Hi jbrennand,
Thanks for the reply, apologies for the late response.
On WiFi it just stops, sometimes after a minute it will come back on or restart WiFi on devices, but most of the time the hub has to be restarted. When I have run the diagnostic tool it details that all WiFi devices are to far away even the device I am checking it with from 6ft.
The ethernet also goes as I have a sky box connected via ethernet and my has told me when the WiFi goes down it effects the sky box also.
Thanks in advance
Gareth
