. 
The UPnP screen displays. 
5. 
Select the 
Turn UPnP On
check box.
By default, this check box is selected. UPnP for automatic device configuration can be 
enabled or disabled. 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. 
Type 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 receive 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. 
Type 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.
