54 Mbps Wireless Router WGR614v8 User Manual • Wired Ethernet. As gigabit-speed Ethernet ports (10/100/1000 Mbps) 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. 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. 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. • Backing up computers over the network has become popular due to the availability of inexpensive mass storage.

As gigabit-speed Ethernet ports (10/100/1000 Mbps) 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

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

•

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.
•
Backing up computers over the network has become popular due to the availability of
inexpensive mass storage.
