If you are not going to use the wireless capability from your broadband router, you must disable it, otherwise hackers will be able to easily access your network using a computer with a wireless network card.

The exact name and location of this option will vary according to your router manufacturer and model. In our case this option was available under “Wireless,” “Basic Wireless Settings,” “Wireless Network Mode.” In theory this option configures the wireless network mode (i.e., speed), but it also presents an option called “Disabled,” as you can see in Figure 3. After selecting this option, simply click on “Save Settings.” Of course if you want to have a wireless network you need to keep this option configured with the wireless mode (speed) you want to use.
