You will need backports for that card in 12.04

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

wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.19-rc1/backports-3.19-rc1-1.tar.gz

tar -zxvf backports-3.19-rc1-1.tar.gz

cd backports-3.19-rc1-1

make defconfig-iwlwifi

make

sudo make install

And you will need firmware

wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-7260-ucode-23.15.10.0.tgz

tar zxvf iwlwifi-7260-ucode-23.15.10.0.tgz

sudo cp iwlwifi-*.ucode /lib/firmware

Reboot

If you realize that your wifi doesn't work in the future, it is likely that a kernel update occured and you will need to

cd backports-3.19-rc1-1

make clean

make defconfig-iwlwifi

make

sudo make install

Reboot for wifi
