I'm trying to use a firestick on a Hitachi rear projection tv. I cut the cord with Dish and would like to use with a firestick. I am using an HDMI to AV converter with a firestick plugged into it and have been able to connect to my range extender. I have signed on to my network and it shows connected with a strong signal but no internet. My small brain can't get past this last hurdle.
