Troubleshooting
For additional configuration information for the LAN+Modem card under
Windows NT, see the file NTConfig.txt. This file also contains recommendations
for configuring specific computer models.
Symptom
Solution
Basic troubleshooting, applicable for all
problem situations.
Inspect all cables and connections.
Check whether your card is fully inserted into the slot.
Check the Web site for your computer to verify whether you have the latest
BIOS for your system. If not, download the newest BIOS version and follow the
upgrade instructions.
If you are not using the Softex PC Card Controller, reinstall your Service Pack
software after installing drivers for the LAN+Modem card.
The event log lists any problems found during system operation. To check the
event log for errors, select Programs/Administrator Tools/Event Viewer from the
Start menu.
Computer not connecting to network.
The most common problems under NT 4.0 occur because system resources are
not set correctly. If you are installing the LAN+Modem card using the
point-enabler procedure, refer to the file
NTConfig.txt
.
Remember that you can always use the Windows NT Diagnostics Resource tab
to determine which resources are free.
Driver not loading correctly.
Service Pack 3 or a later version should be installed before you install the Softex
PC Card Controller. If you are using Softex without any Service Pack software,
complete the following procedure:
1 Remove the card.
2 Uninstall the Softex software.
3 Install the Service Pack software. You can download the latest Service Pack
from Microsoft.
4 Reinstall the Softex software.
5 Reinstall the card.
Application cannot find the modem.
An older application may not be aware of COM ports higher than COM4. If your
modem is installed on COM5 or higher, reinstall the modem using one of the
legacy COM ports (COM2, COM3, or COM4). See the file
NTConfig.txt
for
more information.
Modem will not fax.
Most Windows fax software will not work with Windows NT. Contact Microsoft
for information about software for sending faxes.
Failure after Suspend/Resume.
This usually indicates a power-management problem. Since Windows NT 4.0
does not support power management, we recommend that you disable power
management in the BIOS. Make sure you have the latest BIOS for your computer
or upgrade your software from Microsoft.
Card not functioning.
Open Windows NT Diagnostics. From the Start menu, select
Programs/Admin Tools/Windows NT Diagnostics.
Windows NT Diagnostics lets you see where the drivers are loading in I/O, IRQ,
MEM ranges.
Check for resource conflicts and make sure the settings for the LAN+Modem
card are valid.
Modem driver does not load properly
If your modem did not install correctly, make sure you installed the driver from
the LAN+Modem card Installation CD. If not, remove and reinstall the driver
using the LAN+Modem card Installation CD.
