[SOLVED] Fedora 15 ath5k problem

tuckx · #1 25th May 2011, 07:57 PM

hi,

I have some troubles with the ath5k module.
I update my system from fedora 14 to 15.

It seem this is a kernel bug but maybe someone have the solution.

This problem does not exist in fedora 14 and 13 but on fedora 15 the driver ath5k dont work.
My wireless card was recognise but I can't detect any network.

My kernel : 2.6.38.6-27.fc15.i686
wireless card : Atheros Communications Inc. AR5001 Wireless Network Adapter

result of iwlist :
# iwlist wlan0 scanning
wlan0 No scan results

Is the card definitely up?

ifconfig wlan0 up

it's not that, no, with that bug the connection is possible but you get slow transfer rates, and it is specific to ath9k, not ath5k. this looks like something different.

I'm not on Fedora, but I use a self compiled Kernel. I noticed that since Kernel version 2.6.38 my wireless stopped working. My card is a Atheros AR2413 which uses the ath5k module.

In 2.6.37 wireless works flawless. As soon as I boot 2.6.38 or 2.6.39, device is activated, drivers are loaded, rfkill is unblocked, but iwlist scan finds no access points. Also iw dev wlan0 scan produces no output.

A common hint is to add parameter nohwcrypt=1 to ath5k, but that doesn't help here.

ok, thx for replies

crudeOIL : I read some news about serious unstable atheros driver with 2.6.38 kernel, so I think I have to wait a kernel update.

I dont want to use the madwifi driver because it dont work very well.

The ath9k driver dont work with my card and I don't need custom kernel because all the modules I need are here.

rfkill was unblocked to.

After some investigation, I don't think ath5k is causing the problems.

I have the same wireless chip in two computers: one in an acer laptop and one in a desktop pc. As I took a testdrive of 2.6.39 on the desktop, the wireless was working. So at the moment I'd blame the acer-wmi module.

@tuckx: What in what PC is your wireless built in?

i too have issues with atheros wireless card.. i'we a 2yrs old laptop, ath9k is the kernel moduel.. i've esperienced some speed relate issues,as described in the bug report here
http://fedoraproject.org/wiki/Common...9k_performance
but i can't ste up a system using temporary bugfix provided because of a different problem.. once switched off the wifi, either from software (network manager) or hardware via the notebook button, it never come up. i've tested two different installations, one from live one from dvd, distro full updated, and the problem is the same. now i'm back to f14, tath has no problem,and i expect solutions to come over.. f14 is rock solid now, and i consider stayng there, testing kde4, that is the same as is in f15, but without problems.

For ath5k, I suspect this could be the issue:

https://bugzilla.kernel.org/show_bug.cgi?id=34992

please make a separate thread for ath9k issues, these are separate modules and issues in the two are not likely to be related.

crudeOIL · #11 4th June 2011, 09:31 PM

@AdamW: The bug report covers my issue, thx.

Meanwhile I switched from ath5k to madwifi and wireless connection seems stable so far. As soon as the patch is integrated into vanilla I'll try ath5k again.

Hi there, i'm having this problem as well. ive never really done this kind of thing before.
so i need ath5k, this patch and a custom build? would anyone mind walking me through
this a bit? thanks in advance.

Hi everybody,

Good news you don't need anymore to use madwifi driver or the pach compat-wireless to have a atheros wifi card working.

How it could be possible you may ask !

Nothing is more simple just do an update to the latest kernel : 2.6.38.8-32.fc15

thx to kernel team.

sdugaro · #14 9th July 2011, 05:02 AM

Wow that's awesome! Ill try and figure out how to do that... but any help here would be appreciated! Thanks!

---------- Post added at 04:02 AM ---------- Previous post was at 03:49 AM ----------

that easy! wicked.

This update can be installed with the "yum" update program. Use
su -c 'yum update kernel' at the command line.
