Resolve Modem, Fax, and Internet Connection Problems

NOTICE: Connect the modem to an analog line only. Connecting your
modem to a nonanalog line, such as a digital or private branch exchange
(PBX) line, will damage the modem.
NOTE: If you can connect to your Internet service provider (ISP) and send or receive a
fax, your modem is functioning properly. If you are sure that your modem is working
properly and you still experience problems connecting to your ISP , contact the ISP
technical support department for assistance.
•
Ensure that you have touchtone telephone service.
•
If you have call-waiting service, disable call-waiting. Refer to your local telephone
directory or call your telephone service provider for information on temporarily
disabling call-waiting.
•
If you have voice mail service, you may hear an irregular dial tone when you have
messages. Contact your telephone service provider for information on restoring a
normal dial tone.
•
If you have any other telephone devices plugged into the line, such as answering
machines, dedicated fax machines, or line splitters, bypass them and plug the
modem cable directly into the telephone connector on the wall.
•
Reseat the cable connections.
•
Try a different cable. If you are using a cable that is 10 feet or more in length, try a
shorter one.
•
Disconnect the cable from the modem and plug it directly into a telephone.
Listen for a dial tone.
•
Line noise can cause low connection speeds. If you have persistent problems, try
connecting the modem to a different telephone connector. You may also wish to
contact your telephone company to report the problem.
If you still have problems with a Dell-provided modem, call Dell for technical assis-
tance. For instructions, see Chapter 5, "Getting Help." If you have problems with a
non-Dell-provided modem, call the modem manufacturer.
