No internet, error: the broadband physical link is down

Hello,

I have the following error: the broadband physical link is down. I have gone through all the steps via the website to find out the problem. I reconnected the cables and restarted and reset the modem. This is an Experia Box V10 modem 

The orange light is on for services. The computer connects to the modem normally, ie the network does appear on my computer. 

How do we solve this?

Thank you!
