my house, built in 1983, has in wall rg 59 to tv access. I cannot get all channels from Verizon and they tell me that it is because my in house cable is antiquated. I am agreeable to updating to whatever is necessary (cable rg6, cat 6, etc) to be compatible with current requirements but I am completely confused as to the best way to go. Any recommendations? I would hire an electrician but want to be as knowledgeable as I can.
