Problem Solving

When diagnosing a problem with the router, note that the problem is often 
indicated by the states of the router’s LEDs. Table A-3 lists the states of the 
LEDs for various error conditions that can occur during initial installation of 
the device, along with probable causes and corrective actions to take.

All LEDs are 
off.

The router does not 
have power.

Secure the power cables at the 
back cover and between the 
power supply and wall outlet.

Check the wall outlet using 
another appliance or light, or 
plug the power cord into 
another outlet. If no power is 
available, check the wall 
outlet’s circuit breaker.

Replace the power supply or 
the router if the problem 
persists.
