Network Card Installation Problems
If your computer cannot find the EZ Card or the network driver
does not install correctly, check the following items.
• Make sure the card is securely seated in the PCI slot. Check
for any hardware problems, such as physical damage to the
card's edge connector.
• Try the card in another PCI busmaster slot. If all fails, test
with another EZ Card that is known to operate correctly.
• Check for resource conflict in the PCI configuration. Refer to
the section "PCI Compatibility" in this chapter.
• If there are other network cards in the computer, they may be
causing conflict. Remove all other cards from the computer
and test the EZ Card separately.
• Check for a defective computer or PCI bus by trying the
network card in another computer that is known to operate
correctly.
• Make sure your computer is using the latest BIOS available.
Network Connection Problems
There may be a network connection problem if the Link LED on
the card's bracket does not light, or if you cannot access any
network resources from the computer. Check the following items.
• Make sure the cable is within IEEE 802.3 Ethernet, or
IEEE802.3u Fast Ethernet standards for the type of network
you are using. Also, make sure cable lengths are within the
requirements specified in "Cables" on page 30.
• Inspect all network cables and connections. Make sure the
network cable is securely attached to the card's connector.
• Make sure the correct network card driver is installed for your
operating system. If necessary, try reinstalling the driver.
• Make sure the computer and other network devices are
receiving power. If you suspect a power outlet to be faulty,
plug another device into it to verify that it is working.

• If the the network card's speed or duplex mode has been
configured manually, check that it matches that of the
attached network device port. Note that it is recommended to
set the card to auto-negotiation when installing the network
driver.
• The port on the network device that the card is attached to
may be defective. Try using another port on the device.
• If you cannot access a Windows service on the network, check
that you have enabled and configured the service correctly. If
you cannot connect to a particular server, be sure that you
have access rights and a valid ID and password.
• If you cannot access the Internet, be sure you have
configured your system for TCP/IP.
