Troubleshooting

No LEDs are lit

modem

The cable modem has no power. Make sure that:
• The power adapter is correctly connected to the cable modem.
• The power adapter is correctly connected to a functioning power 

outlet. If it is to a power strip, make sure that the power strip is 
turned on.

• You are using the correct power adapter.

There is a hardware connection problem, or you do not have cable 
service. Do the following:
• Make sure that the cable connector is securely plugged in at the 

cable modem.

• Turn the power to the cable modem off and on.
• You might not have active cable service yet. Contact your provider to

There is a hardware connection problem. Do the following:
• Make sure that the cable connector is securely plugged in to the 

cable modem and the computer.

• If you are not using the cable included with the cable modem, check 

that the Ethernet cable is a straight-through patch cable.

You cannot 
connect to the 
Internet

It can take up to 15 minutes to establish a connection the first time you 
power on your cable modem. Always leave your cable modem plugged 
in to AC power and connected to the cable system. Do the following:
• Check your cable connections. Connectors should be finger tight.
• Make sure that you have powered up in the following sequence:

-  Turn on your cable modem first, and wait until the LEDs stop 

flashing.

-  If your computer is connected to the cable modem, turn on the 

computer.

• If you have a home network, check the TCP/IP configuration.

-  For Windows, the network properties should be set to obtain an IP 

address automatically.

-  For Macintosh computers, the TCP/IP (or Network) control panel 

should be set to Using DHCP Server.
