I believe ethtool is what you are looking for.

Here's a common problem that I've been running into at companies. Most big companies use a good switch like Cisco, which controls the speed settings as well as the duplex settings.

Most companies have them set to 100Mbps/Full Duplex. If the card is not set to this explicitly, I've noticed a dramatic decrease in network speed.

In your /etc/network/interfaces file, you can add an entry with pre-up or post-up. Refer to the man page interfaces(5).
