So I got a bonus from work and just got a iphone 5s and new imac last week. I thought to myself why not just give Apple all my money and get a new apple airport extreme tho I am also looking at the time capsule. My thing is I have comcast and they lease me a wireless modem/router for $7 bucks a month. Which comes out to be a little under 90 bucks after taxes and have been paying this for a couple years. I want to buy a Docsis 3.0 Modem and then buy a Airport extreme. Anyone have a good suggestion for a Docsis 3.0 modem? Best Buy which is the only electronics store near me(don't count target or walmart) only has Docsis 3.0 Modem with built in wireless N which run around $100-150. Anyone in a similar situation? Is AC airport extreme over kill. My comcast speed is only 50mbps. Getting about 44-46 up, 12 download speed. I am thinking ac to future proof it a little and because all the computers in my apartment are 2013 Macs(4 airs, 1 iMac). Live in Boston in a old building. The comcast N modem/router we have isn't all that bad. Just looking for something better.
