A:Answer I believe you can connect an adapter in any room that has a coax cable jack. I connect one adapter to my router and to the Comcast splitter that comes into the house. By connecting it here, it distributes a Ethernet signal over coax to every coax jack in my house. I then have another in my bedroom to hardwire my Roku and Apple TV, as well as another in my living room to hardwire the devices there. As far as speeds go, I have a ton of devices connected to my network and after doing speed tests, the devices on each coax adapter are running the same speeds. Hope this helps
