Horrible signal to noise ratio

This is my set up. It's in a window that is as high as the ceiling. And that window is facing the tower. As much as I moved the router ever so slightly in that window it would either make no difference or would make the connection worse. The window is blocked so no heat can come through. And there are two fans one on the bottom and one on the top of the router. It looks pretty ugly. I tried to make it nice and neat but that only made the signal worse. I will definitely try your suggestion though. Although any other location in my apartment is going to be further away from the tower and closer to inside the apartment complex which will be closer to the hallway.
