Hi @rwdm,
Welcome to our community forums and thank you for your first post.
Sorry to hear you are having an issue with your hub light. We can understand your concern and we want to best help. Just to confirm, is your hub in a well-ventilated place? Also, does the red light remain after rebooting the hub? https://www.virginmedia.com/help/broadband/reboot-or-reset-hub
