trying to figure out if it's hardware, I wish I'd figured that out a
month ago because dell would have been shipping me a new mobo at that
point... oh well... I'm starting to think it is but given the age of
the computer... (just over 1 year now) I'm not happy about that. my
nic is a 10/100 card the e1000e is obviously gigabit though I don't
think I've a need (or network) for the gigabit atm
