Powertop Network interface 15W power usage?

My network interface: wlp4s0 (ath9k) apparently is using 15W of power constantly according to powertop. I am using a laptop and it is the card below:

Does anyone know why this might be happening? It is completely killing my battery life.

Check the module it is using for any power related parameters.
