Hello guys,

I do not know much about networking and general but I just finish setting up mesh wifi with TpLink Deco x60 through the app. They works just fine. But since we have 5 floors and the 3 devices can only cover 3 floor, I would like to use another device to cover 4th floor and just a little bit of 5th floor. Will Archer x73 solve my problem? And can it mesh with my Deco setup?

Also the store tell me that I need to buy another set of Deco x60 because the Archer x73 will not work in mesh. And also having ethernet cables plug into all devices will make the mesh devices stop working?
