I'm sorry to hear that, does this occur after power cycling the TV? Also are you using wireless or ethernet?
I too have this issue (exact same error message) Model QE55Q7FAM @SamsungCaleb
It's an ethernet connection to my router. I've powercycled the TV numberous times, I've upgraded the firmware to the latest 1280.5 but still get the same message.
