Not sure what you mean by streaming off of your Xfinity box. Typically, the Roku stick will connect wirelessly to your wifi network. If the Roku units are old, I would suggest upgrading them and buy Roku sticks that will plug directly into an HDMI port on your TV. The Roku remote control also uses wifi to control the Roku stick. It may be helpful if you can post the model number for the Roku units you are using and how they are connected to your TVs and/or Xfinity box.
