Can anybody help? My father has been having lots of issues lately with his broadband. The router is upstairs. Tv is downstairs. He streams Netflix and amazon via a PS3 and the broadband is 100mb. It was working ok but lately it’s been really bad. Constant buffering. I have turned the router off and on and it hasn’t made any difference. He maybe gets 5-10 minutes viewing and then it buffers from anywhere from 10 seconds to a few minutes.
