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.

. 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 open and whether that port is still active for each IP address.

Optimizing Wireless Performance
The speed and operating distance or range of your wireless connection can vary significantly
based on the physical placement of the wireless router. You should choose a location for your
router that will maximize the network speed.
Note:
Failure to follow these guidelines can result in significant
performance degradation or inability to wirelessly connect to the
router. For complete range and performance specifications, click the

The following list describes how to optimize wireless router performance.
•
Identify critical wireless links.
If your network has several wireless devices, decide which wireless devices need the
highest data rate, and locate the router near them. Many wireless products have
automatic data-rate fallback, which allows increased distances without loss of
connectivity. This also means that devices that are farther away might be slower.
Therefore, the most critical links in your network are those where the traffic is high and
the distances are great. Optimize those first.
•
Choose placement carefully.
For best results, place your router:
-
Near the center of the area in which your computers will operate.
-
In an elevated location such as a high shelf where the wirelessly connected
computers have line-of-sight access (even if through walls).
-
Avoid obstacles to wireless signals.
-
Keep wireless devices at least 2 feet from large metal fixtures such as file cabinets,
refrigerators, pipes, metal ceilings, reinforced concrete, and metal partitions.
-
Keep away from large amounts of water such as fish tanks and water coolers.
•
Reduce interference.
-
Avoid windows unless communicating between buildings.
