Not much info to go on here.

Look in /var/log/messages, starting when you know the connection was up 
until you knew it was down. Look for messages regarding the network, 
drivers or anything else that might give you a clue.

If you want more specific help, you need to ask more complete questions. 
What kind of hardware do you have? What is the network card plugged 
into? If it's a managed switch, look at it's logs to see if it says 
anything about the given port.
