Ethtool script not running on boot.

Hi, there is an incompatibility between my NIC and my Western Digital Powerline adapters which appears to cause autonegotiation to fail intermittently, most often following a reboot. Running the following Ethtool script will establish a connection immediately:


# chkconfig: 345 85 15


SPEED="100 duplex full"
case "$1" in
echo -n "Setting eth0 speed 100 duplex full...";
$ETHTOOL -s $DEV speed $SPEED;
echo " done.";;
exit 0

I have tried placing this script in /etc/init.d, and it is shown as a selected option when running
ntsysv but to no avail.

The recommended method for Fedora is to add
ETHTOOL_OPTS="speed 100 duplex full autoneg off" to /etc/sysconfig/network-scripts/ifcfg-NameOfConnection which again is not working.

I'm running Fedora 15 64-bit, NIC = Intel 82562V-2 10/100.

If anyone is able to help out then they would probably save my hair from being wrenched out. Thanks

does the directive:


not work in your /etc/sysconfig/network-scripts/ifcfg-ethX file?

that is how most people go about adding those options sanely.

Thanks but afraid that didn't work either, here's my config:

NAME="Wired connection 1"
ETHTOOL_OPTS="speed 100 duplex full autoneg off"

No new firmware available so probably no fix for the underlying incompatibility but I'll give Intel's proprietary drivers a try as they may include a configuration utility - this is how I solved the problem on my Windows 7 install.

Probably won't have a chance to do this until quite a bit later today.

Can't compile the intel e100 driver - it keeps failing and advising that it can't install on kernel's older than 2.4 when I'm using 2.6.40. Removed the coding from the Makefile that stops it proceeding but I have no faith in the installed result as there was a long list of errors following make install.

Driver in use is intel's e1000e.

To be honest I'm about ready to give up on this and just purchase a new NIC, it's been an ongoing problem for some time.

how are you doing this? Why is it trying to compile the E100 driver when you are using a gigabit adapter?
