Appendix B: Troubleshooting Tips
Problem: I cannot access my Internet service or send or receive email.
Solution:
The following front panel lights on the cable modem/router –
ONLINE
,
US
(upstream),
DS
(downstream), and
POWER –
must be solidly lit before your modem
will let you connect to the Internet. If they are not:
¾
Check all modem connections (power, Ethernet, and cable modem line).
¾
Unplug your cable modem/router and then plug it back in.
¾
Restart your computer.
¾
Check to see that your cable TV is working.
¾
Check with your cable service provider to make sure that high speed access is
available and running.
¾
In rare instances, the cable signal may be weak or noisy. If this is the case, call your
cable service provider.
¾
If you are using your PC’s Ethernet port, check that this port is functioning
correctly. If you are using wireless, check that your wireless connection is
functioning correctly. Refer to its documentation if necessary.
¾
Check that your Web browser is configured correctly. It should be set to use a
network connection; this might be called a LAN (Local Area Network) or
broadband connection.
¾
Check that your computer’s network settings are configured correctly. A Windows
computer should have a local area connection that should normally be Internet
Protocol version 4, Internet Protocol version 6, or TCP/IP; not AOL, Dial-up, or
Adapter. A Macintosh computer should be configured for Built-in Ethernet, and
TCP/IP should be set to Using DHCP.
