If you cannot access the Internet from the PC, check the following:
◆ Make sure the WCM software and driver is correctly installed on your
system. If necessary, try uninstalling and reinstalling the software.
◆ If you cannot access the Internet, be sure your Windows system is
correctly configured for TCP/IP. The IP settings should be set to “obtain
an IP address automatically.”
◆ You may have moved out of the service area of the WiMAX network.
The WCM main screen should indicate that there is no connection. Call
the service provider for service coverage information.
◆ The service provider’s profile may not be configured correctly. Check
that the Authentication Mode settings are correct.
