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

Look at firewalla gold pro ... Best router I've ever used in a long time... Understand this is a router only though... This doesn't provide wireless access and way above your budget . Would also need to add access points for that. I don't think you will find anything decent in that price point TBH. ... I had decent luck with TP link deco as well but I find that it could have some better features... Unfortunately if you go with consumer routers you will always find them lacking....

\+1 for deco, I have 3 of them at home (one on each floor) and it works great!

Don’t bother with TP Link Deco either, ok router but not great Parental Controls.

I only have the Deco so that’s all I can speak to. Ive been really happy with it. Easy to set up, works really well, and no issues after over a year so far. It has all the capabilities you would want, including easily setting up separate networks for guest, IoT devices, etc. you can assign your devices to specific access points or use the mesh functionality. Also very easy to expand if you want to add more access points.

I have a TP-Link Deco mesh system that was easy to set up and easy to expand. No issues so far for 2 years

Wifi extender would reduce the speed considerably. Best option : Mesh network. You'll need two minimum and add on would be 2.5K per mesh router. TP link Deco is what I am use. Second best : buy another wifi router and connect it with the original through ethernet cable. You'll have a different wifi name for the network from the second router so you'll have to switch between connections.
