Wow…
Many thanks for your solution!
I will try that for sure.
I’ve been looking everywhere for a simple and well explained solution.
Hope it will work for me!

Well… it did not work.

No go for me, either. Can’t authenticate WPA.

This worked for me, including authenticating WPA. It’s a shame to have to install a wireless driver from source though, bug and security fixes won’t come in automatically. Is there no better way?

…before continue with nr. 10 change to madwifi dir of course, so it worked for me too. thx a lot

@Claude did you get your wireless working in the end?
@xi Thanks for the correction I have rolled updated the post.

worked for me too! Thank you a million…
Actually at first it didn’t work. The reason was that I use localized Ubuntu and “Desktop” was translated to my language (non-latin). So ‘make’ was giving me an error. I changed to home directory (which is my name in latin) created madwifi-src directory and tried again. Then the magic happened. Make worked and after restart I enabled the driver from the admin panel.
Million thanks again!

Good job ; thanks a lot
it’s ready for my Atheros AR5001X+ Wireless Network AdapterJuly 6, 2010 10:58 PM
I’m getting this on step 2
crberry@crberry-z60t:~$ sudo apt-get install subversion linux-kernel-headers build-essential libssl
Reading package lists… Done
Building dependency tree
Reading state information… Done
Note, selecting linux-libc-dev instead of linux-kernel-headers
Package libssl is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package libssl has no installation candidate

@ Charles the end part of the command was cut off.
Give libssl-dev a go:
sudo apt-get install libssl-devJuly 11, 2010 1:01 PM
got thru it, rebooted. I cannot connect to the router, it asks for the wep key a few times and then disconnects for good. Here is dmesg | grep ath .. any signs here?

@Charles. Your dmesg output shows the driver is being correctly loaded then no DHCP offers are being made.
The last message “unknown SIOCSIWAUTH flag 12” looks like a bad return code being passed to MadWifi from the router (ieee80211_wireless.c).
Try temporarily configuring your router with a different SSID and no WEP to see if your able to connect.

You are a f***ing genious! I’ve been pulling all my hair out since upgrading to 10.04 trying to get my wireless with my AR5212 working again with no success. I was beginning to despair having to reinstall everything yet again. You are a f***ing icon in the world of Linux. Thank you for sharing your knowledge.

Hi Troy. I have an Atheros 5212 on a Toshiba U-300, and just upgraded to 10.04.
Tried using the fix, but when I try to make and install the driver (i.e. step 11), I get the following error-
cd: 1: can’t cd to /lib/modules/2.6.32-25-generic/build
Makefile.inc:66: *** /lib/modules/2.6.32-25-generic/build is missing, please set KERNELPATH. Stop.Any advice?
Thanks, MaheshNovember 4, 2010 3:19 PM
Hi Mahesh,
My guess is the compile is looking for your Kernel headers and not finding them. Does the directory exist on your file system? If not you will need to download the headers for your Kernel:
$ sudo apt-get install linux-headers-$(uname -r)
Let me know how it goes for you.

Hey Troy.
Thanks so much for your help. There were a couple of minor glitches I ran into, and was trying to figure out how to sort them out, which took me a few days. It turned out that there were a few other things I needed to do-
1. In the modprobe.d folder, there was a file blacklisting ath_pci which needed to be hashed out.
2. I needed to run an update and an upgrade.
3. Importantly, as I found out from here-
https://help.ubuntu.com/community/WifiDocs/Driver/Atheros#KurianAlternative
Kernel 2.6.32.22 (and higher) have changed the default for the rfkill parameter of ath_pci from 0 to 1, which had the effect of killing the methods described above. You’ll need to make sure that it’s set back to 0 on system startup. To do that, edit (or create) the file /etc/modprobe.d/options.conf to include the lineoptions ath_pci rfkill=0
After a few evenings of frustration trying to sort this out, it’s all finally working. Thanks again for the excellent guide!

Works with Thinkpad T41 (no, not 61) and Atheros AR5212 and Ubuntu 10.10. Thank You!

Worked like charm on an antique FuSi (wifi: DWL-G650) running Ubuntu 10.04 LTS! Thanks a lot!

This blog post has saved me a number of times now. My Thinkpad’s Atheros AR5212 wireless card isn’t get creamed every time linux headers are updated. I have to reinstall the MadWifi Driver which has better support for Atheros. Now, I just must remember to not update when only on wifi!
