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—your telephone company can provide
instructions.
• 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
