Troubleshooting the LEDs
If you have difficulty using or installing your High-Rate Wireless LAN product, the error
may be due to various causes:

the PC Card from establishing a wireless connection with the network.
• There is a configuration mismatch, which prevents the PC Card from establishing a
wireless connection with the (correct) network.
• Absence of or conflict with the High-Rate Wireless LAN device driver.
• there is a problem or conflict with the PC Card slot, which prevents the PC Card from
receiving power.
• There is a conflict with the High-Rate Wireless LAN hardware and another device.
