Configure 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. 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 reduce 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 home networks. If you notice that some devices are not being updated or reached correctly, you might need to increase this value slightly.
To configure UPnP:
