DaMadFidler, I haven't read this in extreme detail as I am not particularly interested in the SE/30 as my user name suggests.

However, I know you have searched for other things, have you searched the forum for SE/30, Ethernet, and Internet? If so , add JDW as a user post name and limit to Compact Macs. He has written a collective tome on getting an SE/30 online, accelerating it and routinely accessing the internet. I would be surprised if every answer you needed wasn't there.

Actually I'm surprised he hasn't chimed in on this topic yet. Must be busy.
