Network Card Issue

[Andrew.Bridgeman at corusgroup.com]

Thanks for the info. I have just run "ethtool eth0" and it says that I am
running at 10Mb/s Full Duplex  but I  do have auto negotiation on so I am
unsure as to why it is running at such a low speed and not using the card
at full speed? Any Ideas why before I have a go doing the  command you
suggested below?

Regards

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.
