System is configured for AUI connection; link LED does not apply to AUI connections. 4. Network driver is not properly loaded. Reinstall network drivers. 5. System cannot autosense the network. Disable autosensing capabilities and force the system into the correct operating mode. Diagnostics reports a failure. 1. The cable is not securely connected or is attached incorrectly. Ensure that the cable is securely attached to the network connector and that the other end of the cable is securely attached to the correct device. 2. There is a problem with the cable or a device at the other end of the cable. Ensure that the cable and device at the other end are operating correctly. 3. The network controller is defective. Replace the controller or the system board. 4. Network controller interrupt is shared with an expansion board. Under the Computer Setup Advanced menu, change the resource settings for the board. Diagnostics passes, but the computer does not communicate with the network. 1. Network drivers are not loaded, or driver parameters do not match current configuration.

Troubleshooting Without Diagnostics
Network
Some common causes and solutions for network problems are listed in the following table. These
guidelines do not discuss the process of debugging network cabling.
Problem
Possible Solution
The Remote Wakeup feature is
not functioning.
1.
The feature is not available when using an AUI network connection;
use an RJ-45 network connection.
2.
Remote Wakeup is not enabled. Use the network control application
to enable Remote Wakeup.
Network driver does not detect
network controller.
Network controller is disabled. Run Computer Setup and enable
network controller.
Network status link light does not
turn on or flashes.
1.
No active network is detected. Check cabling and network
equipment for proper connection.
2.
Network connection is not set up properly. Use the network control
application to verify that the device is working properly.
3.
System is configured for AUI connection; link LED does not apply to
AUI connections.
4.
Network driver is not properly loaded. Reinstall network drivers.
5.
System cannot autosense the network. Disable autosensing
capabilities and force the system into the correct operating mode.
Diagnostics reports a failure.
1.
The cable is not securely connected or is attached incorrectly.
Ensure that the cable is securely attached to the network connector
and that the other end of the cable is securely attached to the correct
device.
2.
There is a problem with the cable or a device at the other end of the
cable. Ensure that the cable and device at the other end are
operating correctly.
3.
The network controller is defective. Replace the controller or the
system board.
4.
Network controller interrupt is shared with an expansion board.
Under the Computer Setup Advanced menu, change the resource
settings for the board.
Diagnostics passes, but the
computer does not communicate
with the network.
1.
Network drivers are not loaded, or driver parameters do not match
current configuration. Make sure the network drivers are loaded and
the driver parameters match the configuration of the network
