Troubleshooting Windows 98 Installations
Inspect all cables and connections.
Check whether your card is fully inserted into the slot.
Verify that you have the latest BIOS for your system. If
not, check the Web site for your computer and follow the
BIOS upgrade instructions.
Check for multiple installations of the card.
Check whether your system's PCMCIA or CardBus
Controller is installed and running properly: go to
Control Panel/System/Device Manager/PCMCIA Card.
Verify that the controller is present and shows no errors.
Open Control Panel/PC Card to confirm that the system
recognizes your card.
In Control Panel/Network make sure that you have the
correct clients and protocols installed.
Use Control Panel/System/Device Manager to inspect the
status of your LAN card.
If you see a red "X", enable the card by checking the
appropriate box under Properties.
If you see a yellow exclamation mark, click the icon to see
what the conflict is. Verify that there are adequate system
resources. Try to free system resources (for example, disable
the infrared port), then remove and reinstall the card.
This can occur when using NetWare servers and IPX/SPX
protocol. It happens when the frame type is selected
automatically. A temporary solution is to reboot after
disconnecting and reconnecting the cable in NetWare
networks. The permanent solution is to use specific frame
types such as 802.2 or 802.3.
In most cases, the automatic settings work fine. However,
if you to need to force speed or duplex settings to match
those of an attached device:
1 Open Control Panel/Network
2 Double click the LAN card.
3 Click the Advanced tab.
4 Highlight Network Link Selection and choose the
correct speed.
