Universal Plug and Play

Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, 
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.



Select Advanced > UPnP to display the following screen:

Fill in the settings as follows:

Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration. 
The default setting for UPnP is enabled. If UPnP is disabled, the modem does not allow 
any device to automatically control the resources, such as port forwarding (mapping), of 
the modem. 

Advertisement Period. The advertisement period is how often the modem advertises 
(broadcasts) its UPnP information. This value ranges from 1 to 1440 minutes. The default 
is 30 minutes. Shorter durations ensure that control points have current device status at 
the expense of additional network traffic. Longer durations might compromise the device 
status freshness but can significantly reduce network traffic.

Advertisement Time To Live. This is measured in hops (steps) for each UPnP packet 
sent. Hops are the number of steps allowed to propagate for each UPnP advertisement 
before it disappears. The number of hops can range from 1 to 255. The default value is 4 
hops, which works for most home networks. If you notice that some devices are not being 
updated or reached correctly, you might need to increase this value a little.
