To explain my situations: I ordered kabel internet from O2, they say the activation can be done without a technician the only thing I had to supply was the MAC address from my kabel modem, what is the Fritzbox 6690.
With the fritzbox connected it seems there is no signal, so the light keeps blinking. Even we tried a COAX signal checker and it seems that there is no signal on the kabel. This can happen because it is a new building.
So there is an ticket and they say it will be fixed today, but no status update so far
