I cant seem to find the answer to this.

Im looking at purchasing the Deco X1500 or 50. I have a sliightly non-standard requirement.

I'm happy with the in-house set up but i also have a garden office (about 15-20m away) which already has an ethernet cable pre-run. Im looking to have the same wifi throughtout. Can 2 deco devices be connected via ethernet? It wont be the device that connects to the router which will be cabled together.
