I think I have a hub 3.0. The internet light is intermittently flashing green and red. The Wi-Fi light is on permanently. I have no internet connection, but devices can connect to the router fine. Virgin media says no faults in my area. This has been going on for two days.
Welcome to our forum, I am sorry you are having problems with the connection. We would like to help however I am unable to identify you from the forum details. I will send you a forum private message to gather some more information.
