Troubleshooting
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.
■ Review the troubleshooting information under “Internet” on
page 85 .
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.
