No wifi on easynote TE, ubuntu 12.04

[Nidding]

Hey.
I have a packard bell easynote TE where the wifi doesn't work. I've tried a few things suggested here and other places, but none of them with succes. Any suggestions as to what to do to make it work?

[Nidding]

Woops. Forgot o say that I'm running ubuntu 12.04. Also I have been able to connect to wifi through a trendnet N150 wifi adaptor, but as there is onboard wifi, I'd much prefer to use that

Please open a terminal with CTRL+ALT+T and show the outputs of:

lspci -nnk | grep -iA2 net
lsusb
lsmod
iwconfig
rfkill list
iwlist chan
sudo iwlist scan

without the stick being plugged.

Thanks for the reply

Check, which driver supports your card (if any):

modprobe -c | grep -i "168C:*0036"

If there is no output install the backport modules:

sudo apt-get install linux-backports-modules-cw-3.6-quantal-generic linux-backports-modules-cw-3.6-$(uname -r) build-essential dkms

[Nidding]

modprobe gives no output, and there seem to be some error when I try to install the backport module

nidding@nidlap:~$ modprobe -c | grep -i "168C:*0036"
nidding@nidlap:~$ sudo apt-get install linux-backports-modules-cw-3.6-quantal-generic linux-backports-modules-cw-3.6-$(uname -r) build-essential dkms
