	thanks for the response! Note, ethernet *was* working and then stopped, with no obvious action on my part. That said, answers in-line below.

Mac OS 10.4.11, classic installed.

I don’t know the answer to that. I got it used, and don’t think I have updated it.Is there a good way to tell?

I probably can still have my 9.x install dask - I’ll look - and my 10.4 disk. I”m pretty sure there are things I’ll lose doing 2 re-installs, but maybe I can back them up to a USB memory to restore.

Not yet, but will do, hopefully tonight. Does direct (ethernet) connection to another Mac, sharing its wi-fi to computers using ethernet, count in this context? But I also have a hub built into a retired (DSL) modem which I’m thinking about installing there to free up the 8-port hub; this can motivate me to do that sooner.

One other thing I forgot to mention: iPv6 broke this machine’s internet a few months back; so I disabled it through the System Preferences check-box, and it came back up immediately on ipV4. Same thing happened at the same time to the PowerBook G4 (also on 10.4.11) so I attributed that to the service provider (and they actually notified us that they were changing to v6).
