I've had the Hub 3.0 now for a couple of months, no issues. However, last night it seemed to stop functioning. It is no longer transmitting a wireless signal. The white light alternates between flashing and steady, but never stays steady.
I've tried turning it off and on and resetting it via the reset button. It is still doing the same thing. No faults in my area according to Virgin, but I assume any faults wouldn't cause the wireless portion of the router to stop functioning anyway. A test on my account suggests my device might be turned off.
