Secure Your Wi-Fi Router
When it comes to securing a Wi-Fi router, there are a lot of things people often do that aren't actually effective. For instance, hiding the name of the router (the SSID), won't help. Another scheme that's particularly onerous is MAC address filtering. Every computer has a unique MAC address, and the router can be set up to only allow computers with known MAC addresses to access the network. This technique is used by businesses and schools, but it overlooks MAC address spoofing.
