average for home use....but stability not sure if its still the same as what many reported last time...but can be use ,just be patient with it and might need to restart if it starts acting up .

Not sure what's the stock router that you will be getting, so no comment on that, but if they are giving you D Link or other than the usual like TPlink or Asus, then you will definitely face a long run of issues and headaches once getting it.

If you have cat6 wiring infra works done with proper trunking. Then I would suggest to use the ethernet cables to backhaul all of your routers/aps/mesh.

Mesh wifi is just a marketing term for easy roaming/pairing of multiple routers/repeaters/APs.

The main purpose of the "mesh" term is that whenever you go from one spot to another spot, you do not have to change WiFi SSID or face disconnection from the SSID. It will sort off help you to roam from one spot of the house to another spot seamlessly.

For a family of 3, you got to decide which floors are you going to be using the most, and which floor requires the most of out your wifi. And also your ISP subscribed speed. Then only you can narrow down to which type mesh and its rating AX1800/AX3000/AX6400 etc.

Just stick with WiFi6, is more than enough for the next 2-3 years.

Go for Asus if you prefer timely and more frequent updates. and ASUS router have more community support in terms of custom firmware.

TP Link updates comes less frequent and usually more targetted towards the frequently use models .

Before you commit on purchasing , is best to go their forums and watch out for models that are given more priority of updates.

for example, wifi6 series deco x20,x50, x60,x80, among this few, the X50 gets updated more frequently and comes with more new features ,but don't forget that this updates at times will introduce more bug breaking features .

source? Im using Deco X50.
