@Bobrovsky Alright, thanks for the reply. There is a fair amount of concrete In between so I'll use the powerline just in case. Anyway I think the router will switch to the fastest config. I'll off...

I am considering purchasing the Deco x20, but I am not sure if it can be used with the pre-existing power line adapters in my home. Here is a diagram of my ideal set up, will it work? Thanks!
