Go unifi my guy. Used to use the deco m9 plus as well. Literally don't have to reset my router. Stable connection. Don't forget to add a rack and make everything pretty.

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.

Yes. More control is better. With Unifi you can actually see what's going on with your network. VLAN partitions are amazing. With Unifi I find I move between APs way better. With TP Link I found I was often stuck to an worse AP. I'd drop my wifi and reconnect regularily. I don't do that anymore.

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.

Depends on what you want. Do you want future proof WiFi 7, an more options to control? I’ve had mesh systems from Linksys, tp link, net gear and honestly I’ve found tp link is great. They’re kind of lax on the updates but functionality wise, great system. I have my moms place on the deco be 85s and all 3 are wired back hauled. If you want wireless back haul consider maybe a deco 95. What is the sq ft of the house? How many stories? Do you need service out in the garage if detached? In my semi truck I’m running the deco be65 outdoor since it’s built for weather and harsh environments. But like I said it all depends what you want to do with it or if you like to customize. To me the app is great. You can see what each device is pulling in terms of data

I've used and installed TP-Link Deco Wi-Fi. M9Plus, M5 and S4. All have worked great. Those are comsumer products. You can go pro-sumer and get TP-Link Omada. I use this in my house currently. Outside I use eap225-outdoor and indoor I use eap720. You can get PoE switches where you need more ethernet ports. If you want/need fast roaming you'll need a controller like an OC200. You can also go cloud based, but I don't recommend that for more than one eap. In reality Omada isn't too expensive, the eap720 was on sale for 80 dollars on Amazon and the eap225-outdoor is 70 dollars. The eap225-outdoor is dual band AC1200 (Wi-Fi 5) and the eap720 is dual band BE5000 with Wi-Fi 7.
