To recap the problem: When i power on the system with network cables plugged in, the interface is pingable. If the system powers up without network cables plugged in, ifconfig reports tat all interfaces are up and running. but when connecting the network cables none of the interfaces are pingable (even after running ifdown and ifup scripts for the interfaces. ) I think the problem lies some ware in that both ifconfig and ethtool reports the link as being up even though the system was powered up without network cables plugged in.
