Help ! I have my m8 android box connected to my plusnet router via Ethernet . Up until last week the box worked fine although the actual broadband would fluctuate on occasion. I have changed nothing at all . Now when I switch on the android box the internet stops to pretty much zero. The issue seems to be actually switching on the box. But weirdly unplugging the hdmi from the box the speed goes back to normal ?? I have tried different cables and it has the same effect . I'm baffled by this !!
