Hi Alleyoop, first, allow me to clarify the service call fee. If you schedule a service call and the issue is found to be in Cox-owned equipment or outside your home, there will be no charge for the service call. Now, allow me to get a better understanding of what is happening. Is your Roku/Smart TV connected to your home network wirelessly, or wired via an ethernet cord to the router? Do you experience a loss of connectivity on all your internet-connected devices (computers, cell phones, tablets, etc.) when you have streaming issues on your TV? -Becky, Cox Support Forums Moderator
