In short: - Two story, 4000 sqft home, typical modern construction standards; - Approximately 15 wireless devices; - Some wireless PC gaming; - Moderate data use as far as 4K/HD streams; - Occasional upstream use for backups; - Residential cable connection, ~350-400 down. Modem connection, thus router connection, is currently at main computer which itself is at a corner of the house. Have tried: - Airport Time Capsule, latest generation: tried and true, now discontinued. See above for setup. Expected wireless signal drop-offs at opposing corner but has been quite passable in general. - Synology RT2600AC: preferred Airport. - Eero: liked app and design/style, but lesser performance in my use case. Iffy support in my case. - Orbi: performs well, though occasional odd hiccup in gaming despite QoS and otherwise solid hardware. Options in my mind: - Sticking with Airport as I did for years, still get to use Time Machine, though not ideal (deprecated hardware, no QoS, etc); - Newer Asus router, seems to be a common favorite, also allows Time Machine use; - Whether a newer Asus unit would offer satisfactorily better range/throughput on the other side of the house; - If I really need a mesh or mesh-like system like the ones tried above, since I like the simplicity of one device; - Unsure how I would structure an Ubiquiti setup in this house, seems some like them as well. Appreciate any thoughts/advice.
