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.
