No wireless for Intel Corporation 7260 version 63

I suggest you download this to your desktop: http://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.11-rc3/backports-3.11-rc3-1.tar.bz2 Right-click it and select 'Extract Here.' Now open a terminal and do:

cd Desktop/backports-3.11-rc3-1/
make defconfig-iwlwifi
make
sudo make install

Now download the required firmware here: https://git.kernel.org/cgit/linux/kernel/git/egrumbach/linux-firmware.git/plain/iwlwifi-7260-7.ucode Now open a terminal and do:

sudo cp ~/Desktop/iwlwifi-7260-7.ucode /lib/firmware/  <--or wherever you downloaded it
sudo modprobe -r iwldvm  <--If it is not loaded, OK, please proceed
sudo modprobe -r iwlwifi <--If it is not loaded, OK, please proceed
sudo modprobe iwlwifi

Your wireless should now be working.

For those that can't get the ucode file from the above link use this link: http://www.intel.com/content/www/us/en/support/network-and-i-o/wireless-networking/000005511.html

After installing Ubuntu 14.04 Trusty on my Dell Vostro 5470 laptop, I had the same problem. Installing the newest driver worked for me, no need for backports.

It can be found here: http://wireless.kernel.org/en/users/Drivers/iwlwifi#Firmware

In the driver files, there is a Readme with instructions, but here is how to do it:

Download the driver on your Desktop: http://wireless.kernel.org/en/users/Drivers/iwlwifi?action=AttachFile&do=get&target=iwlwifi-7260-ucode-22.24.8.0.tgz

Extract the contents on your Desktop.

sudo cp ~/Desktop/iwlwifi-7260-ucode-22.15.8.0/iwlwifi-7260-8.ucode /lib/firmware/

Restart.
