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.
•
Review the troubleshooting information under
“Internet” on page 103 .
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 notebook has a v.90 modem, the speed at which you
can upload (send) data is limited to 33.6K. If your notebook
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 when you have a 56K modem
Current fax technology only supports a maximum send and
receive rate of 14,400 bps.
