SuperHub3 Randomly Rebooting

Hi there

We have a SuperHub3 which just recently has started to randomly reboot. Tend to mainly notice this when working from home during the day. Not sure if it's a hardware or software issue but the network log is shown below:

      Hi bazzajok 
      Welcome to the Community Forums. 
      Sorry to hear of your concerns with the router rebooting. 
      Checking the systems on our side, we cannot see any issues affecting the services at this time. How was the service over the weekend, or since posting? Has the issue continued?
      If so, can you start a broadband quality monitor to see if we can find any pattern or issues in this to assist further? You can raise this here. Post your live link on the graph here, and we can monitor this alongside you.

        Thanks for the reply. I haven’t noticed any reboots whilst at home but I will keep an eye on things. It’s definitely a random occurrence rather than a scheduled reboot. 

        Thanks
