If you have call-waiting, disable it—your telephone company can provide
instructions.
If the modem dials but doesn’t connect
•
Make sure you’re using an analog telephone line. You must not use a digital line. In a
hotel, ask for a data line.
•
Try another telephone line, preferably one normally used for a fax machine or
modem.

The modem at the other end may have a problem. Try dialing to a different modem.

The host modem may not support a 56K (V.90) connection speed.

Connection speed depends on several factors, such as the condition of the telephone
line. Try connecting another time.
If the modem will not connect at any speed
•
Make sure you’re using an analog telephone line. You must not use a digital line. In a
hotel, ask for a data line.

Make sure the telephone line goes directly from the notebook’s modem phone jack to
the telephone jack on the wall.

using the line and that the phone is not off the hook.

Try another telephone line, preferably one normally used for a fax machine or
modem.

Contact your Internet Service Provider (ISP). It's possible that service may be
