A:AnswerHello, I understand you want to know if the Xfinity channels are available on your Fire TV Stick 3rd Gen. I have great news the Xfinity app is available on your Fire TV Stick 3rd Gen. Hope this has addressed your concern. Have good one.
A:AnswerHello, Dmill!
There is an adapter that can be added to your Fire TV Stick that would allow you to use an Ethernet cable instead of connected the Fire Stick through WiFi. Once you have that adapter, you can plug the adapter directly into the Fire TV Stick and then connect the Ethernet cable. I hope this helps! Have a great day!
