Chapter 6: 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 jack are secure.
You can also call your telephone service and have your telephone line
checked for noise or low line levels.
■ Try another telephone line (either a different telephone number in your
business or a telephone line at a different location). If you can connect
on this line, call your telephone service.
■ Try connecting with the modem at a lower connection speed. If reducing
the connection speed lets you connect, contact 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 technical
support for help.
■ Try a different communications program. The problem may be with just
one program.
Your 56K modem does not connect at 56K
Current FCC regulations restrict actual data transfer rates over public telephone
lines to 53K. Other factors, such as line noise, telephone service provider
equipment, or ISP limitations, may lower the speed even further.
If your system has a v.90 modem, the speed at which you can upload (send)
data is limited to 33.6K. If your system has a v.92 modem, the speed at which
you can upload data is limited to 48K. Your ISP may not support 48K uploads.
Your fax communications program only sends and receives faxes at
14,400 bps even though you have a 56K modem
Current fax technology only supports a maximum send and receive rate of
14,400 bps.
The modem is not recognized by your server
■ Make sure that the line connected to the modem is working and plugged
into the correct jack on the modem.
