CHAPTER 9: Troubleshooting

■
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.
