Tip
Description
Check the NIC installation
On a Windows 98, 95, or NT 4.0 PC, make sure that you have run the preinstallation program, as
described in "Running the Preinstallation Program for Windows 95/98" on page 10. This program must
be run
before
installing the NIC in a PC with one of these operating systems.
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 length and rating
specifications described in "Connecting the NIC to the Network" on page 14.
Check your PC BIOS
Make sure that you are running the latest BIOS for your PC. If your BIOS has not been upgraded in the
previous 12 months, consult your PC manufacturer to obtain the current version of your BIOS software.
Run the NIC diagnostic tests
Run the NIC and Network Tests, as described in “Running the NIC Diagnostics Tests” on page 47.
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” in Appendix E.
Run the 3Com Connection
Assistant self-service.
Install the 3Com Connection Assistant and run the self-service option. This option analyzes your NIC and
system, and guides you through troubleshooting steps to help resolve the problem.
