Troubleshoot if you are able to connect to the Internet but not able to browse any Web pages with your Sprint 3G/4G USB Modem U300

Last Updated: Nov 18, 2013

Below are some potential resolutions on how to browse Web pages with your Sprint 3G/4G USB Modem U300:


The internet browser is incorrectly configured:

  1. Check the connection settings of your browser to ensure that no conflicting settings exist.
    • For Internet Explorer, click Tools > Internet Options and select the Connections tab. Ensure that either the option Never dial a connection is selected, or that the Sprint Connection is set as the default. Also ensure that no proxy information is specified by clicking on the Settings button and ensuring that the checkbox labeled Use a proxy server for this connection is unselected.
    • For Mozilla Firefox, click Tools > Options and select the General tab. Click the Connection Settings button and ensure that Direct connection to the Internet is selected.
    • For other browsers, consult the software manufacturer for assistance.

The firewall or Internet security application is interfering with the browsing.

Try to disable any applications that may be restricting your access to the Internet, such as Windows Firewall, or Anti-Virus software. If the problem is resolved by this action, contact the software manufacturer for assistance configuring the software to allow for the desired connection.


Disconnect all other Internet connections.

While using the Sprint SmartView software, disconnect all other Internet connections such as WiFi or local LAN connections before you access the Sprint 3G network.
