off thing.

[Andy Whitcroft (apw)]

There are a number of reports that the rfkill state is defaulting to 'off'. Could those of you suffering here collect the contents of /sys/class/rfkill/*/state and attach it here. Also could you try toggling your rfkill switches and see how the content changes, also include that information in your report. Finally does toggling rfkill enable your wireless.

[Dale Trombley (buzzmandt)]

Interesting... While running the kernel that wifi works (.30-10) for me state is 1, but when I load the kernel that wifi doesn't work (31-2) state is 0
I tried to change it to 1 but permissions wouldn't let me
I also tried to sudo gedit the file, but it still wouldn't let me save it....

How do I toggle rfkill to 1?
Is there another command that has to be ran to load the new changes?

Thanks

This is what I have so far:

Right after boot:
root# tail /sys/class/rfkill/*/state:
==> /sys/class/rfkill/rfkill0/state <==

Wifi link down, NetworkManager shows the message "wireless is disabled" when right clicking over it.
#######################################
After pressig the wifi button:

1

==> /sys/class/rfkill/rfkill1/state <==
2

Wifi link still down, NetworkManager still shows the message "wireless is disabled" when right clicking over it.
So, pressing my laptop's wifi key changes the state of "rfkill*" from 0 to 1 and vice-versa, but my wifi is always down.

#######################################
With my "rfkill0" state set to 0 (by pressing wifi key, not by manually editing rfkill state), trying the module fix:
root# modprobe -r -f ath5k
root# modprobe ath5k
root# tail /sys/class/rfkill/*/state
==> /sys/class/rfkill/rfkill0/state <==
0

==> /sys/class/rfkill/rfkill2/state <==

THEN I PRESS WIFI KEY
root# tail /sys/class/rfkill/*/state
==> /sys/class/rfkill/rfkill0/state <==
1

==> /sys/class/rfkill/rfkill3/state <==
2
And still no wireless link.

#######################################
With my "rfkill0" state set to 1 (by pressing wifi key, not by manually editing rfkill state), trying the module fix:
root# modprobe -r -f ath5k
root# modprobe ath5k
WIRELESS LINK COMES UP
root# tail /sys/class/rfkill/*/state
==> /sys/class/rfkill/rfkill0/state <==
1

==> /sys/class/rfkill/rfkill4/state <==
1

######################################
 - I noticied that my "rfkill0" is alway there, but "rfkill2" changed to "rfkill3" and then to "rfkill4".
 - Pressing wifi key only changes the state of "rfkill0", not "rfkill>1".
 - root# cat /sys/class/rfkill/rfkill0/name -> acer-wireless
 - root# cat /sys/class/rfkill/rfkill4/name -> phy0
 - In order make my wifi work I mus set BOTH rfkill to 1 and then press the wifi key. rfkill0 can switched from 0 to 1 by pressing wifi key and rfkill1 can be switched from 2 to one by removing then enabling back the ath5k module, but rfkill1 changes to rfkill2.
 - I tried many many forms of editing "state"... None of them worked. I Googled a lot :(
 - If I try editing (even if chmodding 777):
     root:/sys/class/rfkill/rfkill0# write state 1
     write: write: you have write permission turned off.
     write: state is not logged in on 1

[Dale Trombley (buzzmandt)]

Confirmed, and thank you rodrigo for showing me how to do this.... I'm now posting this from .31-2 kernel with working wifi. My process is slightly different from rodrigos but the result is the same, my wifi is working and so is the wifi LED light that goes with it.

Summary: Main difference in mine is I MUST boot my computer, then sudo modprobe -r -f ath5k. If I don't, switching the wifi button locks my computer up completely. I must hold the power button in until it shuts down, then reboot.
Also, notice in my details that when I modprobe -r -f ath5k there is only 1 rfkill result. Hoping this will help with what is really going wrong on the ath5k systems

Details:

Wifi works, LED indicator also works.

IMPORTANT NOTE: The wifi connection does not work until 2 rfkill states are present. if there is only 1 rfkill present but it's set to 1 there still is no wifi. I have tried a couple different ways to do this but if I use any other route my computer locks up.

[Dale Trombley (buzzmandt)]

now running .31-3 from repos, same problem applies. Same work around fix works.

[Rodrigo Castrillon (rodrigoocastrillon)]

buzzmandt, my Acer also hang if I press the wifi key right after booting, but pressing it againg unfreezes it.

You got me again Rodrigo lol. same thing. I took a leap of faith and tried it. sure enough, as soon as i hit the button again it unlocks. Thanks

active wifi at 1 and 1 respectively

[Andy Whitcroft (apw)]

Ok those values are interpreted as below:

  0 SOFT BLOCKED
  1 UNBLOCKED
  2 HARD BLOCKED

So it seems that when the driver is loaded and the global rfkill state is enabled then everything comes up ok, when it is soft blocked the hardware block is applied in the device. Strange. Will report to upstreams who pushing this rkfill framework refactor.

Could all of you confirm your results with the 2.6.31-3.19 kernel as this is pretty much the tip of mainline for rfkill purposes. Thanks.

[Andy Whitcroft (apw)]

Can you also include the output of the command below in your reports so we can work out which device is which:

    tail /sys/class/rfkill/*/{state,name,type,persistent}

Thanks.
