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:
䢇 Network coverage is not available (because of your “Network Mode” settings
[page 63], 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 device are being used by other devices.
Tips when troubleshooting problems with your Sprint Mobile Broadband USB
modem and software:
䢇 Ensure your device is inserted, not locked (page 51), and not powered off
(page 38).
䢇 Ensure the PWR LED is green.
䢇 To determine the connection status, use the icons in the system tray (page 39),
and icons and messages in Sprint Connection Manager (page 33 and page 35).
䢇 The alert log might indicate the nature of the problem (page 71).
䢇 Run diagnostic tools supplied with Sprint Connection Manager (page 72).
䢇 Check the Frequently Asked Questions (page 76).
䢇 Use the resources listed in “Getting Help” (page 27).
䢇 Has Sprint Connection Manager stopped working after you’ve upgraded to a
different version of Windows (page 85)?
