Common Problems and Solutions

1.I cannot access my e-mail or Internet service.

Go through this checklist until your problem is solved:

•Make sure all of your connections are secure.

1.The Ethernet cable should be inserted completely into both the computer’s network adapter and the Ethernet port on the back panel of the Cable Modem.

2.If you are using the Cable Modem’s USB port, check the USB connections to the Cable Modem and your PC.

3.Check all cables between your computer and the Cable Modem for frays, breaks, or exposed wiring.

4.Make sure your power adapter is properly plugged into both the Cable Modem and the electrical outlet or surge protector. If the Cable Modem is properly connected, the Power and Cable LEDs on the Cable Modem should be solidly lit. The Activity LED should be solid or flashing.

•Press the Reset button on the back panel of the Cable Modem. Using an object with a small tip, such as a pen, push the button until you feel it click. Then try reconnecting to the Internet.

•Call your cable ISP to verify that their service is two-way. This Cable Modem is designed for use with two- way cable networks.

•If you installed the Cable Modem using the Ethernet port, make sure the computer’s network adapter is operating correctly. Make sure the adapter is listed in the Windows Device Manager and has no conflicts. For more information, refer to Windows Help.

•Make sure TCP/IP is the default protocol used by your computer. For more information, refer to “Appendix

B:Windows Help.”

•If you are using a cable line splitter so you can connect the Cable Modem and a television at the same time, remove the splitter and reconnect your cables so that the Cable Modem is connected directly to the cable wall jack. Then try reconnecting to the Internet.

2.The Online LED never stops flashing.

Go through this checklist until your problem is solved:

•Make sure the Cable Modem’s MAC address has been registered with your cable ISP. In order for the Cable Modem to work, you must call and have the ISP activate the Cable Modem by registering its MAC address. You can find the MAC address on a label located on the Cable Modem’s bottom panel.

•Make sure the coaxial cable is firmly attached between the Cable Modem and the wall jack.
