Ok, I am so confused about moca and I need help! I want to buy one, so I can use the stream one day, but im really confused. I have a room in the basement. The router and modem are upstairs and there is no way to get an ethernet cable down to the basement or reach the modem or router. I have comcast, and one little cable outlet thing behind my tv setup. from what I am understanding, can I buy a single moca adapter, plug it into my tivo, and then connect the coax cable from the adapter to the wall? is that how it works. please explain it relatively simple. I'm no good at networking! thanks so much!
