Modem Problems If the modem seems slow • Try another telephone line, preferably one normally used for a fax machine or modem. • Eliminate extra connections in the line. If possible, connect directly to the wall jack. • 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 can be difficult to eliminate.) • If you have call-waiting, disable it-see Windows Help and Support, and contact your telephone company for information. If the modem doesn't dial or no dial tone is detected • Make sure someone else isn't using the same phone line. • Check all cables and connections. • Connect a standard telephone to the phone line and make sure the line is working. • Try another telephone line, preferably one normally used for a fax machine or modem. • If you're in a foreign country, the dial tone may not be recognized by the modem. Click Start, Control Panel, Printers and Other Hardware, Phone and Modem Options.
