"no carrier" usually means the ethernet cable is not connected or loose.

"late collision" means a long packet suffered a collision after the 1st
	64 bytes, which in turn means that your ethernet is mis-configured.
	A late collision means the distance between distant parts of the
	network is more than 64-byte times.  The most common error is
	using excessively long drop cables.  With at least some twisted
	pair transceivers, you're limited to 10 or 20 feet.  It is also
	easy to break thick net by using three or more 75 meter 
	drop cables.
