This section provides information on troubleshooting procedures.

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

• A component of the High-Rate Wireless LAN system is out of range, which prevents 

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. 

The starting point to troubleshooting problems with your High-Rate Wireless LAN 
PC Card is to look at the LED activity of the High-Rate Wireless LAN PC Card. The 
following table provides an overview of the various modes of operation and the associated 
LED activity. The table also includes a number of troubleshooting hints, if required, that 
may help you solve the problem.
