Problems, Causes, and Solutions

When properly installed, the Sprint Mobile Broadband USB modem 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 68], 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 USB slot.

⬤System resources required by the USB modem are being used by other devices.

Tips when troubleshooting problems with your USB modem and software:

⬤Ensure your USB modem is inserted, not locked (page 56), and not powered off (page 40).

⬤Ensure the PWR LED is green.

⬤To determine the connection status, use the icons in the system tray (page 42), and icons in the Mobile Broadband window (page 34) and GPS Receiver window (page 36), and messages in the Mobile Broadband window (page 38) and GPS Receiver window (page 41).

⬤The alert log might indicate the nature of the problem (page 76).

⬤Run diagnostic tools supplied with Sprint Connection Manager (page 77).

⬤Check the Frequently Asked Questions (Windows) (page 81).

⬤Use the resources listed in “Getting Help” (page 12).

⬤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 97.
