Unable to connect to wireless network after upgrading kernel (3.5.0-46) 12.04 64bits

Good news Chili, you don't need to pack hammer and saw. I had to do some more research to find the solution, though...Here's what happened (in case is useful for someone else):

- Acording to sudo dpkg -s, the package was not installed. Tried to do it:

 sudo apt-get install linux-backports-modules-cw-3.8-`uname -r`
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package linux-backports-modules-cw-3.8-3.5.0-46-generic
E: Couldn't find any package by regex 'linux-backports-modules-cw-3.8-3.5.0-46-generic'

Hm! I checked Synaptic, and the packages were there, appearing as installed and up to date. Weird! Well, I looked for the latest version of the backports available on Synaptic (3.12) and installed them. Rebooted...still no wireless.

- So I went searching for every piece of info about backports and found this thread:
http://ubuntuforums.org/archive/inde...t-2190930.html

The steps were:

sudo apt-get install --reinstall linux-headers-generic build-essential

Downloaded the driver package from http://drvbp1.linux-foundation.org/~...tml/backports/ , extracted it to Desktop and then went back to the Terminal:

cd Desktop/backports-3.13.2-1
make defconfig-ath9k
make
sudo make install

Rebooted and finally! Wireless was back working fine. It feels as if I had to put backports and ath9k face to face and tell them "OK guys, YOU work together, get it?" (Sorry if my interpretation is not scientific at all )

Anyway, thank you so much for your guidance and help! I've learned a few things

(I'll mark this thread as "solved")

Hi,

I have a similar problem with my Centrino Wireless-N 2230 on quantal after an updated (Network unclaimed problem).

when installing the backports-modules i get the following error:

/etc/init.d/udev: 117: /etc/init.d/udev: /usr/lib/hal/hal-system-smbios: not found
invoke-rc.d: initscript udev, action "restart" failed.
dpkg: error processing udev (--configure):
 subprocess installed post-installation script returned error exit status 127
Errors were encountered while processing: udev

do you have any clue what is the problem and how to fix it?
Thanks

I suggest you obtain a temporary wired ethernet connection and open a terminal:

sudo apt-get install linux-backports-modules-cw-3.8-precise-generic 
sudo modprobe ath9k

Your wireless should be working.

Do you have the Precise version?

lsb_release -d
uname -r

I suggest you try a reboot.

Ubuntu 12.10 is Quantal, not Precise. I suggest you follow the process described above:

The steps were:
Code:

sudo apt-get install --reinstall linux-headers-generic build-essential

Downloaded the driver package from https://www.kernel.org/pub/linux/ker....13.2-1.tar.xz (Edited from original post by chili555) , extracted it to Desktop and then went back to the Terminal:

cd Desktop/backports-3.13.2-1
make defconfig-ath9k
make
sudo make install

Rebooted and finally! Wireless was back working fine. It feels as if I had to put backports and ath9k face to face and tell them "OK guys, YOU work together, get it?" (Sorry if my interpretation is not scientific at all )
