Problem

Solution

Power LED is Off

• Check connections between the ADSL Wireless Modem Router, the external

 

 

power supply, and the wall outlet.

 

 

• If the power indicator does not turn on when the power cord is plugged in, you

 

 

may have a problem with the power outlet, power cord, or external power supply.

 

 

However, if the unit powers off after running for a while, check for loose power

 

 

connections, power losses, or surges at the power outlet.
