ProSafe Premium 3 x 3 Dual-Band Wireless-N Access Point WNDAP620
Note: Failure to follow these guidelines can result in significant
performance degradation or inability to connect wirelessly to the
wireless access point. For complete performance specifications, see
Appendix A, Supplemental Information.
Note: Before you position and mount the wireless access point at its
permanent position, first configure the wireless access point and test
the computers on your LAN for wireless connectivity as explained in
this chapter.
For best results, place your wireless access point according to the following general
guidelines:
•Near the center of the area in which the wireless devices will operate.
•In an elevated location such as a high shelf where the wirelessly connected devices have
line-of-sight access (even if through walls).
•Away from sources of interference, such as computers, microwaves ovens, and 2.4 GHz
cordless phones.
•Away from large metal surfaces or water.
•Placing an external antenna in a vertical position provides best side-to-side coverage.
Placing an external antenna in a horizontal position provides best up-and-down coverage.
(An external antenna does not come standard with the wireless access point.)
•If you are using multiple wireless access points, it is better if adjacent wireless access
points use different radio frequency channels to reduce interference. The recommended
channel spacing between adjacent wireless access points is five channels (for example,
use Channels 1 and 6, or 6 and 11, or 1 and 11).
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
encryption can consume more battery power on a notebook computer.
Ethernet Cabling Requirements
The wireless access point connects to your LAN using twisted-pair Category 5 Ethernet cable
with RJ-45 connectors.
LAN Configuration Requirements
For the initial configuration of your wireless access point, you need to connect a computer to
the wireless access point.
