I wave the old flat (not the new tower style) 2TB Time Capsule. It's still working OK, but is getting old (~5 years). Also, the coverage could be better. iPad barely gets a signal on the deck, which is not that far from the router. It seems like it used to better. Just got a new 2015 rMBP, so thinking of upgrading the networking as well. Anyone have recommendations on a new router that can also support TimeMachine on an external? I know I could get the new Airport Extreme, but wondering if some of the new Asus or Nitehawk's are now preferred?
