Enabling Universal Plug and Play (UPnP)

Universal Plug and Play (UPnP) can improve the overall networking experience through automatic
discovery and device interoperability. 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.
By default, UPnP is disabled. When disabled, the router will not allow any device to automatically
control the resources of the router, such as port forwarding. When UPnP is enabled, you must set
the Advertisement Period and the Advertisement Time to Live according to the following criteria:
• Advertisement Period. Determines how often the router will advertise (broadcast) its UPnP
information. This value can range from 1 to 1440 minutes. The default period is 30 minutes.
Shorter durations will ensure that control points have current device status, but this can create
additional network traffic. Longer durations may compromise the freshness of the device
status but can significantly reduce network traffic.
