Forcing ethernet link speed to 100MBit/s via the GUI doesn't work #129

Any clues how to disable autoselect permanently. I need this for a device which doesn't work at 1GBps.

Auto-negotiation is usually quite reliable. But not always (I have been bitten by both flaky cables and flaky devices).

You can set interface to a specific speed with ethtool. This post suggests making permanent by adding this command at the end of /etc/network.d/if-pre-up.d/ethtool

# add to end of /etc/network.d/if-pre-up.d/ethtool to force 100Mb/s
$ETHTOOL --change eth0 advertise 0x008
