Hub 3.0 Keeps Rebooting

  • Hey everyone,

I've had serious issues with my Hub 3.0 router today. It has been constantly rebooting itself every few minutes for more than 16 hours now. 

I've tried rebooting, checking connections and running VM online diagnostic tools. Nothing has worked.

When the router restarts our Internet does work for like 5 minutes but then the whole thing reboots and the whole circus begins again. 

I've also tried Virgin Media support via phone and live chat but have been left without answers or on hold for hours without any advice or help. So now I'm here! 

Here are a few lines from our Router Status page, hopefully they help.

Re: Hub 3.0 Keeps Rebooting

Your downstream levels are too low.

Is there an attenuator fitted to the back of the hub?

Re: Hub 3.0 Keeps Rebooting

Unless there’s an area issue you’ll need an engineer visit.
