Re: Atheros AR3012 problem in Ubuntu 12.04LTS

Hi,

Thanks for quick response.

We are using standard Ubuntu release. We don't have access to Dell
pre-installed version (yet) as it's not available/supported in Finland.
I have asked it from Dell but let's see if we get it or not.

BT isn't working on standard 11.10 Ubuntu either, nor in 12.10.

We haven't tried manual binding yet. We'll check it.

So the driver works with the pre-installed version?

Are the sources for this pre-installed Ubuntu publically available
somewhere or is it just a stock Ubuntu release? Being able to see kernel
sources from that release would help.

I didn't quite get this 2) part. How do you know that all drivers and
firmware are available? Earlier you mentioned about some special driver.

Have you tried to manually bind the device to those drivers? With very
good luck it might work (but I doubt it).

Also did you file a bug to Ubuntu? If the driver works in 11.10 but not
in 12.04 that's a regression.
