AR9285 on 4.4.0-66-generic

Hello, I just swapped wifi card in my Thinkpad X60 and encountered a problem with missing ath9k module.

sjal@MegamanX60:~$ lspci | grep Ath
02:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

sjal@MegamanX60:~$ sudo modprobe ath9k
modprobe: FATAL: Module ath9k not found.

ifconfig -a shows only the loopback and the ethernet

Any aid would be nice, I'll just try tinkering with a different kernel now

PS This is a 32bit processor architecture, the xrandr is also buggy for me here
