Tip Description
Check the NIC
installation Make sure that the NIC is installed correctly in a PCI slot. Check for specific
hardware problems, such as broken traces or loose or broken solder
connections.
Check the
network
connection Inspect all cables and connections. Make sure that the cable complies with
the cable requirements described under
Preparing the NIC and the
Computer on page 8 .
Check the
computer BIOS Make sure that you are running the latest BIOS for the 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
diagnostic tests Run the NIC and Network Tests, as described in Running NIC Diagnostics in
Windows on page 53 .
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
