I had to reset my Mediacom internet password last week. Now I can't get Netflex. I think I need to reset the password on mt TV as it has the old one the tech set up upon install. I don't have a satellite signal and have not for a week now because the dish sank. They are coming out Monday but I want to watch Netflex that does not require a Satellite signal. Can you tell me how I reset this?
