To configure port triggering, you need to know which inbound ports the application needs. Also, 
you need to know the number of the outbound port that will trigger the opening of the inbound 
ports. You can usually determine this information by contacting the publisher of the application or 
user groups or newsgroups.
To set up port triggering: 
1.Select Port Forwarding/Port Triggering under Advanced in the main...

has terminated.

•Advertisement Period. The advertisement period is 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 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...

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,...

Changing the MTU Size
The Maximum Transmission Unit (MTU) is the largest data packet a network device transmits. 
When one network device communicates across the Internet with another, the data packets travel 
through many devices along the way. If any device in the data path has a lower MTU setting than 
the other devices, the data packets must be split or “fragmented” to accommodate the one with the 
smallest MTU....

If you suspect an MTU problem, a common solution is to change the MTU size to 1400. If you are 
willing to experiment, you can gradually reduce the MTU size from the maximum value of 1500 
until the problem goes away. Ta b l e 5 - 1 describes common MTU sizes and applications.
To change the MTU size:
1.In the main menu, under Advanced, select WA N  S e t u p. 
2.In the MTU Size field, enter a new size between 64 and...

• Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most modern 
networks. Like video, however, streaming audio is also sensitive to latency and packet loss, so 
a congested network or a noisy link can cause problems.
• Backing up computers over the network has become popular due to the availability of 
inexpensive mass storage. Ta b l e 5 - 2 shows the time to transfer 1 gigabyte (1 GB) of...
