Ziggo (or UPC) is a cable company in Europe that offers internet over cable. One of the DOCSIS modems they offer is the Compal CH7465LG-ZG, or Ziggo Connectbox. This post describes where the screws are and to open the modem enclosure to get to the hardware.

One screw in the back

On the back there are the network ports and the cable connection. The grey area with the text on it is a sticker. Peel that back to reveal the screw hole next to UTP port 4. The screws are security torx, size 10.
