Network Connection Problems
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.
If you cannot resolve the problem, check the logs in the Debug Monitor (see “Card
Settings” on page 3-9) and contact your service provider.
