N750 Wireless Dual Band Gigabit Router WNDR4300 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 router does not allow
any device to automatically control the resources, such as port forwarding (mapping),
of the router.
• Advertisement Period. The advertisement period is how often the 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 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 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.
