Problems, Causes, and Solutions
When properly installed, the Sprint Mobile Broadband card is a highly reliable product.
Most problems are caused by one of these issues:
⬤Network coverage is not available (because of your “Network Mode” settings [page 80], or because you are outside the network, or because of an account or network problem).
⬤The drivers were not properly installed because of a problem with your computer’s ExpressCard slot, PC Card slot, or with the ExpressCard to PC Card adapter.
⬤System resources required by the card are being used by other devices.
Tips when troubleshooting problems with your card and software:
⬤Ensure your card is inserted, not locked (page 68), and not powered off (page 52).
⬤If the data performance of your card is not optimal, ensure Auto Start GPS on connect (page 84) is not enabled.
⬤Check the status of the LEDs; to interpret their status, see “LED Operation” on page 136. If the LEDs are not lit, ensure that Device LED Enabled (page 82) is selected.
⬤To determine the connection status, use the icons in the system tray (page 54), and icons in the Mobile Broadband window (page 46) and GPS Receiver window (page 48), and messages in the Mobile Broadband window (page 50) and GPS Receiver window (page 53).
⬤The alert log might indicate the nature of the problem (page 88).
⬤Run diagnostic tools supplied with Sprint Connection Manager (page 89).
⬤Check the Frequently Asked Questions (Windows) (page 93).
⬤Use the resources listed in “Getting Help” (page 13).
⬤If Sprint Connection Manager stopped working after you’ve upgraded to a different version of Windows, see “Sprint Connection Manager Stops Working After Upgrading Windows” on page 107.
