My system is using Realtek RTL8111C Ethernet controller.  When I insert the loopback dongle in the Ethernet port, I don't get a valid LINK under Windows XP Pro.  The LINK LED turns off and Windows doesn’t recognize anything being connected to the Ethernet port, reports that “A Network Cable is Unplugged” even though the dongle is connected.  So I can't run the Network loopback test.

Any idea as to how I can get the test going.  Thanks.

Maria,

Most Gigabit Ethernet cards will not work with the loopback connector.  To perform the link and loopback test plug the card into a valid network.  By valid I mean one that has a DHCP server and a gateway.  The software will perform all needed tests in this environment.

Fred,

Thanks for the reply.

I am a little confused to your command above. 
Does it mean that you don't use the loopback dongle, and just connect to a valid network, and run the network test?

Thanks,

Maria,

You are correct, don't use the dongle and just plug it into the network.  Put the loopback dongle back in the bag.
