6-2 Fine-Tuning Your Network
v1.1, May 2008
– 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.
– 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)
• Choose your settings.
– 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.
