4. Issues and Resolutions

This section identifies known problems with LAN+Modem card 
installation and operation. Topics include:

A. General Issues
B. Windows 2000
C. Windows Millennium Edition (Me)
D. Windows 98
E. Windows 95 OSR 2
F. Windows NT 4.0
G. Specific Hardware Platforms

------------------------------------------------------------
A. General Issues
------------------------------------------------------------
1. You Receive the Message "Digital Signature Not Found"

During installation you may receive a "Digital Signature 
Not Found" message. Click "Yes" to continue the installation.

------------------------------------------------------------
2. Your Modem Won't Answer a Fax Call

Most communications software packages allow you to select 
one of the following ways to answer a call:  "detect fax & 
data", "data only", "fax only", and "ignore ring".  If you 
have "detect fax & data" selected and your modem won't 
answer fax calls, set the answer mode to "fax only".

------------------------------------------------------------
3. System Hangs When Card is in Docking Station

Some laptop docking stations do not properly manage 
resources for the LAN+Modem card. Install the LAN+Modem
card only in the computer's main card slots.

------------------------------------------------------------
4. Network Performance is Slow or Computer Not Connecting
   to Network.

If the network interface is set to autosense with auto
polarity disabled and the cable is connected to a port set
for 10Mbps/Full, performance may be affected. If switch is
configured for 10Mbps/Full and the card for Auto, a 
mismatch of duplex mode may result.

If you are connecting to a dual-speed 10/100 hub or to a
switch forced to 10Mbps speed, make sure the settings on the
card match those on the switch.

If not, disable autopolarity and set the speed and duplex
to match the port.

To disable autopolarity:

          1. Open Control Panel/Network.
          2. Click Adapters. 
          3. Select Properties and disable Auto Polarity.
          4. Reboot

You can manually set network speed and polarity for all 
supported environments.

------------------------------------------------------------
5. Unable to Ping Between Two Installed LAN Cards

This could be a problem with how the IP addresses are bound.
Bind one card to a static IP address and set the other to 
to specify the IP address automatically.

------------------------------------------------------------
6. Wake-Up-On-Ring Feature Enabled; Card Will Not Wake Up

Suspend/Wakeup-On-Ring is not currently supported by Windows.
Hence, in suspend mode, your computer turns off the power to 
the card, which means that there is no way for it to detect 
the ring.

------------------------------------------------------------
7. System Refuses to Enter Suspend Mode While a 
   Communications Application is Running

The LAN+Modem card does not support forcing the system into
suspend mode while a communications application (such as
HyperTerminal) is running. Windows environments reject 
suspend-mode requests in such instances.

After the suspend-mode failure, the LAN interface may no
longer show up in the system as a valid device. If this
happens, try one of the following:

         - Close all programs and log in as a different
           user.

         - Remove the card from the computer, reinsert
           it in the same slot, and run Suspend/Resume
           again.

------------------------------------------------------------
8. The System Does not Recognize the Card, or Could Not 
   Install the Card 

The system could not find a valid .INF file. This is a 
BIOS problem. Contact your computer vendor for information
on obtaining and installing the latest BIOS version for your
computer.

------------------------------------------------------------
B. Windows 2000

When installing the card, the path for Windows 98 is 
d:\install\disks\win9x\drivers (where d: is the CD-ROM 
drive).

------------------------------------------------------------
2. Card Won't Install

This problem has been observed on several hardware platforms
and usually indicates that the computer's BIOS is not 
properly supporting Windows 98. Upgrade to a current BIOS
that supports Windows 98. Contact your computer manufacturer
for details.

------------------------------------------------------------   
3. Problems With IntraNetware Client 2.2

Novell IntraNetware client version 2.2 does not support 
Windows 98. If you try the LAN+Modem card with this network
operating system, you may experience problems. Install 
Novell IntraNetware client version 3.1 or later.

------------------------------------------------------------
4. Cannot Install Two Winmodems

This is a Winmodem limitation. Only one installed modem
will function under Windows 98. However, both LAN interfaces 
should behave normally.

If you must have two modems installed, you can run a 
controller-based modem simultaneously with a Winmodem.

------------------------------------------------------------
5. Modem Does Not Give Sound

With the default audio settings for Windows 98, you may not
hear the sound from the modem when you dial out. To enable 
the sound, complete the following procedure:

      1. Locate the speaker icon in the system tray.

         If there is no speaker icon in the system
         tray, open the Control Panel and double-click

computer's BIOS.

------------------------------------------------------------
E. Windows 95 (OSR 2)
------------------------------------------------------------

1. Drivers for Card Installation

When installing the card, the path for Windows 95 is 
d:\install\disks\win9x\drivers (where d: is the CD-ROM 
drive).

------------------------------------------------------------
2. An Option to Select NDIS 5 Appears in Windows 95 OSR 2 
   Driver Options

Although this prompt may appear under Windows 95, this 
operating system supports only NDIS 4.

------------------------------------------------------------
3. Modem Does Not Give Sound

With the default audio settings for Windows 95, you may not
hear the sound from the modem when you dial out. To enable
the sound, complete the following procedure:

      1. Locate the speaker icon in the system tray.

         If there is no speaker icon in the system
         tray, open the Control Panel and double-click
         Multimedia. On the Audio page, make sure
         Show volume control on the task bar is checked

      2. Double click the speaker icon in the system
         tray.

      3. When the Master Out window opens, select
         Options.

         box is checked. Click OK.

      5. When the Master Out window is redisplayed,
         check Mono In Balance. Ensure that the mute
         box is unchecked.

If the modem still does not make a sound, you may need to 
update your computer's BIOS.

------------------------------------------------------------
4. Can't Install Two LAN+Modem Cards

The modem driver supports only one modem in Windows 95 
environments. For this reason, dual installations are not 
supported. 

You can disable one modem installation and operate with one 
modem and two LAN connections. For technical information, 
see Microsoft Limitation Article Q184191 on the Microsoft
on-line support Web site.

------------------------------------------------------------
F. Windows NT 4.0
------------------------------------------------------------

1. Drivers for Card Installation

When installing the card using point enabler or System Soft,
the path is d:\install\disks\winnt40\standard (where d: is
the CD-ROM drive).

When using Softex, the path is 
d:\install\disks\winnt40\softex (where d: is the CD-ROM
drive).

------------------------------------------------------------
2. Installing the Modem Interface Using System Soft Software

         1. Insert the Installation CD in the CD-ROM Drive.
         2. From the Windows Start Menu select Run.
         3. Browse to d:\install\disks\winnt40\standard

         4. Select WMSETUP.EXE and Click OK to run the 
            program.
         5. In the setup window, select Install.
         6. When prompted, set your COM port and click OK.

------------------------------------------------------------
3. 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 following table for 
examples of what resources to select.

Remember that you can always use the Windows NT Diagnostics 
Resource tab to determine which resources are free.

         --------------------------------
         System           Recommended IRQ
         --------------------------------
         Micron Trek2           10
         Dell Latitude LT       10  
         Dell Inspiron 7000     10
         Dell Inspiron 3200     10,11

         --------------------------------

For a more detailed list of what resources to try for 
specific notebook computer models, use the User Guide's 
link to file NTconfig.txt.

------------------------------------------------------------
4. Suspend/Resume and Hot-Swap Problems

This class of NT problems may be due to limitations in the
support for dual-function cards under various card and 
socket services. Remove the card wizard or card and socket
services software and reinstall the card using the point
enabler installation procedure described in the User Guide.  

This problem may be fixed in later versions of the software.
Contact your software manufuacturer for information on 
updates.

------------------------------------------------------------
5. Card Slots Disabled in NT 4.0 After Card Installation

When attempting to install a 16-bit adapter, you must enable
the PC Card device in Windows NT 4.0. To do this, follow
these steps:

           1. Click My Computer/Control Panel/Devices. 
           2. Scroll down to PCMCIA. 
           3. Click Startup.  
           4. Change the selection to BOOT and click OK.  
           5. Restart the computer.

On some computers, you must to set the BIOS for CardBus 
support. Contact your computer manufacturer for the correct
procedure.

------------------------------------------------------------
6. Network Setup Wizard Busy or Not Responding 

This has been observed on some systems running SystemSoft
Card and Socket Services version 4.10.13.

The installation seems to proceed normally. At the message:
"Windows NT is now ready to start the Network so that you can
complete the installation of Networking. Click Next to start
the Network.", turn off the computer and restart it. This
will restore the card to normal operation.

------------------------------------------------------------
G. Specific Hardware Platforms
------------------------------------------------------------

1. Fujitsu Lifebook 585TX

   A. While using the LAN and modem functions at the same 
      time, the computer fails to respond.

Simultaneous LAN and modem operation is not supported on 
this computer.

------------------------------------------------------------
2. Texas Instruments Extensa 390

   A. System will not detect card.

The LAN+Modem card is not supported on this computer. 

------------------------------------------------------------
3. Toshiba (all models)

   A. Card does not respond when configured with default
      resources

This problems applies to systems running Service Pack 3 
under Windows NT 4.0. When the card is set up using the 
default settings, the system may not respond. Toshiba
systems require IRQ 11 for the LAN+Modem card. Changing the
interrupt from 10 to 11 solves the problem.

Refer to file NTconfig.txt, to which you can link from the 
user guide.

On the Toshiba Satellite 4000 CDT, IRQ 15 is already in
use (ATAPI). On this platform, use the Windows NT 
Diagnostics Resource tab to determine which resources are
free. You can, for example, create a COM8 at IO 3F8 with 
IRQ 13.
