I can't install my router to my access point

 
Hello,

I am facing installation issue: my fiber connection looks like the one in the pict. I can’t connect the black box kpn has sent me. How should I do?

can you please support?

It is better to open a separate thread instead of hijacking someone else’s.

On your picture a coax outlet is shown, which is not the connection for DSL or fiber. If you could order a KPN subscription, their administration indicates that there is a DSL (telephone) or fiber connection at your location. Mostly located in the cupboard with the electricity meter. Have a good look around.

If you can’t find it KPN will have to send a technician.
