Hi,
I have Deco XE75 installed. It is fine where it reaches, but this is an old house in the wilds of France, and my house has walls of around 1.1m thick on the ground floor and 80cm on the next floor (1st floor in the sensible system, 2nd floor in American), so it doesn't reach anywhere easily. The top (2nd) floor is currently unused.
The distance between my office on the 1st floor and the kitchen on the ground floor is around 50m with three walls of average width of 1m between the two points. Because of the difficulty of getting a signal across that without putting a satellite in my bedroom (Which is an absolute no-no, according to my wife) I am thinking of putting in a powerline adapter to get a signal to the kitchen. I would like it to connect to the mesh satellite in the room above the kitchen, which should give me WiFi into the rest of the house.

Ethernet is not an option, the walls are made of river rocks cemented together, so there's no direct line through for a drill, the hallway doesn't have any skirting, just a flagstone floor, and I don't want ugly. I can't string ethernet outside the house for the same reason that my window shutters and front door are made of oak; the weather here can be frightening. It's also a long way up with a cobbled courtyard for my ladder to rest on.

It's not straightforward, as I have three routers for various reasons, but I just want the 'main' system to be accessible throughout.

To be fair any powerline adapter would get decent enough WiFi in the kitchen, but if I can get the mesh to connect to it, I can get usable WiFi in the whole house without buying another two satellites.

So, a simple question, would a TL-WPA8631P Kit do the job? If not, any ideas as to what will? I am pretty technical, but a unix guy, not a networks wonk, so I don't need anything I need to spend weeks on.

Thanks in anticipation.
