I did make sure of the credentials, and the log of the router shows that authentication is indeed successful. The authentication is set to Auto, and values of VPI, VCI, MTU and Timeout are the same as you described.
As for the DSLAM port, I highly doubt it's faulty because all my neighbors seem to have normal internet connection. However, I will try to use one of their modems and report back.
I really am frustrated with whatever trick Ogero is pulling on this one :/
Each user has a different port assigned to. You cannot have two users on a same port. My suggestion is to try a neighbors router on yours, and it should be an ogero one. Also, you may try yours at their place if you want.
Try this before buying a new router. Good luck!
