HI.

Should green DSL light concern me? Cause manual says that connection is syncronising when light is flashing but does not mention that tere are two colours, amber and green.
Seems to me that DSL light flashes amber when connection syncronising and changes to green when is synchronised but still flashes.

Doeas anyone know anything about it?

Thanks.

The function of the DSL LED changed a few firmware versions ago, now it blinks green when connected to indicate activity. Orange blinking indicates it's connecting / syncing up.

It looks like the quick start guide has been updated in July this year in .pdf form to include that change.
