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 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 website.

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.

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.

CAUTION:

Disconnect AC power from the workstation

before reseating or replacing components because there

is power to the system board even when the workstation

is powered down.

Replace the NIC.

Diagnostics passes, but the

driver parameters do not match

current configuration.

Be sure the network drivers are loaded and that the

driver parameters match the configuration of the

network controller.

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.

Network controller stopped

working when an expansion

board was added to the

workstation.

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 requires

drivers.

Verify that the drivers were not accidentally deleted when

the drivers for a new expansion board were installed.
