a two-way cable service is provided.
• Check that all cables are connected to the modem and PC. Verify

limits. Check the cable
connections
for possible defects. Replac e the defective cable if necessa ry.
• Verify that the modem and computer are powered on.
• If the power source has a switch, ensure that it is switched on.
• Check the power outlet by plugging in another device that is functioning prope rly.
• Check the power cord with another device.
• Power off the modem, wait for 20 seconds and then power back on.

• For USB connection:
- Check that the USB driver is correctly installed see “USB Installation for
Windows 98, Window 2000 and Windows Me” on page 6.
• For Ethernet connection:
If the Link LED on the network adapter’s bracket does not light, check the
following items..
- Check that your computer is properly conf igured for TCP/IP see “Ethernet
Installation for Windows” on page 6.
- Make sure the UTP cable type complies with IEEE 802.3 Ethernet, or IEEE
802.3u standards for the type of network you are using. Also, make sure
cable lengths are within the requirements specified. (See “Making a
Connection to the Ethernet Port” on page 7.)

is securely attached to the network adapter’s connector.
- Make sure the correct network card driver is installed for your operati ng
