Create a white list for your Livebox

If you subscribe to Orange Internet and use a Sagem modem, a WEP (Wired Equivalent Privacy) security key will be provided and required during the installation procedure. This allows you to connect your computer to the WiFi Livebox so that you can access the Internet from wherever you want in the house. This precaution allows you to prevent anyone from accessing your wireless network and using your internet connection.

The only problem though is that if anyone discovers this security key, then your wireless network will once again become accessible. To prevent this eventuality, you can create a white list so that you can define which computers can access the wireless network or a black list to prevent certain computers from ever getting access. The first solution is the simplest to implement, as the number of computers that you know of will not be many. So we will be implementing this solution.

This filter is implemented with the help of the network cards physical address, also known as a MAC address (Medium Access Control). This is a serial number made up of 6 hexadecimal values, with each network card having a unique number. For example “FF:FF:FF:FF:15” To find your MAC address, you can read it off your card (for a PCMCIA or USB card) or by requesting the information from a command prompt (for internal network cards).

Click on the start menu and click on “Run”. In the box that appears, type “cmd” and click on OK.

Once you are at the command prompt, type the command “ipconfig /all” and press enter. Information about your network card will be provided. You will then need to look for the wireless connections and the “Physical address” which will have the corresponding serial number noted next to it.

Do the same thing on all computers that you want to give access to your Livebox to.
