ath_hal, ath5k, ath_pci, once and for all, what are each of them?

[eks]

Well, I've made it working, somehow, by blacklisting ath_hal and ath_pci, leaving just ath5k. On Hardy I was using a manually installed madwifi driver, I think it might had left some residues on /etc/modprobe.d. There was a madwifi file where ath5k was being blacklisted.

So, if you are on Intrepid and still cannot use wifi with an Atheros card (I think you should be able to without manually installing any driver), you need to do two things, 1) install linux-backport-modules and 2) blacklist ath_pci and ath_hal.

To install the backport modules, just search for it on Synaptic or use apt-get, it's called linux-backports-modules-intrepid. Then on System/Administration/Hardware Drivers make sure Atheros driver is activated.

To blacklist the old modules, do this:

gksudo gedit /etc/modprobe.d/blacklist

And add:

blacklist ath_hal
blacklist ath_pci

At the bottom of the file, and reboot.

IF after this steps you still cannot make it work, you probably have something left still blacklisting ath5k, thus making it not to load. You should search all the files on /etc/modprobe.d for all lines that had:

blacklist ath5k

And add a # before the start of the line, thus making it into a comment. If you, like me, is coming from a Hardy upgrade that had madwifi driver installed you will probably be on this situation.

The easier way to do this is have a Nautilus open as root and check for each file on that directory. You can do that with "gksudo nautilus" on alt+f2, but you should be EXTREMELY CAREFULL while doing this. If an admin doesn't like me saying this, please tell me and I will edit this post.

And while you are at it, or anyone else, could please explain the differences between all ath_pci, ath_hal and ath5k modules?

I really would like to understand what each of this modules are and where do they come from (ath5k comes from the backport-modules package, but where are the others??).

well this work for Ubuntu 8.10 too to get the wireless working?

I think it works ONLY on 8.10 (Intrepid Ibex). And only with Atheros wifi cards.

Thank you so much. I have been surfing forums for a couple of months, and until now, I was never even close to having my wireless working! I am extremely thankful for this post.

Thanks!

when I check under system/hardware drivers it shows that the drivers are activated but not in use. is this normal, or how do i go about getting those drivers to be used?

Hello,

I am new to Linux. I installed Ubuntu 8.10 on Presario laptop. for a while I have managed to make the wireless Atheros card work. But now it doesn't work again. I need to know how I install the package linux-backport-modules. even after updating the software I still get the message:-

Couldn't find package linux-backport-modules.

Can anyone please tell me how to install it?/where can I get that?
thank you.

[xobo]

For some reasons after the recent automatic update of Ubunto, suddenly the wireless Athros works again. It could well be that the update supply all the needed missing packages.

Thank you,

[cupevampe]

thanks eks man, this worked for me

i got a fujitsusiemens amilo pi 2515 if it can be of help to anyone

thx again

I have installed linux-backports-modules-intrepid, but on System/Administration/Hardware Drivers Atheros was not be activated. I click to activate. And then i got in dmesg:

But i added ath_pci and ath_hal in blacklist-file and comment ath5k. ath_pci can see wifi-network, but i want to use ath5k. On second computer ath5k seems work.

Also i tried:

modprobe ath5k
FATAL: Module ath5k not found.

Who can help?

[The Judderman]

I've had a very similar problem on upgrading the kernel, and then unable to load ath5k.

Any ideas?

This is putting me off intrepid, and thinking of going back to hardy or changing to mandriva (where ath5k works out of the box).

But would love to stay with ubuntu if poss...

Help anyone?
