CHAPTER 9: Troubleshooting
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 convertible notebook has a v.90 modem, the
speed at which you can upload (send) data is limited to
33.6K. If your convertible 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.
Current fax technology only supports a maximum send
and receive rate of 14,400 bps.
Make sure that the line connected to the modem is
working and plugged into the appropriate port on your
convertible notebook. For the location of your modem
jack, see "Back" on page
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 a different modem cable. Some telephone cables do
not meet required cable standards and may cause
problems with the modem connection.
Shut down and restart your convertible notebook.
Run Windows modem diagnostics.
To run modem diagnostics:
a
Close all open programs.
b
Click or tap Start, then click or tap Control Panel.
The Control Panel window opens. If your Control
Panel is in Category View, click or tap Printers and
Other Hardware.
c
Click/double-click or tap/double-tap the Phone and
Modem Options icon, then click or tap the Modems
tab.
