NETGEAR Wireless-N Router WNR2000 User Manual • Channel. This field determines which operating frequency is used. It should not be necessary to change the wireless channel unless you notice interference problems with another nearby wireless network. The wireless router uses channel bonding technology to extend the bandwidth for data transmission. For more information about the wireless channel frequencies, see the online document that you can access from "Wireless Networking Basics" in Appendix B. • Mode. This field determines which data communications protocol is used. You can choose from: - Up To 54 Mbps. Legacy mode, for compatibility with the slower 802.11b and 802.11g wireless devices. - Up To 145 Mbps. Neighbor Friendly mode, for reduced interference with neighboring wireless networks. Provides two transmission streams with different data on the same channel at the same time, but also allows 802.11b and 802.11g wireless devices. This is the default mode. - Up To 300 Mbps. Performance mode, using channel expansion to achieve the 300 Mbps data rate. The WNR2000 router 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 WNR2000 router 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. 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. • 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 WPA2PSK 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 2-1. A full explanation of wireless security standards is available in the online document that you can access from "Wireless Networking Basics" in Appendix B. 3.
