Fine-Tuning Your Network

5-16

•

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.

–

Avoid windows unless communicating between buildings.

–

Place wireless devices away from various electromagnetic noise sources, especially those 
in the 2400–2500 MHz frequency band. Common noise-creating sources are:

•

Computers and fax machines (no closer than 1 foot)

•

Copying machines, elevators, and cell phones (no closer than 6 feet)

•

Microwave ovens (no closer than 10 feet)

–

Use a scanning utility to determine what other wireless networks are operating nearby, and 
choose an unused channel.

–

Turn off SSID broadcast, and change the default SSID. Other nearby devices might 
automatically try to connect to your network several times a second, which can cause 
significant performance reduction. 

•

Use WMM to improve the performance of voice and video traffic over the wireless link.

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.
