■
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.
■
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.
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.
