Still having an issue?
You should have 3 lights on the openreach router
1)Power
2) DSL
3) Lan1/lan2
now if all 3 are solid green your connection to the openreach router is all working fine but if any are flashing apart from lan light you have a problem that will require thorough diagnosing
Hope you have it sort and this message is not needed

You can test the modem by plugging a PC directly into it and setting up a PPPoE connection.
There's a guide here for Windows 7
