Section 3F: Troubleshooting Tips (Windows) 93
Problems, Causes, and Solutions
When properly installed, the SprintMobile Broadband USB modem is a highly
reliable product.
Most problems are caused by one of these issues:
䢇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).
䢇The drivers were not properly installed because of a problem with your
computer’s USB slot.
䢇System resources required by the USB modem are being used by other devices.
Tips when troubleshooting problems with your USB modem and software:
䢇Ensure your USB modem is inserted, not locked (page56), and not powered off
(page 40).
䢇Ensure the PWR LED is green.
䢇To determine the connection status, use the icons in the system tray (page42),
and icons in the Mobile Broadband window (page34) and GPS Receiver window
(page 36), and messages in the Mobile Broadband window (page38) and GPS
Receiver window (page 41).
䢇The alert log might indicate the nature of the problem (page76).
䢇Run diagnostic tools supplied with SprintConnection Manager (page 77).
䢇Check the Frequently Asked Questions (Windows) (page81).
䢇Use the resources listed in “Getting Help” (page12).
䢇If Sprint Connection Manager stopped working after you’ve upgraded to a
different version of Windows, see “SprintConnection Manager Stops Working
After UpgradingWindows” on page 97.
