I have a atheros based wifi card that I would like to use with unRAID but I see that unRAID doesnt support wlan cards out of the box.  I decided to try to implement the functionality on my own and found a madwifi package for the verison of slackware that unRAID runs here: http://www.slackware.com/~alien/slackbuilds/madwifi/pkg/12.2/ .  The problem is that when I try to modprobe the module "ath_pci" i get an error that says "Invalid module format".  I've tried compiling from the source but I'm still having the same issue.  What must I do to get this working?  What am I doing wrong?

The module must be compiled for the same version of linux that unRAID is running.

 

you can type

cat /proc/version

to see the version on your server.

 

On my server, running 4.5-beta3, the version is

2.6.28.4-unRAID

 

The package you linked to was apparently compiled for 2.6.27.7.  The version must match exactly for the module to load. (including the-unRAID suffix of the version)

 

Another possibility is to install your module in /lib/modules/2.6.28.4-unRAID and then run

depmod -a

 

Then, you can use

modprobe -f ath_pci

to try to force the module to load

I'm running unRAID version 4.4.2 so the kernel version is correct.  However when I reun dmesg i get this line:

 

ath_pci: version magic '2.6.27.7-smp SMP mod_unload 686 ' should be '2.6.27.7-unRAID SMP mod_unload CORE2 '

 

How would I go about compiling madwifi myself so it is what it should be?

As I already said, the difference is the version strings... normally, they must match exactly, otherwise, the module will not load.

 

Did you try using the

-f

option to modprobe to try to get it to use the module with the mis-matched version string?

 

If that does not work, you will need to compile your own module using a version label matching that used by unRAID.

 

Joe L.

The -f option does not work. I'm just not sure how I would compile it with a version label that maches unRAID, whenever I try to compile it uses 2.6.27.7-smp.

 

EDIT:  Following this guide I'm able to compile with the correct version string: http://lime-technology.com/forum/index.php?topic=2937.0 .  I'm now getting a whole bunch of "Unknown symbol" errors whenever I try to modprobe ach_pci or anything related to it.
