If your residential gateway does not perform as expected, the following tips may 
help. If you need further assistance, contact your service provider. 

 

Verify that the plug to your residential gateway AC power is properly inserted 
into an electrical outlet. 

 

Verify that your residential gateway AC power cord is not plugged into an 
electrical outlet that is controlled by a wall switch. If a wall switch controls the 
electrical outlet, make sure the switch is in the ON position. 

 

Verify that the ONLINE LED status indicator on the front panel of your 
residential gateway is illuminated. 

 

Verify that your cable service is active and that it supports two-way service. 

 

Verify that all cables are properly connected, and that you are using the correct 
cables. 

 

If you are using the Ethernet connection, verify that your TCP/IP is properly 
installed and configured. 

 

Verify that you have called your service provider and given them the serial 
number and MAC address of your residential gateway. 

 

If you are using a cable signal splitter so that you can connect the residential 
gateway to other devices, remove the splitter and reconnect the cables so that the 
residential gateway is connected directly to the cable input. If the residential 
gateway now functions properly, the cable signal splitter may be defective and 
may need to be replaced. 

 

If you are connected to your PC with an Ethernet connection, your PC should be 
equipped with a Gigabit Ethernet card for best performance.
