Ok thank you for that information.
On the Device Configuration page of the Obi website next to Service provider 1 (SP1) it said resolving DNS. That has since changed to connected and everything is working fine again.
BUT, when I try to log into the OBi, when I enter admin / admin it will not take it. I just get the password window again and a note that says :the server 192.168.0.184 at admin@OBi110 requires a username and password" Could there be a different username and password? I have not changed it.
