Hi Meg_n ๐ Thank you for your post and welcome to the Virgin Media Community ๐
We're sorry to hear about the problem you're having ๐
If it's a Hub 3, please follow the below steps in the following order:
โข Turn the power switch off on the back of the Hub
โข Ensure the Hub is upright, in a well-ventilated location, and, if at all possible, out of direct sunlight
โข Use the power switch to turn the unit back on
If after following the steps the router doesn't boot back up after a few minutes, or the red light returns when it does, it'll need replacing.
Please pop back to us at your earliest convenience.
Thank you for your support Tudor ๐
Regards,
Daniel
