You want to look at ethtool or mii-tool.

ethtool -s eth0 speed 1000 should force the card to gigabit... watch
for errors and check /var/log/messages and dmesg output for any issues.

You might tweak with the duplex settings as well (see man ethtool)

Are you at the latest kernel/updates for your system?  Perhaps newer
drivers would address your problem.
