•
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.

"Internet" on page
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.
