There are known problems with the later 3com 3C905C cards which often
fail to autonegotiate correctly. As far as I know, the earlier cards
don't suffer from this, but I guess it's possible. It may be worth
comparing manufacture location of the cards - apparently there are a few
differences between cards originating from Ireland and those originating
from Singapore. See for example (although it refers to Linux)
