NETGEAR RangeMax Dual Band Wireless-N USB Adapter WNDA3100 User Manual

v1.0, December 2007
To get the best performance, use newer adapters such as RangeMax adapters for your 
computers. A high-speed router might be compatible with older 802.11b and 802.11g adapters, 
but the use of these older wireless technologies in your network can result in lower throughput 
overall (typically less than 10 Mbps for 802.11b and less than 40 Mbps for 802.11g). In 
addition, many older wireless products do not support the latest security protocols, WPA and 
WPA2.
Powerline
For connecting rooms or floors that are blocked by obstructions or are distant vertically, 
consider networking over your building’s AC wiring. NETGEAR’s Powerline HD family of 
products delivers up to 200 Mbps to any outlet, while the older-generation XE family of 
products delivers 14 Mbps or 85 Mbps. Data transmissions are encrypted for security, and you 
can configure an individual network password to prevent neighbors from connecting.
The Powerline HD family of products can coexist on the same network with older-generation 
XE family products or HomePlug 1.0 products, but they are not interoperable with these 
older products.
Wired Ethernet
As Gigabit Ethernet ports become common on newer computers, wired Ethernet remains a 
good choice for speed, economy, and security. Gigabit Ethernet can extend up to 100 meters 
with twisted-pair wiring of CAT-5e or better. A wired connection is not susceptible to 
interference, and eavesdropping would require a physical connection to your network.
Assessing Your Speed Requirements
Because your Internet connection is likely to operate at a much lower speed than your local 
network, faster local networking technologies might not improve your Internet experience. 
However, many emerging home applications require high data rates. For example:
Streaming HD video requires 10 to 30 Mbps per stream. Because latency and packet loss can 
disrupt your video, plan to provide at least twice the capacity you need.
Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most modern 
networks. Like video, however, streaming audio is also sensitive to latency and packet loss, so 
a congested network or a noisy link can cause problems.
Note: Actual data throughput will vary. Network conditions and environmental factors, 
including volume of network traffic, building materials and construction, and 
network overhead, can lower actual data throughput rate.
