Ethernet controller troubleshooting chart
You can use the following troubleshooting chart to find solutions to 10/100 Mbps
Ethernet controller problems that have definite symptoms.
Make sure that the cable is installed correctly.
The network cable must be securely attached at all connections. If the cable is
attached but the problem persists, try a different cable.
If you set the Ethernet controller to operate at 100 Mbps, you must use Category
5 cabling.
If you directly connect two workstations (without a hub), or if you are not using a
hub with X ports, use a crossover cable.
Note: To determine whether a hub has an X port, check the port label. If the label
contains an X, the hub has an X port.
Determine if the hub supports auto-negotiation. If not, try configuring the
integrated Ethernet controller manually to match the speed and duplex mode of
the hub.
Check the LAN activity light on the rear of the computer. The LAN activity light
illuminates when the Ethernet controller sends or receives data over the Ethernet
network. If the LAN activity light is off, make sure that the hub and network are
operating and that the correct device drivers are loaded.
Make sure that you are using the correct device drivers, supplied with your
computer.
Check for operating system-specific causes for the problem.
Make sure that the device drivers on your computer and the server are using the
same protocol.
Test the Ethernet controller.
The way you test the Ethernet controller depends on which operating system you
are using (see the Ethernet controller device driver README file).
