Hi
very important update to you:
I have connected the Mac Mini G4 via ethernet directly to the Router ADSL (so no Cisco switch and no appliance hardware Watchguard) and I have the same problem ... always 7 or 10 or 15 kb/s in MorphOS 2.4 (no problem rebooting in OSX Leopard 10.5.8).
I think this can help a little
Tell me if you need help to verify something to solve the problem.
(Ruter adsl is Zyxel 660H-T)
THANKS for the support.
