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.

r/TpLinkWhich deco mesh have dedicated backhaul channel?
9 months ago

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.

Hey! The TP-Link Deco M9 Plus and Deco X20 AX1800 are both solid mesh picks. M9 is super reliable, and X20 gives you Wi-Fi 6 and great coverage for 4,000+ sq ft.

Look at TP-Link Deco or Eero. Both are solid mesh options. With 2 floors and a basement, a mesh system with wired backhaul (if you can run Ethernet) will give you the best performance. You can always start wirelessly and run cables later if needed. Just make sure whatever you get supports Wi-Fi 6. It'll handle gaming, streaming, and working better than anything else.

get mesh system - depending on your current DL speeds that you are paying for you may get away with a pre WIFI 6 system of 2 or 3 units... they go cheap on FB market place where people have upgraded to faster speeds We have TP deco on a 3 story townhouse... 1 on each floor - works well no dead spots like we had before and can plug in apple tv in the lounge to one via a wire... not a massive outlay tbf for good coverage if you are looking for less than 100MB down Look for DECO MESH on FB market place and you may get 3 units of pre WIFI 6 for less than 100 bux... it does enough for less than 100 down
