Downloaded Desktop streamer, however I am unable to stream to the television. I am trying to use WIFI.
What Desktop streamer did you download?
For comcast, you should be using the xf streaming web site: https://tv.xfinity.com
If you connect your puter to the tv with a hdmi cable, the tv would be like your monitor.
adding.... I stream to my TV from my desktop using a Chromecast dongle and the Chrome browser.
