I've got a Deco X10 and two M9 Plus covering three floors of a house. Works great for me. They're decently powered devices, each running about 8-10 WiFi clients including two TVs streaming simultaneously.

Used Deco M9 would be the ideal solution as they have a dedicated wireless backhaul as well as two normal wifi channels giving you a WIFI 5 with a separate backhaul. Being a few years older, they are also cheap on the used market for what they can do.

I have deco m9 plus and it has a dedicated 5 ghz for thr backhaul and therefore its called a tri band router. Even I am looking to add a couple more to the network as I am planning to shift one to another site. But I dont know which new ones have a dedicated back haul radio.

Another vote for the deco. I have 2 M9+. Working perfect. Fist bought 3, but 2 was more then enough.

Seconding TP-Link Deco. I've got a hybrid set up of M9 and M5 units (including one M5 in a detached garage) that's been rock solid for years.

Invest in a mesh system , ideally triband ( so dedicated wireless link between units. Previously had a Deco M9 ( can be picked up cheaply ) . Had 3 of them linked in a 3 storey house and was spot on for speeds up to 500 mbps. Easy to use app. Upgraded to a ASUS mesh now due to 1gb fibre .

Not true. The M9 Plus - which is a very old Mesh router, has a dedicated 5GHz backhaul channel radio.

YES. The Deco M9-Plus has a dedicated 5GHz backhaul radio. I do wish people would spend 5 seconds checking before guessing an answer! The M9-Plus is a fantastic little router. It even acts as a VPN client, and can create dedicated sub-nets for Smart appliances at a click of a button.
