Network Problems
Problem
Cause
Solution
Wake-on-LAN feature is not
functioning.
Wake-on-LAN is not enabled.
Use the Network control application to enable
Wake-on-LAN.
Network driver does not
detect
network controller.
Network controller is disabled.
Run Computer Setup and enable network controller.
Incorrect network driver.
Check the network controller documentation for the
correct driver or obtain the latest driver from the
manufacturer’s Web site.
Network status link light does
not turn on or it never flashes.
The network status light should
flash when there is network
activity.
No active network is detected.
Check cabling and network equipment for proper
connection.
Network controller is not set up
properly.
Use the Network control application to verify that
the device is working properly.
Network driver is not properly
loaded.
Reinstall network drivers.
System cannot autosense the
network.
Disable auto-sensing capabilities and force the
system into the correct operating mode.
Diagnostics reports a failure.
The cable is not securely
connected.
Be sure that both ends of the data cable are
securely connected.
The cable is attached to the
incorrect connector.
Be sure that the cable is attached to the correct
connector.
There is a problem with the
cable or a device at the other
end of the cable.
Be sure that the cable and device at the other end
are operating correctly.
Network controller interrupt is
shared with an expansion
board.
Under the Computer Setup
Advanced menu,
change the resource settings for the board.
The network controller
is defective.
Replace the NIC.
Diagnostics passes, but the
workstation does not
communicate with the
network.
Network drivers are
not loaded, or driver
parameters do not match
current configuration.
1.
Be sure the network drivers are loaded and that
the driver parameters match the configuration
of the network controller.
2.
Be sure the correct network client and protocol
is installed.
The network controller is not
configured for this workstation.
Select the Network icon in the Control Panel and
configure the network controller.
