Resolving Specific Issues 
LEDs Not Lit 
•  pwr 
If the pwr (power) LED is not lit, it is not connecting to the power source. Verify that the power cord 
is firmly plugged into the back panel of the router and that the other end is plugged into an active AC 
wall or power-strip outlet. 
•  dsl 
If the DSL LED is not lit, it is not detecting a valid signal from the Central Office (CO). Verify that 
the DSL cable is plugged into the correct router port and the router power cord is plugged into the 
electrical outlet. If the cables are secure, you should contact your Service Provider. 
•  enet LED Not Lit 
This indicates that there is no Ethernet link detected. If you are using the Ethernet connection method, 
check the Ethernet cable connection from the computer to the router. If you have used the wrong 
cable, the LED on the Ethernet (NIC) card in your computer will not be lit either. 
•  USB LED Not Lit 
This indicates that there is no USB link detected. If you are using the USB installation method, check 
the USB cable connection from the computer to the router. 
Login Password Error 
If after being prompted for the login password, you receive the error message: Login Password is 
invalid: 
• 
Retype the password, and then click Save Settings.  
•  If you forget your password, you must reset the router. 
Note  The password is case-sensitive. Be sure that you have not accidentally activated the Caps key.
