Can someone tell me the proper way to hook up a cable modem, tuning adapter, and tivo using the same outlet. I recently moved the cable modem/router from one room to the same room as the roamio. I had very few problem with tuning problems with the cable modem in another room, now with it on the same outlet I am receiving quite a few more tuning issues. It comes out of the wall into a two way splitter. One end goes into the tuning adapter and uses the pass though to go to the Tivo. The other end is going into the cable modem/router. Is that the correct way or am I missing something?
