Default Touble getting ath5k wifi working on Ubuntu 11.10

Hi, I'm having trouble getting the wifi working on Acer Travelmate 2450 which supposedly uses ath5kThe driver was working fine on Ubuntu 9.10, but stopped working as soon as we upgraded the machine to 11.10



What we've tried so far is to blacklist the ath5k driver in /etc/modprobe.d/blacklist.conf and setup ndiswrapper using a windows XP driver for it. Doing this, we manage to see the wifi networks, but can't connect to any of them (using the KDE network manager).



After blacklisting the ndiswrapper, restarting again and trying to svn checkout the latest version of madwifi and doing a make && make install, there was no trace of wifi on the system whatsoever.



Have also installe wicd to see if it makes config easier, but no luck.I case you're wondering, the wifi is working, currently running my macbook via the wifi, just can't the Acer note book to connect via wifi.



For the last 4 days, we've tried about every blog article on the ah5k and ath9k we could find and still it's a problem.

Try installing linux-firmware-nonfree package, remove the blacklists,
and check if it works.

This has been the solution for probably all
the-wireless-is-not-working issues I have seen in this mailing list.

Default Touble getting ath5k wifi working on Ubuntu 11.10

Did a clean install of Ubuntu 11.10 just to be sure it's not something I've messed up.
First time it booted into Unity, it could see the wireless networks, but just wouldn't connect, rebooted, now there's no wireless connections to connect to.



Reinstalled the non-free drivers with
sudo apt-get install linux-firmware-nonfree
and still nothing to connect to.

iwconfig:

lo******* no wireless extensions.

eth0***** no wireless extensions.

I don't know about dmesg, however I think you may use 11.10 Live CD

and see if wireless works with it.



If it works, then it is some configuration issue, which will be fixed

if you do a clean install.

The command

dmesg

should reveal if there is a problem loading the firmware to the wireless
card. Or you could have a look at the file "/var/log/syslog".

You could try the command

sudo iwlist wlan0 scan

to check if you can see wireless networks. IIRC, I once had a situation
where network-manager didn't show my AP before I used that command. But
I prefer to use wicd instead of network-manager. Maybe you could try
wicd as well. If you do that, please uninstall network-manager because
otherwise both wicd and nm want to handle the wireless network and both
will fail.

Doing a "sudo iwlist wlan0 scan" just says no results found (that's after shutting it down and bringing it up again, otherwise it doesn't scan).

Some snippets of the dmesg output, error message in error log "wlan0: link is not ready":

The command



dmesg



should reveal if there is a problem loading the firmware to the wireless

card. Or you could have a look at the file "/var/log/syslog".

You could try the command



sudo iwlist wlan0 scan



to check if you can see wireless networks. IIRC, I once had a situation

where network-manager didn't show my AP before I used that command. But

I prefer to use wicd instead of network-manager. Maybe you could try

wicd as well. If you do that, please uninstall network-manager because

otherwise both wicd and nm want to handle the wireless network and both

will fail.

Default Touble getting ath5k wifi working on Ubuntu 11.10

Sorry for the late reply.

To me it looks like a bug in the ath5k module. The module registered
IRQ21 for ath5k and then doesn't handle that IRQ for some reason. I
suppose that is the reason why you can't use your wifi. I think you
should report this bug:
<https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies>.

Until this problem is resolved, you could try ndiswrapper (as you
suggested in the other mail) if you have the Windows driver for that
Atheros card. Or you could try the kernel of the upcoming 12.04 version.
Perhaps the bug is resolved there already. You can find that kernel
here:
