Modem Problems
If the modem seems slow
•
Check for excess static or noise on the line, which reduces the overall transmission speed. If
necessary, contact your telephone company about fixing this type of problem.
•
If you’re dialing internationally, line noise is often difficult or impossible to eliminate.
•
If you have call-waiting, disable it—see Windows Help and Support, and contact your telephone
company for information.
•
Eliminate extra connections in the line. If possible, connect directly to the wall jack.
•
Try another telephone line, preferably one normally used for a fax machine or modem.
If the modem doesn’t dial or no dial tone is detected
•
Check all cables and connections.
•
Connect a standard telephone to the phone line and make sure the line is working.
•
Make sure someone else isn’t using the same phone line.
•
Try another telephone line, preferably one normally used for a fax machine or modem.
•
If you’re in a foreign country/region, the dial tone may not be recognized by the modem. Click
Start, Control Panel, Printers and Other Hardware, Phone and Modem Options. Select your
modem on the Modems tab, then click Properties, Modem, and disable the option that waits for a
dial tone.
