What it is: It'll give you a single Wifi Network across your property. 'Wifi boosters' force you to have multiple networks to join. My TP Link Deco plugs into my router, and is my 'main' wifi network. The router still puts out a network, but nothing uses it. Other benefits - their software (apps) are great and you can whip up guest wifi networks easily, or networks for use by 'suspicious gadgets' that need the internet, but you don't want them on the same network as your phone and PC. We've got 3 nodes in the house - one in the router, then two upstairs. You might get away with 2. I've got the M5s, but maybe the S7 (AC1900) might be a good fit - [https://www.amazon.co.uk/dp/B0B8DXJ8XP?th=1](https://www.amazon.co.uk/dp/B0B8DXJ8XP?th=1)

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.

I ditched the Spectrum router and connected directly to my Mesh router. Works awesome. https://a.co/d/eQkmmO0

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

I use deco pods. One on each floor, I use MoCA to use coax as the backhaul, but Ethernet is good as well.

I use Deco pods with a wired MoCA backhaul.

There really is no one Wifi router that will penetrate all walls and building materials and give you a giant bubble of Wifi. As far as signal strength goes, they are about the same. For the best experience on a budget and easy to set up, mesh is typically the go to, like Deco or Eero. Running a wire between the two or more for wired backhaul will make it even better better.
