•Check that your PC has the IP address of your gateway listed as the default gateway. If the IP configuration of your PC is assigned by DHCP, this information will not be visible in your PC’s Network Control Panel. Verify that the IP address of the gateway is listed as the default gateway. See the link to the online document “Internet Networking and TCP/IP Addressing” in Appendix B.

•Check to see that the network address of your PC (the portion of the IP address specified by the netmask) is different from the network address of the remote device.

•Check that your Cable Link LED is on.

•If your ISP assigned a host name to your PC, enter that host name as the Account Name in the Basic Settings screen.

Wireless Performance and Gateway Location

The range of your wireless connection can vary significantly based on the physical placement of the gateway. The latency, data throughput performance, and notebook power consumption of wireless adapters also vary depending on your configuration choices.

For best results, place your gateway according to the following guidelines:

•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 PCs have line-of-sight access (even if through walls).

•Away from sources of interference, such as PCs, microwave ovens, and 2.4 GHz cordless phones.

•Away from large metal surfaces.

•Put the antenna in a vertical position to provide the best side-to-side coverage. Put the antenna in a horizontal position to provide the best up-and-down coverage.

•To reduce interference when using more than one access point, NETGEAR recommends using 5 channel spacing between adjacent access points (for example, use Channels 1 and 6, or 6 and 11).

The time it takes to establish a wireless connection can vary depending on both your security settings and the gateway location. WEP connections can take slightly longer to establish. Also, WEP encryption can consume more battery power on a notebook computer.
