Wireless Network Performance
This chapter explains how to use your Wireless Express Card to connect to your wireless local area
network (WLAN) and how to set up wireless security for the Wireless Express Card so that it
matches the wireless security settings for your network.
Optimizing Wireless Performance
The speed and operating distance or range of your wireless connection can vary significantly based
on the location of the wireless router. You should choose a location for your router that will
maximize the network speed.
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 wireless devices 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)
