My hub has been doing this for months now, consistantly randomly cutting wifi and dropping all connections in the house, this isnt due to an overload on the wifi, simply can be only me connected at night and boom, drops for hours at a time. Went through every single step to get this sorted, even had an engineer come, who accidentally then broke my ethernet cable too, so i had to buy a new one, no complaints considering i thought the problem was fixed, but this has happened far to much now, i was on virgin media before hand this only happened once in two years with them. The main problem i assume is that there is somethiny wrong with the wiring, the middle light remains a solid yellow state for hours apon end, allows all devices to connect but displays "no internet" includiny wired devices like my pc.
