Re: NM looses connection and/or doesn't use dhcp

Ok, I understand this when it applies to wireless.  But as I have said 
in my post I am talking about my wired connection.  With wireless, yes, 
it makes sense.  But with a wired connection that IS NOT dropping then I 
would expect NetworkManager to stay connected to it.  I sometimes leave 
my laptop on at home and connected to the wired connection.  Then at 
work I attempt to ssh into it only to find that it is "down".  This is 
the reason I posted on here as it looks to be a serious bug.  Now in all 
honesty it has stayed connected today for at least three hours so this 
is good.  One possibility is that my wired connection becomes congested 
and very slow sometimes, but that shouldn't matter because it is still UP.
