3G Broadband Wireless Router MBR624GU User Manual
5-12 Advanced Configuration
v1.0, January 2009
• 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.
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.
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 station.
See “Point-to-Point Bridge Configuration”.
• 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 “Multi-Point
Bridge Configuration”.
• Repeater with wireless client association. Sends all traffic to the remote access point. See
“Repeater with Wireless Client Association”..
On the main menu, below the Advanced heading, select Wireless Settings, and then select the
WDS radio button.
Note: Unless you change the security configuration, the wireless bridging and repeating
feature uses the default security profile to send and receive traffic.
