Why Is My Xbox Saying UPnP Not Successful?

The Xbox makes use of a feature known as Universal Plug and Play, or UPnP, in order to configure your network for multiplayer gaming and chat. Whether the message "UPnP Not Successful" appears in the network settings of your console, the first thing you should do is check to see if your router requires an update. You should then save your settings after turning off the UPnP configuration. Perform a restart on your gaming console, as well as your modem and router.
