What's lspci -k  show?  I have a very temperamental  nic in a Debian box. I
elected to use an intel pci nic and ignore the onboard one.

Is this a hardware not detected (modules loaded) issue?  It's possible your
nic is working fine, but dhcp isn't always assigning the nic an address.
Have you configured any of your routers/switches/etc to use a fixed speed?
some Ethernet equipment stops advertising link capabilities (auto
negotiation) when one of the properties is manually configured.
