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 computer has a v.90 modem, the speed at which
you can upload (send) data is limited to 33.6K. If your
computer 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.
The modem is not recognized by your
computer
• Make sure that the line connected to the modem
is working and plugged into the appropriate port
on your computer. See your setup poster to make
sure that the connections have been made
correctly.
• If the modem shares the telephone line with
another device, make sure that the telephone
line is not in use (for example, someone is on the
telephone, or another modem is in use).
• Use the modem cable that came with your
computer. Some telephone cables do not meet
cable standards and may cause problems with the
connection.
• Shut down and restart your computer.
• Run Windows modem diagnostics.
To run modem diagnostics:
1 Close all open programs.
2 Click Start, then click Control Panel.
The Control Panel window opens. If
your Control Panel is in Category
View, click Printers and Other
Hardware.
3 Click the Phone and Modem Options
icon, then click the Modems tab.
