@ General Maximus , you are right its the Amazon fire tv box that is causing the ports to switch off and then i have to use wifi .

i have 4 of these boxes , one is fine with the dns , so i dont think its the dns thats a problem , one causes ports to switch off and i havent had time for the other two yet . thanks
