I am going to upgrade my entire home network within the next two weeks. The equipment on the network will be (2) Windows PC's running N, a Mac Book Pro running AC, an XBox, (2) iphones AC, (2) smart TVs, one printer and NAS. I am currently using a Netgear WPN824 that only runs B & G with the xbox, 2 iphones and 2 windows pc's. I want to get something that will give me a lot more speed and range. This will be in a 2800 sq ft house so I need something with distance too. Been having problems with dropping off. My current router is over 10 years old. I don't know much about routing so wanting something that doesn't require a engineering degree to set up. My budget is around $300 or less. Want simplicity and stability without sacrificing a lot of speed. Looked at the Nighthawk X6, Asus AC87R and the AC68U but open to any suggestions. Thank you for your help and advise.
