Chapter 3 Wireless Network Performance
This chapter explains how to use your RangeMax Dual Band Wireless-N USB Adapter 
WNDA3100 to connect to your wireless local area network (WLAN) and how to set up wireless 
security for the wireless USB adapter 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 losing connectivity. This also means that 
devices that are farther away mighty 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 two feet from large metal fixtures such as file cabinets, 
refrigerators, pipes, metal ceilings, reinforced concrete, and metal partitions.
Keep the 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:
