Hi,

There are some mesh products, like Deco M5, Deco M9 plus and so on. 

You can use it to create a mesh wifi system to extend the wifi range, while the Deco products is a regular wireless router by default, it can work as an access point to extend wifi as well. 

Here you can get more information: https://www.tp-link.com/home-networking/deco/

Have a nice day.

Can anyone advise on adding mesh repeaters to extend the effective WiFi coverage in my home?
