Several times over the past two months my superhub has failed. The top blue light and the bottom green light stop flashing and go out, when this happens i am unable to connect to the internet either wired or wireless. When i unplug the power and plug it back in it reboots and everything is ok again. I am a bit concerned that the hub is on its way out and will fail completely at an inconvenient moment. Is this something that happens from time to time or do i need a new superhub?
I'm sorry to read that you are experiencing issues with your broadband connection.
I've managed to locate your account and the upstream power levels are on the high. For this I would like to arrange an engineer appointment to take a look at this. I've sent you a PM (purple envelope icon, right corner) requesting some details.
