Can't set speed for network card
 

I need to set my network card to 100baseT/Full Duplex. Turning off auto negotiation.

I have tried...
mii-tool eth0 --force=100baseTx-FD

It seems to work temporarily but the setting won't survive a reboot. How do I make it permanent? Help.

You need to add the line to one of the startup scripts. These are usually found at /etc/rc.d/init.d. /etc/rc.d/init.d/network is probably the best bet.

IDoes anyone know if there an easier way to do it other than hard code it in the startup script? I wouldn't know where to place it in the script.

To make things easy you can add the command to /etc/rc.local.
