Help please I have just brought this router, I have a Google mesh system but if I can just use one system it would be better, however I am confused as which extender I should buy or should I buy the mesh system?, also I have a large area to cover with thick walls the Google system allows me to extend the system by adding hubs, I read the tplink extenders boost from the router not from extender to extender.

can someone please tell me the actual truth of the matter and what should I get or keep the Google mesh.

thanks
