I have a Virgin Hub 3 that's been working fine for months. Over the weekend, and with no changes on my part, it became unresponsive - no Ethernet or Wifi access and unable to log-in via the admin portal. I powered the hub off and on again, and normal service resumed... for about 5 mins. Then it hung again. I have now power-cycled it a dozen times, and performed both a soft and hard reset. Exactly the same behaviour - I can connect and use the hub normally for 5 - 10 mins, then it hangs again.
