N150 Wireless Router User Manual
Note: The maximum wireless signal rate is derived from the IEEE
Standard 802.11 specifications. Actual data throughput will vary.
Network conditions and environmental factors, including volume of
network traffic, building materials and construction, and network
overhead, lower actual data throughput rate.
The Mode options are:
-Up to 54 Mbps - Legacy Mode with maximum speed of up to 54 Mbps for b/g
networks.
-Up to 72 Mbps - Neighbor Friendly Mode - Will not interfere with neighboring wireless
networks.
-Up to 150 Mbps - Performance Mode - Maximum Nx speeds up to 150 Mbps. Using
channel expansion to achieve the 150 Mbps data rate, the WNR1000v3h2 will use the
channel you selected as the primary channel and expand to the secondary channel
(primary channel +4 or –4) to achieve a 40 MHz frame-by-frame bandwidth. The
WNR1000v3h2 will detect channel usage and will disable frame-by-frame expansion
if the expansion would result in interference with the data transmission of other
access points or clients.
• Security Options. The selection of wireless security options can significantly affect your
network performance. The time it takes to establish a wireless connection can vary
depending on both your security settings and router placement.
WEP connections can take slightly longer to establish. Also, WEP, WPA-PSK, and
WPA2-PSK encryption can consume more battery power on a notebook computer, and
can cause significant performance degradation with a slow computer. Instructions for
configuring the security options can be found in Choosing Appropriate Wireless Security
on page 20. A full explanation of wireless security standards is available in the online
document that you can access from Wireless Networking Basics in Appendix B.

Configuring WEP Wireless Security
WEP Shared Key authentication and WEP data encryption can be defeated by a determined
eavesdropper using publicly available tools.
WEP offers the following options:
• Automatic. With the Automatic option, the router will try both Open System and Shared
Key authentication. Normally this setting is suitable. If it fails, select Open System or
Shared Key. You can also refer to your wireless adapter’s documentation to see what
method to use.
• Open System. With Open System authentication and 64 or 128 bit WEP data encryption,
the WNR1000v3h2 router does perform data encryption but does not perform any
