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 63], 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 device are being used by other devices.
Tips when troubleshooting problems with your Sprint Mobile Broadband USB
modem and software:
Ensure your device is inserted, not locked (page 51), and not powered off
(page 38).
Ensure the PWR LED is green.
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).
The alert log might indicate the nature of the problem (page 71).
Run diagnostic tools supplied with Sprint Connection Manager (page 72).
Check the Frequently Asked Questions (page 76).
Use the resources listed in "Getting Help" (page 27).
Has Sprint Connection Manager stopped working after you've upgraded to a
different version of Windows (page 85)?
