Observing Performance, Placement, and Range Guidelines

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

Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the router. For complete range and performance specifications, please see Appendix A, Technical Specifications.

For best results, place your firewall:

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 computers have line-of-sight access (even if through walls).
Away from sources of interference, such as computers, microwaves, and 2.4 GHz cordless phones.
Away from large metal surfaces.

The time it takes to establish a wireless connection can vary depending on both your security settings and 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.
