Home Wireless AP suggestion

[crudler]

I have a TPLink TL-WR840N that is linked up via an Ethernet cable running from my main router in the other side of my house.
the TPlink isnt the greatest (freeby that I got from an ISP at some time, but it did the job when I was in the same room).
I am moving my home office a few rooms away, and the Wifi is obviously weaker.

I want to beef up the Wifi in this side of the house. I dont want more extenders, or to run another cable.
I'd rather replace the TPLink with something meatier that gives me better coverage.

Suggestions?

Just note this doesnt need to connect to the ISP, its just a wifi AP


Thanks!

EDIT: I'm not a network guru, so something simple please

Mesh kit will give you a way better home wifi experience

sure, but im not looking at a full on change in infrastructure.
right now i just want to pull out a small AP, pop in a bigger AP

This will give you better coverage https://scoop.co.za/tenda-2-4ghz-6dbi-4-port-fast-ethernet-router-and-repeater-f9.html

Its also 11n being old tech, but has much better range. This is the simplest, best bang for buck option

Its one of the few things Tenda did right.
