I'm leaning towards replacing my comcast modem and router with my own stuff, in part to save the 12 dollars a month in the equipment rental. Was thinking an AC Router, though the only devices we have that support AC is our PS4, XBone, and IPad Air 2. I know future phones will be supporting AC, but with comcast, I'm only paying for 75 down and I think it's 25 up, so just wondering if I'm better off getting a solid N router and save myself 50-100 dollars.
