5-14 Fine-Tuning Your Network
v1.1, May 2008
• 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.
– 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.
Configuring Quality of Service
Quality of Service (QoS) is an advanced feature that can be used to prioritize some types of traffic
higher or lower than others. The Wireless-G Router can provide QoS prioritization over the
wireless link and on the Internet connection. To configure QoS, use the QoS Setup screen.
