I think the command you seek is:

Code:

ifconfig ra0 down

to bring it back up:

Code:

ifconfig ra0 up

remember to correctly replace ra0 with your interface (ath0 wlan0 eth0 eth1 etc etc etc!)

replacing it with eth1 worked thanks

How can I run this in a script at boot and shutdown (as it seems to require a sudo permission)? I am having eth0 problems when I boot, and I suspect it is because of the enabled eth0 connection at shutdown (I am running x86 11.04).

Thanks in advance.
