Find SECURE Sites

While limiting access to your 192.168.1.254 Wi-Fi net by MAC address is a good idea (every computing device has a unique MAC address, usually printed on a label on the bottom along with the serial number), there are two big problems with relying on this security method alone. First of all, since WiFi signals are simply radio waves, they can be read by any receiver without needing to be connected to your router. So if you don't use encryption, the data you transmit and receive wirelessly is sent in plain text for all to read. Second, MAC addresses can be spoofed. That is, someone can read your MAC address as it is sent over the air, and then pretend to be you, connect to your router, and gain full access to your 192.168.l.254 network. It's always best to use every layer of security available to you, from system-level approaches like personal firewall and antivirus software, to router-based functions like encryption, closed networks, and MAC address limitation, as explained in our Guide.
