Comment 11 for bug 1476900

Rahul: In order for your wifi to work you either need to be running running kernel version 4.1 or later or else be using a iwlwifi backport driver from that kernel version or later. The standard kernels for 14.04 and 15.04 do not support this hardware (at least not with any publicly released version of the firmware), but the kernel in wily does.
