Atheros Wireless "device not managed" on 12.04

[Carlos García]

Using Ubuntu Oneiric 11.10, with kernel 3.0.0-14, wireless card + bluetooth 3.0 "Atheros Communications Inc. AR9485 Wireless Network Adapter" works perfectly out of the box. However, on a fresh install of Ubuntu 12.04 precise alpha 2, with kernel 3.2.0-15, wireless won't work. On System Settings>Network>Wireless, it says "device not managed". However, wireless icon appears, and I am able to turn on/off wireless from the Unity panel.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't start working on it yet, because your bug report didn't include enough information.

Please include the information requested at https://wiki.ubuntu.com/DebuggingNetworkManager. If you have trouble, do not hesitate to ask for more assistance. Thanks in advance.

[Anthony Wong (anthonywong)]

Carlos, please run "apport-collect 929969" so that we can have the logs of your system.

Please also run 'ndiswrapper -l' to see if you have ndiswrapper installed.

[Carlos García (carlos-gs12)]

Fabio,
I do not know exactly what I have to do to get the info you need.
Giving me commands like Anthony would be easier.

Anthony,
I tried to experiment something, and this happened:
I made an alternate install of 12.04 alpha2, and made a wlan0 succesful connection from the text-setup.
Maybe configuration for my home network stayed after setup, because I can connect to and only my home wifi.
However, Network applet and Network Manager still display "device not managed".

'ndiswrapper -l' command showed me it was not installed.
I installed 'ndiswrapper-common' as suggested by system.
After installation, the results were:
'Error: unable to find a version of ndiswrapper!'

I ran "apport-collect 929969" as told, and authorized connection to LP, but I do not know if it did anything. Can you tell me if there is anything more I should do?

[Fabio Marconi (fabiomarconi)]

Hello Carlos
Simply open a terminal and type
apport-collect 929969
Thanks
fabio

Fabio,
I ran the command again as you told me, looks like it made it now.
Thanks!

Is there anything else you need me to do?

[Anthony Wong (anthonywong)]

Carlos, from the /etc/network/interfaces you attached, there is a wlan0 interface, which is the cause of the issue.
Have you done any wireless configuration after your fresh 12.04 install?

[Carlos García (carlos-gs12)]

Only the one made at the alternate text setup while installing.

Bug has been present though since the first boot.

[Alumni (les-sion)]

I have exactly the same issue. I installed using the alternate cd image. During the setup I only configured the ssid and password of my network and it seemed it was working. In the network indicator the status appears to be 'device not managed'. I see that ath_pci is blacklisted, but if I try modprobe the module is not found.

[Alumni (les-sion)]

The drivers are ok, I managed to connect using the terminal.

[Mathieu Trudel-Lapierre (cyphermox)]

Just delete the entries for wlan0 from /etc/network/interfaces and things should work properly. We'll still need to look again at the alternate installer to double-check why it doesn't remove these though.

[Carlos García (carlos-gs12)]

Thanks, it works!
However, that should only be a workaround and not the bug-fix,
since fresh install without configuration from the alternate-installer
will still get the bug present.

[Mathieu Trudel-Lapierre (cyphermox)]

Closing the debian--installer task as Invalid; the problem really is with NetworkManager's ifblacklist_migrate.sh script which should comment out these values.
