Modem Problems
If the modem seems slow
• Check for excess static or noise on a line 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 a problem that’s difficult or
impossible to eliminate.
• If you have call-waiting, disable it—your telephone company can provide
instructions. It can cause symptoms similar to static.
• 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.
