If the Link LED on the SMCWPCI-G does not light, or if you 
cannot access network resources from the computer, check the 
following:

Make sure the correct software driver is installed for your 
operating system. If necessary, try reinstalling the driver.

Make sure the computer and other network devices are 
receiving power.

The access point you want to attach to may be defective. Try 
using another access point.

If you cannot access a Windows service on the network, 
check that you have enabled and configured the service 
correctly. If you cannot connect to a particular server, be sure 
that you have access rights and a valid ID and password.

If you cannot access the Internet, be sure you have configured 
your system for TCP/IP.

If your wireless station cannot communicate with a computer in 
the Ethernet LAN when configured for Infrastructure mode, check 
the following:

Make sure the access point that the station is associated with 
is powered on.

If you still cannot connect, change the access point and all the 
stations within the BSS to another radio channel.

Make sure the SSID is the same as that used by the BSS 
configured on the access point, or the same as that used by 
the access points in the extended service set (ESS).
