I
Check for specific hardware problems, such as broken traces
or loose or broken solder connections. See Installing and
Connecting the NIC on page 34.
Make sure that the NIC software is installed correctly in the
I
computer. See Verifying Successful Installation on page 48.
Inspect all cables and connections. Make sure that the
I
cable complies with length and rating specifications
described in Installing and Connecting the NIC on page 34.
Examine the cable for obvious signs of damage, wear, or
I
crimping. Substitute a known working cable. Check the
length and rating of the cable. Make sure that the cable
complies with 10BASE-T or 100BASE-TX recommendations.
Make sure that you are running the latest BIOS for your
I
computer. If the BIOS has not been upgraded in the previous
12 months, contact the computer manufacturer to obtain
the current version of the BIOS software.
Run the NIC and Network Tests, as described in Running NIC
Diagnostics on page 143.
If the tests fail, replace the NIC with a known working NIC and
run the tests again, using the same configuration settings as
those used on the failed NIC. If the working NIC passes all
tests, the original NIC is probably defective. For information on
product repair, see Technical Support on page 171.
