Installing an Internet-Box in a home with existing network cabling

Installing an Internet-Box in a home with existing network cabling

Larger, more modern homes have a network cabling socket in each room. Benefit: You can plug in your PC or PlayStation in that room and you enjoy an excellent signal. Find out here how to position and wire your Internet-Box to do this.


If you want to use your existing home cabling, place the router adjacent to or inside the wiring cupboard*. This will send the DSL signal from the wiring cupboard straight to the Internet-Box, and from the Internet-Box to the LAN sockets in each room. Proceed as follows:

  1. Connect the DSL cable supplied with the Internet-Box (purple plug) to the telephone port (U interface) in the wiring cupboard and to the “Internet” port on the Internet-Box.
  2. In the wiring cupboard, connect the network port (yellow slot) on the Internet-Box to the LAN connection of the room in question. To do this, use a network cable (yellow plug). Repeat this for all the rooms in which you want to use the signal direct from the socket.wiht_network_cabling.png

* Usually made of metal, wiring cupboards are not located centrally in the home. This means that if you place the Internet-Box 3 or Internet-Box standard inside the wiring cupboard (using the wiring cupboard kit, available to order from the end of April for CHF 39.–), be aware that the WLAN signal may be weaker. In this case, use an additional WLAN-Box to amplify the signal. The WLAN-Box can be connected to the router using existing Ethernet cables.


Our recommendation:

Use the procedure above if your home has a fibre-optic connection.


Professional assistance

If structured cabling is to be used, adjustments may be required by an electrician or Swisscom engineer (charge applies). They will use additional cables and change the existing multimedia socket if necessary. An additional Ethernet switch in the wiring cupboard also enables the continued use of existing multimedia sockets. Go to home installation services


Without home cabling

If you do not want to use pre-existing home cabling, position the Internet-Box as centrally as possible in your home and use the following cabling procedure:

  1. Connect the DSL cable supplied with the Internet-Box to the “Internet” port and the closest network socket in the room.
  2. Connect the relevant network port (LAN 1) in the wiring cupboard to the telephone port (U interface). To do this, use a network cable.wihout_homecabling.png

Our recommendation:

If the WLAN signal from your Internet-Box does not reach all the areas of your home, use a WLAN-Box to enhance the signal.
