- A. Supplemental Information
The BASIC Home page displays.
4. Select ADVANCED > Advanced Setup > UPnP.
The UPnP page displays.
5. Select the Turn UPnP On check box.
By default, this check box is selected. You can disable or enable UPnP for automatic
device configuration. If the Turn UPnP On check box is cleared, the router does not
allow any device to automatically control router resources, such as port forwarding.
6. Enter the advertisement period in minutes.
The advertisement period specifies how often the router 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 detect current device status
at the expense of more network traffic. Longer durations can compromise the
freshness of the device status but can significantly reduce network traffic.
7. Enter the advertisement time to live in hops.
The time to live for the advertisement is measured in hops (steps) for each UPnP
packet 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 4
hops, which should be fine for most home networks. If you notice that some devices
are not being updated or reached correctly, it might be necessary to increase this
value.
8. Click the Apply button.
The UPnP Portmap Table displays the IP address of each UPnP device that is accessing
the router and which ports (internal and external) that device opened. The UPnP
Portmap Table also displays what type of port is open and whether that port is still
active for each IP address.

To refresh the information in the UPnP Portmap table, click the Refresh button.
