I'm running out of ideas about how to troubleshoot this problem and any help would be appreciated. Apple System Profile reports that the built-in Ethernet 'link' is 'down'. I've run an extended Apple Hardware Test, and it's not reporting any logic board issues (see photos).

However, I'm uncertain if there's a problem with the Ethernet port/card in the Pismo itself. So, I've ruled out my network itself (despite having reset both my DSL modem and wireless router to see if that would help). Running a browser or engaging Network Time does not kick the connection into gear. Manually entering an IP address and related information matching my network was unsuccessful. I've tested the same setup with a nearly identical Lombard (400MHz, 128MB RAM), and everything works well (as it does for all my other new and old machines). On both OS 9 and X, TCP/IP reports a 169.x self-assigned address rather than the I would expect.

I recently picked up a Pismo (400MHz, 512MB RAM) and I'm having issues getting it to connect to my network via Ethernet.
