i am in the same boat with network connection failures over wired ethernet between my mini10v(10.6.2) and my mac pro1,1 (10.6.2). wireless is fine, but i am trying to back up drive clones of the mini to one of my backup disks on the mac pro along with other large file transfers.
i have tried standard and crossover cables (just in case, though shouldnt matter), no luck
i have successfully connected my G4da to my mac pro over ethernet, so seems to be an issue on the mini side.
any insight? could be missing something simple here...
by no means an expert with all this, but have held my own getting the mini up and rolling flawlessly (with countless hours perusing this site, THANKS TO EVERYONE FOR ALL THE POSTINGS AND SUPPORT OF EACH OTHER, WHAT A GREAT COMMUNITY, I HOPE I CAN RECIPROCATE SOMEHOW), so i can get in there and tweak around no problem if anyone has suggestions
