errors with eth0, cannot get connected

[Antonio Olivares]

Dear all,

    Yesterday, I successfully applied the updates, but in the afternoon, my computer lost the connection  to the internet.  Now, I cannot get the updates.  I have changed the cat5 cables and to no avail, I cannot connect to the network.  Here's what I have attempted to do

I even installed a pci network card and try to use it to connect with no success.  Please help/advice as the actions to take and get back to testing.
