I have a Samsung TV model UN55D6005SFXZA. I have streamed Netflix and Pandora without a problem for two years. Suddenly, I an getting the error: Network Interference occurred. I have a Linksys router and all devices (computers and smart phones) work fine. I have reset the modem and router, verified all connections, even changed IP and DNS addresses. I have downloaded and installed all updates (firmware) ...nothing works. I have been getting the error for two days now. My Linksys dashboard says the TV is online. Help???
