Universal Plug and Play (UPnP)

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. With
UPnP you can specify:
Advertisement Period. This specifies how often the gateway broadcasts its UPnP
•
information. The default is 30 minutes. Lower numbers ensure that control points
have current device status at the expense of additional network traffic. Larger
numbers may compromise the freshness of the device status but can significantly
reduce network traffic.
Advertisement Time to Live. The life of the advertisement, measured in hops (steps)
•
for each UPnP packet that is sent. A hop is the number of steps that are allowed to
propagate for each UPnP advertisement before it disappears. The number of hops
can range from 1 to 255. The default value for the advertisement time to live is 4 hops,
which should be fine for most home networks. If you notice that some devices are not
being updated or reached correctly, you might need to increase this value slightly.
Select Advanced > UPnP.
