How can I secure my wireless network?

Episode 967 (2:00:22)

John from South Bend, IN

John wants to secure his wireless network, and is wondering if he should set it up with MAC addresses. Leo says MAC addresses don't really do anything. He recommends setting up the router with WPA2 (NOT WEP) encryption and give it a good password with alpha and numeric digits. He should also set the SSID for something that is easy to remember (Leo uses dead rock stars).
