Efficient Networks 5100 Series Basic Troubleshooting Steps, Interpreting the LED Display

SpeedStream Router User Guide

8: Troubleshooting

Connection problems usually occur when the router’s software configuration contains incomplete or incorrect information. The router’s diagnostic tools can help you identify and solve many of these problems.

Basic Troubleshooting Steps

Before contacting Technical Support, you should attempt to resolve the issue by following these steps:

1.Check the LEDs on the front panel to diagnose the possible problem.

2.Check specific issues addressed in this chapter, and follow the instructions for resolving the problem.

3.Reboot the router. Any settings you have configured will be saved.

4.Reset the router only as a last resort. You will lose any settings you have configured.

Interpreting the LED Display

The LED indicators on the front of the router give you a visual clue to the router activity. When the router is configured and working correctly, all LED indicator lights briefly turn a solid green. The following table shows the possible states indicated by the LEDs. If the LEDs indicate a problem, refer to “Resolving Specific Issues” later in this chapter.
