NOTE: If your modem can dial and connect to one Internet service provider (ISP) or to
a fax machine, your modem is functioning properly. For assistance, contact the ISP to
which you cannot connect.
If you are experiencing problems with a modem, perform the following checks.
If you have any other telephone devices plugged into this line, such as answering
machines, dedicated fax machines, or line splitters, then bypass them and plug
the modem cable directly into the telephone connector on the wall.
Disconnect the cable from the modem and plug it directly into a telephone.
Listen for a dial tone.
Check that the modem cable is connected to the green line-in jack on the
modem. Reseat the cable connections.
Plug a telephone cable into the adjacent telephone jack on the modem and listen
for a dial tone.
Try a different cable; if you are using a cable that is 10 feet or more in length, try a
shorter one.
Low connection speeds can be caused by line noise. If you have persistent prob-
lems, contact your telephone company to check for data noise and imbalanced
lines.
Refer to “Modem” in Chapter 6 for further troubleshooting information.
