DM200: Error: Network device is not present

I am using zen.co.uk ISP in England. They provide a PPPoE connection.

When I start the DSL connection from the web interface, I have the following error:

Error: Network device is not present

From the terminal, I have the dsl0 interface, but with the NOCARRIER error on the dsl0 link.

Anyone has an idea ?

Not the same device, but following https://openwrt.ebilan.co.uk/viewtopic.php?f=7&t=266 should give you the necessary information, as the dm200 is also a lantiq vr9 device and behaves very similar.
