Re: [SLE] Lost network connection -- how to diagnose?

I now have more info on the problem: disabling the on-board ethernet module and installing a separate card brought me my connection back. That would seem to indicate a hardware failure. But to verify or refute that, here's the beginning of what showed up in the system log: eth0: Transmit timed out, status 003, PHY status 786d, resetting IRQ 10: nobody cared! Can anyone interpret that? Am I dealing with a driver problem or a hardware problem? Just to clarify: ping localhost worked but pinging anything other than the host led to "network unreachable" errors. Paul
