diagnostic tests

Run the NIC and Network Tests, as described in this chapter. 

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 Appendix D.
