Configure Universal Plug and Play
Universal Plug and Play (UPnP) helps devices, such as Internet applian\
ces and computers, 
access the network and connect to other devices as needed. UPnP devices \
can 
automatically discover the services from other registered UPnP devices o\
n the network. With 
UPnP, you can specify the following:
•Advertisement period. Specifies how often the modem router broadcasts its UPnP 
information. 
 The default is 30 minutes. Lower numbers ensure that control points 
have current device status at the expense of more network traffic. Larger numbers 
compromise the freshness of the device status but can significantly redu\
ce network 
traffic.
• Advertisement time to live. 
 The time to live for the advertisement, measured in hops 
(steps) for each UPnP packet that is sent. Hops are the steps a packet\
 takes between 
routers. The number of hops can range from 1 to 255. The default value for the 
advertisement time to live is four hops, which should be fine for most h\
ome networks. 
If you notice that some devices are not being updated or reached correct\
ly, you might 
need to increase this value slightly.
To configure UPnP:
