Troubleshooting
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
“Back” on page 10 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 required cable standards and may cause problems with the modem
connection.
■
Shut down and restart your computer.
■ Run Windows modem diagnostics.
To run modem diagnostics:
1

4
Click your modem, then click

. The Modem Properties dialog box opens.

Click the
Diagnostic

Query Modem
. If information about the modem
appears, the modem passed diagnostics. If no modem information is available, a
white screen appears with no data, or if you get an error such as
port already open
or the modem has failed to respond , the modem did not pass diagnostics.
The modem is noisy when it dials and connects
When your modem tries to connect to another modem, it begins handshaking .
Handshaking is a digital “getting acquainted” conversation between the two modems that
establishes connection speeds and communication protocols. You may hear unusual
handshaking sounds when the modems first connect. If the handshaking sounds are too
loud, you can turn down the modem volume.
