Help with Atheros AR5001 with Ubunutu 10.04

[zuperman1]

This may help someone. I have Atheros AR5001 and I have managed to make my wifi work with the following commands:

sudo apt-get update
sudo modprobe acer-wmi

and it worked for a wile, but after I've updated the kernel, wifi stopped working. After some good hours of research I found that the problem is how the drivers are loaded. It has to be first acer-wmi and then ath5k.
So this are the commands that worked:

sudo modprobe -rv ath5k
sudo modprobe acer-wmi
sudo modprobe -v ath5k

and I've put this in the /etc/rc.local so I don't have to put this commands every time I restart my computer.

I may have spoken a bit too soon when I said that Madwifi worked. It's certainly an improvement on what I had before, but my wifi still has an annoying habit of losing the connection, and the only way I can get it back is to reboot.

I've tried Zuperman1's solution, but on entering the command

sudo modprobe acer-wmi

I get

WARNING: All config files need .conf: /etc/modprobe.d/ndiswrapper, it will be ignored in a future release.
WARNING: All config files need .conf: /etc/modprobe.d/blacklist, it will be ignored in a future release.
FATAL: Error inserting acer_wmi (/lib/modules/2.6.32-21-generic/kernel/drivers/platform/x86/acer-wmi.ko): No such device

I have similar problem. After putting my Toshiba to sleep... I cannot connect to wifi. It just tries to connect, but doesn't. After couple of sleep/waking up, it connects.

Hi

Please install the following packages by synaptic package manager
They are linux-backports-modules-lucid-generic and linux-backports-modules-wireless-lucid-generic. to solve the random blackouts...

I can't find "linux-backports-modules-lucid-generic" on Synaptic. Should this be "linux-backports-modules-headers-lucid-generic"?

Yep

Hi,
I'm experiencing similar problems on my Mac Mini (Ubuntu Lucid), which uses an Atheros AR5001 wireless adapter. Concretely, the (hardware) wireless connection appears stable (it does not disconnect), but in irregular intervals (every couple minutes) it takes ages to establish new (HTTP / TCP) connections. The browser hangs while "looking up example.com", dig yields no results for DNS lookups. At the same time I can sometimes ping my router without packet loss, sometimes with a packet loss, but always in 1-2ms.

I installed these packages to no avail. What exactly is the problem that is solved by these? Is there hope that the issue will be solved in the near future?

Many thanks for any hints / pointers!

Madwifi driver works for me in lucid and maverick. I followed that french tutorial:

http://doc.ubuntu-fr.org/atheros_ar5007eg

What I did:

svn checkout http://svn.madwifi-project.org/madwi...s/madwifi-dfs/

cd madwifi-dfs
make 
sudo make install
sudo modprobe ath_pci

echo "blacklist ath5k" | sudo tee -a /etc/modprobe.d/blacklist.conf
echo "ath_pci" | sudo tee -a /etc/modules

Restart the computer

Thanks, after trying Madwifi without success, trying new kernel that will freeze my laptop, this is the most useful post I read.
For the moment, this works, and if the problem appears again, I will let a note on this forum.
I dont know how you find this, but if this is one of the reason why this card does not work good, the answer is so easy that I am surprised nobody saw it before.
Fingers crossed,
Thanks

... and 1 day after, include reboot, this still works ... not as fast as Ethernet but really good ... I've lost so many weeks looking for the right answer.
