Before I try I wanted to check. I want to extend the network to a room upstairs. WiFi is fine, but I need a hardwired connection. Since I have Xfinity service can I use just one of the Actiontec MoCa adapters? There is Coax in the room already. Or do I need tw of the Actiontec pieces? One for injection and one on the receiving side?
Just wanted to check. Thanks!
