Mysterious problem with a patch panel...?

Hello,

Looking for help.  

I moved into a house with an existing patch panel.  I am trying to get it to work with a cable modem.  The cable modem connects perfectly when a regular patch cable is connected to the network jack of the modem, to the Ethernet port of a computer.  

This is the modem:

I connect the modem via a patch cable to the patch panel:

And then connect the corresponding jack in the house to a computer with a patch cable.

*I get no connection*

I have tried patching the modem cable directly to each port in this patch panel, and nothing.  I have used regular patch cables, and crossover cables, with no luck at all.

I have come to the conclusion that the patch panel itself must be bad, or the cabling is cut somewhere else (very unlikely).

Thought I would ask this question to see if anyone had any ideas.

Thank you.
