Troubleshooting
Connection problems usually occur when the router’s software configuration contains incomplete
or incorrect information. Diagnostic tools are available to help identify and solve problems that
may occur with your router.
Using LEDs
STEP 1: Check the LEDs on the front panel
Certain hardware problems can be diagnosed and solved by checking the LEDs. After
powering on the router, all LED indicator lights turn a solid green.
If the Power (PWR) LED is off:
• Check that the power cord is firmly plugged into the back panel of the router
and the other end into an active AC wall or power-strip outlet.
• Check that the power switch is turned on.
The following table shows the possible states of the LEDs (lights) on the 5667 router/bridge.
