•
Disconnect any answering machine, fax machine,
or printer that is on the same line as the modem.
Do not connect these devices to the same
telephone line as the modem.
•
Make sure that you are not using a digital,
rollover, or PBX line. These lines do not work
with your modem.
•
Check for line noise (scratchy, crackling, or
popping sounds). Line noise is a common
problem that can cause the modem to connect
at a slower rate, abort downloads, or even
disconnect. The faster the modem, the less line
noise it can tolerate and still work correctly.
Listen to the line using your telephone. Dial a
single number (such as 1). When the dial tone
stops, listen for line noise. Wiggle the modem
cable to see if that makes a difference. Make sure
that the connectors are free from corrosion and
all screws in the wall or telephone wall jack are
secure.
You can also call your telephone service and have
the telephone line checked for noise or low line
levels.
•
Try another telephone line (either a different
telephone number in your house or a telephone
line at a different location). If you can connect
on this line, call your telephone service to fix the
original line.
•
Try connecting with the modem at a lower
connection speed. If reducing the connect speed
lets you connect, call your telephone service. The
telephone line may be too noisy.
You cannot connect to the Internet
•
The ISP may be having technical difficulties.
Contact your ISP for technical support.
•
See if the modem works with a different
communications program. The problem may be
with just one program.
