Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, 
to access the network and connect to other devices as needed. UPnP devices can 
automatically discover the services from other registered UPnP devices on the network.

If you use applications such as multiplayer gaming, peer-to-peer 
connections, or real-time communications such as instant messaging 
or remote assistance (a feature in Windows XP), you should enable 
UPnP.



Select ADVANCED > Advanced Setup > UPnP. 

Configure the following settings:

Turn UPnP On. Enable or disable automatic device configuration. The default setting 
for UPnP is disabled. If this check box is not selected, the WiFi DSL modem router 
does not allow any device to automatically control the resources, such as port 
forwarding (mapping), of the WiFi DSL modem router. 

Advertisement Period. The advertisement period is how often the WiFi DSL modem 
router broadcasts its UPnP information. This value can range from 1 to 1440 minutes. 
The default period is 30 minutes. Shorter durations ensure that control points have 
current device status at the expense of more network traffic. Longer durations can 
compromise the freshness of the device status, but can significantly reduce network 
traffic.
