I've used the S4 AC1900 trio (older but worked well), along with the X55 trio. Still Wifi 6 but decent coverage. The one failure was the Eero Mesh 6, stopped working but got a replacement set from Amazon and shipped the old set back. No problems since then.

We have the Deco system with Optimum and it’s great. We have 6 around the house and we get very good speeds everywhere. We have a pretty big house and the modem is at one end so the other end had horrible speeds even with an extender. Now it’s pretty much equal speeds anywhere you go.

We bought them at Christmas so we got a good deal on them or I probably wouldn’t have bought so many. During Covid my kids literally couldn’t connect or stay connected to the zoom calls because of the horrible internet speeds, before we got the Deco, as it’s an older house with very thick walls and it’s a ranch so it’s spread out. I don’t know what model we have but Deco has an app that monitors each unit, which we find very helpful. I would just look on Amazon and check the reviews for each model.

I found the one we bought on Amazon but I don’t see how to add a picture. They have a deal with three units for $89.99. If you search for Deco Mesh Wi-Fi it’s the TP-Link Deco S4 Mesh AC1900 Wi-Fi system

I took out the link and posted the name. The router connects to your modem with an Ethernet cable. Each unit has two Ethernet outputs so you can connect your devices with an Ethernet cable if you want it to be hard wired.

I like the TO Link Deco stuff My s4s will deliver around 400meg with no wired backhaul

It doesn't matter for 125mb tho, you can get 3-400 via wireless backhaul on the deco s4 for example

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.

They used to be really good but technology has moved on, I’d suggest looking at mesh systems, personally I use TP Link Deco S4s you can either just add them to your router and they spread the WiFi around the house or setup your own network which personally for me has faster speeds as the Decos manage the WiFi, has a very user friendly app as well you don’t need to be overly techy to make it work.

You can decide really, you mention your PC as an example you can have one in there and plug directly into the Deco, in the app you can see what devices are connected where, we live in similar houses by the sounds of it so I have one next to my router one upstairs and one near the back of the house to cover the garden.

Another +1 for the mesh system. I use the S4. No dead spots

I like my Tp link deco 400 unit. It can handle Wi-Fi 6 and Wi-Fi 6E

I have both deco's and cuddy's the decos you can get from costco though (3 pack) and they were pretty well but the bad thing is they kind of stop updating after a year or two. They also go on sale very often at costco. I am unsure on cuddy's as I just got them for testing. I also do bypass though so I don't even use the bgw620 even though I have one.
