distance from the Access Point. Therefore, a client that is close to an Access Point will
operate at a higher data rate than a client that is farther away from the Access Point.
The LAN-Express 802.11 Wireless Adapter includes two integral omni-directional
antennas. Note that the coverage footprint of the card’s antennas will vary depending on
the laptop’s design and the location of the CardBus slot in the computer. Two antennas are
provided to support antenna diversity, a technique which can improve system reliability.
Due to the characteristics of radio waves, it is possible that one antenna may provide
better performance than a second antenna installed a short distance away.
Proper antenna placement can help improve range. Here are some guidelines:
Try to keep the card’s antennas free of obstructions (particularly metal objects) and do not
place a sheet of metal (like a filing cabinet) between the antennas of two 802.11 devices.
Use the Wireless Client Utility to evaluate the signal strength and link quality between
802.11 devices.
Refer to the documentation that came with your Access Points for suggestions on how to
locate the AP and its antennas to maximize range and performance.
5-4 LED Indicators
The LAN-Express 802.11 Wireless Adapter includes two round, green LED indicators on
the end of the card. One is for power on/off status, and the other is for activity status.
These LEDs display the following behavior:
1.
Both LEDs are off when the card is not receiving power or when the driver is not
installed.
2.
The LEDs blink in an alternating pattern to indicate that the card is searching for an
