We just dumped AT&T's weak service, and are upgrading to the Comcast Blast 75 mbps internet only service. We are coming from a 10 mbps (if lucky) service, and it is not great for multiple devices at once. The modem/router combo that AT&T provided was ok, but I have heard those that include both are spotty. Based on that, and the fact that it costs $10 per month to rent one from Comcast, we opted to provide our own modem and router. Honestly, I know nothing about modems and routers (other than doing internet research), and am more confused now than ever. We are in a small/medium apartment, and use almost all brand new Apple devices (Apple TV 4 & Apple TV 3, iPhone 6S & 6S Plus, 2 iPad Air 2s, a 2011 MacBook Pro, and an HP PC) and know that the new 802.11 ac is the gold standard and is something we may be interested in. We are just not sure where to begin. Any suggestions? Not sure what our budget is for this "project" yet since having reliable, powerful (75 mbps powerful not a gigabit or anything lol) internet is important to us and we know it can be pricey. Thanks!
