Common Troubleshooting Issues 

This section describes common problems and offers solutions. 

 

I don't understand the front panel status indicators 

See 

Operation  of Front Panel  Indicators

  (on page 37), for more detailed information 

on front panel LED status indicator  operation  and function. 

 

The Residential Gateway does not register an Ethernet connection 

Try one of the following solutions: 

 

Verify  that your computer has an Ethernet  card and that the Ethernet  driver 

software is properly  installed. If you purchase and install an Ethernet  card, 

follow the installation instructions very carefully. 

 

Verify the status of the front panel status indicator lights. 

 

The Residential Gateway does not register an Ethernet connection after 

connecting to a hub 

If you are connecting  multiple PCs to the Residential  Gateway,  you should first 
connect the Residential Gateway to the uplink port of the hub using the correct 

crossover cable. The LINK LED of the hub will illuminate continuously. 

 

The Residential Gateway does not register a cable connection 

The Residential  Gateway  works with a standard, 75-ohm, RF coaxial cable. If you are 
using a different cable, your Residential Gateway will not function properly. Contact 

your service provider to determine whether  you are using the correct cable. 

 

There is no dial tone when I lift the handset 

 

Try the following solutions if you cannot hear a dial tone: 

 

Your telephone  wiring  may be connected  to the wrong  RJ-11 port on  the 
Residential Gateway. The Residential Gateway has two telephone  ports. Verify 

that you are connected  to the correct telephone  port. 

 

There  may be a problem  with your telephone  set. Use a different telephone  set 
and listen  to hear  dial tone.
