Sorry that you're experiencing problems. When you are trying to access the configuration pages are you doing so using a direct wired connection?
If you are and you're still encountering issues logging into your Superhub please perform a pinhole reset on it and try again. If you've done all of this and the error continues, please post again so that we can investigate further.

------Die-hard direct connection modem user---Because newer is not always better Super hubs 1, 2 & 3 could have been built better the years go by and we can't see the mistakes that were made to make things right. Use modem mode If I could offer you only one tip for the future, modem mode would be it. BQM, Outgoing ports test
