How can I secure my WiFi router?

Episode 1684
Bruce fromBruce wants to know how he can secure his WiFi router. Leo says to first enter the router address (198.x.x.x) and then change the default password. Then, turn off Administer via WLan. This will prevent someone from the outside controlling your router. Step 3, turn off UPNP (aka universal plug-in play). This prevents a device inside of your network, like an Xbox, opening up your router to the internet when you don't want it to. Lastly, turn on WPA2 security encryption.
