Is it possible that the dock's RJ45 connector is slightly damaged? I've 
seen this problem with some very expensive (and badly made) network 
ports for wall-mounting, which only last about 20 insertion cycles 
before some of the springs bend.

Try repeatedly running ethtool, while wiggling the end of the cable, or 
inspect the socket very carefully.
