Troubleshooting Your System
Remove and reinstall the drivers if applicable. See the NIC's
documentation.
• Change the autonegotiation setting, if possible.
• Use another connector on the switch or hub.
If you are using a NIC card instead of an integrated NIC, see the
documentation for the NIC card.
3 Ensure that the appropriate drivers are installed and the protocols are
bound. See the NIC's documentation.
4 Enter the System Setup program and confirm that the NICs are enabled.
See "Entering the System Setup Program" on page 47.
5 Ensure that the NICs, hubs, and switches on the network are all set to the
same data transmission speed. See the network equipment
documentation.
6 Ensure that all network cables are of the proper type and do not exceed the
maximum length.
If the problem persists, see "Getting Help" on page 167.
