No reason why it shouldn't work, its not a generic problem with the router as others are using it succesfully. Try a factory reset and start again using the quick setup.
I have a VR600 rather than VR2600 but I think the UI is similar.
Have you checked (under Advanced - Network) that the DSL mode is VDSL and the VLAN ID is 101? And the connection type is PPPoE? If you'd done all that and entered your PPPoE Username and Pasword as mentioned above, it ought to work.
(I know telling you it ought to work isn't necessarily very helpful ...)
