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 for 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. The time to live for the advertisement is measured in 

hops (steps) for each UPnP packet sent. A hop is the number of steps allowed to 
propagate for each UPnP advertisement before it disappears. 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, then it might be necessary 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.

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. 

Wireless Bridging and Repeating

You can build large bridged wireless networks by using the router to configure a wireless 
distribution system (WDS). Some examples of wireless bridged configurations are:

Point-to-Point bridge. The router communicates with another bridge-mode wireless 

Multi-Point bridge. The router is the “master” for a group of bridge-mode wireless 

stations. Then all traffic is sent to this “master,” rather than to other access points. See 

.

Repeater with wireless client association. Sends all traffic to the remote access point. 

See 

Unless you change the security configuration, the wireless bridging 

and repeating feature uses the default security profile to send and 
receive traffic.
