I have finally made the transition from a PC to a Mac by purchasing the 13-inch Macbook Pro with Retina Display. I know that the new Macbooks have the new 802.11ac Wi-Fi technology that allows for faster internet speeds. I was wondering what routers and what set-ups I need in order to take advantage of that. I currently have Comcast Xfinity and I just use the standard router that comes with it ($7 per month rental fee) and I thought it would be better to just buy my own router and set up for the new 802.11ac Wi-Fi while I'm at it. Any help would be appreciated. Thank you!
