Troubleshooting the Network Connection

If you encounter problems with using the NIC or connecting to the network, check the

table below for troubleshooting tips.

NOTE: Before inserting or removing the NIC from the computer, turn the

computer power off and unplug the power cord.

Tip Description

Check the NIC

hardware 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. See “Installing and Connecting the NIC” on

page 3.

Check the NIC

software installation

Make sure that the NIC software is installed correctly in the computer.

See the appropriate chapter for your operating system for information

about confirming that the NIC and driver are properly installed.

Check the network

connection

• Inspect all cables and connections. Make sure that the cable

complies with length and rating specifications described in

“Preparing the NIC and the Computer” on page 2.

• Examine the cable for obvious signs of damage, wear, or crimping.

Substitute a known working cable. Check the length and rating of

the cable. Make sure that the cable complies with 10BASE-T,

100BASE-TX, or 100BASE-FX recommendations.

Check the computer BIOS Make sure that you are running the latest BIOS for your 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 the NIC

Diagnostics Tests” on page 62.

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 “Obtaining

Support for your Product” on page 75.

• 3Com Knowledgebase
