about confirming that the NIC and driver are properly installed.

Check the network

Inspect all cables and connections. Make sure that the cable

connection

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
