Modem Problems

✎

See also the “Internet Problems” section.

No dial tone is audible

■ Verify that the modem cable is securely connected to the telephone

wall jack and to the RJ-11 jack on the notebook or port replicator.

■ Verify that the telephone wall jack is functional by plugging a

telephone into the wall jack. If you do not hear a dial tone on

the telephone, connect the modem to another wall jack or contact

your telephone service provider.

■ Verify that no other modem or telephone is using the telephone line.

(An extension telephone that has not been hung up may be causing

the problem.)

■ Verify that the correct dialing mode (tone or pulse) is selected.

■ Verify that the modem is connected to an analog, not a digital,

telephone line. A line described as a PBX line is usually a digital line.

A telephone line described as a data line, fax machine line, modem

line, or standard telephone line is probably an analog line.

■ If you are not in your home country, refer to the section of your

notebook documentation that provides instructions for using the

modem internationally. The instructions may be in your

model-specific documentation or in a Modem and Networking guide.

Modem does not dial correctly

■ Verify that you are dialing the correct number.

■ Dial the number with a telephone. If you hear a busy signal, dial the

number with the modem at a later time.
