N750 Wireless Dual Band Gigabit Router WNDR4000 User Manual 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. 1. Select Advanced > UPnP to display the following screen: 2. Specify 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 wireless router does not allow any device to automatically control the resources, such as port forwarding (mapping), of the wireless router. • Advertisement Period. The advertisement period is how often the wireless router advertises (broadcasts) its UPnP information. This value can range from 1 to 1440 minutes. The default period 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 freshness of the device status but can significantly reduce network traffic. • Advertisement Time to Live. This is measured in hops (steps) for each UPnP packet sent. Hops are the 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. • UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each UPnP device that is currently accessing the wireless router and which ports (internal and external) that device has opened. The UPnP Portmap Table also displays what type of port is opened and if that port is still active for each IP address. 3. To save, cancel your changes, or refresh the table: • Click Apply to save the new settings to the wireless router. • Click Cancel to disregard any unsaved changes. • Click Refresh to update the portmap table and to show the active ports that are currently opened by UPnP devices. 80 | Chapter 7.
