A:Answer No, you have to connect the wall coax to a two way splitter and from the splitter connect your modem as well as your moca adapter. Once that’s done, connect your moca adapter to your router using an Ethernet cable and that will send internet through the coax in your home. Then, simply connect the other moca adapter to the wall coax in the room you’d like to receive the internet signal and from there connect any Ethernet capable device.
