Bug Description

== Precise SRU Justification ==
It has been requested we provide a v3.4 based compat-wireless stack for Precise via the linux-backports-modules-3.2 package. We already provide a v3.3 based compat wireless stack for Precise so I see no reason why we should not also provide the v3.4 stack.

==Fix ==
The following branch contains a patch to add the initial compat-wireless v3.4 package:

  git://kernel.ubuntu.com/ogasawara/ubuntu-precise-lbm.git lp1023566

This is based on the latest v3.4.4 stable kernel. This was manually created following the steps documented at:


Manual creation was done because the compat-wireless archive did not appear to have a final v3.4 based tarball, the latest available was a v3.4-rc3:


Additionally, a specific request for the alx driver was made which required the -p flag (ie apply the patches on the linux-next-pending directory) when generating the tarball. Also,In order to help make potential maintenance as well as upgrades easier, I've only used a 2 digit version scheme, ie 3.4, in the packaging.

I've also provided a branch to update the meta package:

  git://kernel.ubuntu.com/ogasawara/ubuntu-precise-meta.git lp1023566

== Impact ==
LBM is an elective install so there shouldn't be any potential for regression. For those who do choose to install, it will provide an updated compat wireless stack and thus new drivers for supporting newer hardware. One example is the alx driver.

I tried your patches in #1 but i can't install it:

Anyway i tried the alx driver from http://www.linuxfoundation.org/collaborate/workgroups/networking/alx on the upstream 3.5 kernel and it worked...

--> How can i properly install linux-backports-modules-cw-3.4 ?
--> When i apt-cache search linux-backports-modules-cw i only get linux-backports-modules-cw-3.3xxx
Can you help please ?

I have a new Asus K53S laptop which cannot connect and download neccessary software.
I'm stumped with:
Wireless: AR9485 rev1
Ethernet AR8161 rev8
After installing say Ubuntu 12.04, I have no way to connect.

I guess I'll have to wait for the next Ubuntu release, or is there another way?

hi Leann,

thanks for your test packages. can you please upgrade them to a current kernel revision available on the ISOs?.
or can you point me do the old ISO-image you used?

This is currently making it's way through the Precise SRU process. At the moment, you can get the fix provided here via the linux-backports-modules-3.2.0-29.14 package (https://launchpad.net/ubuntu/+source/linux-backports-modules-3.2.0/3.2.0-29.14) in the precise-proposed pocket. You'll also need to install the correct corresponding kernel, ie linux-3.2.0-29.46 from precise-proposed as well. For instructions on enabling the precise-proposed pocket, please refer to:


After enabling precise-proposed, you should be able to install the 3.4 based compat wireless stack via lbm:

sudo apt-get update && sudo apt-get install linux-image-3.2.0-29-generic linux-backports-modules-cw-3.4-3.2.0-29-generic

or if you prefer the generic-pae flavor:

sudo apt-get update && sudo apt-get install linux-image-3.2.0-29-generic-pae linux-backports-modules-cw-3.4-3.2.0-29-generic-pae

You then will probably want to disable precise-proposed unless you wish to continue testing packages which land there. Thanks.

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.
