I have x200 with Ultimate N WiFi Link 5300 and linux 3.15.x. As Paul mention,
iwlwifi was split. And now they are 2 parts. On my machine these are iwlwifi
and iwldvm. Usually this driver have to be build as module, because it uses
Intel firmware blob (iwlwifi-5150-2.ucode, I believe), which could be found
here[1] and is provided as package by your distribution, probably linux-firmware. 
At the bottom [2] I have posted mine configuration about Intel WiFi card.

Regards,
Ivan
