Public bug reported:
As far as I can tell, ethernet cards usually behave just fine if allowed
to autonegotiate speed and duplex. Sometimes, though, this doesn't
work. A user should be able to force, for example, 10BaseT/half duplex
for their ethernet connection(s) by right clicking on the network-
manager applet, going to Edit Connections..., the Wired tab, editing the
interface in question, and finding the option in, say, the "Wired" tab
on the "Editing Auto eth0" window that pops up.
I ran into this when dealing with an old wired network at work (a
university). Autonegotiation fails under all operating systems and all
ethernet cards (that I tried), and the well known solution in other OSes
is to manually set the speed/duplex to 10BaseT/half. In OS X, e.g.,
this is right where you'd expect it, near the options to setup your
wired connection manually instead of using DHCP. On my ubuntu jaunty
system, though, I had to do
sudo ethtool -s eth0 autoneg off speed 10 duplex half
then put it in my /etc/rc.local to make it persist. Wouldn't this fit
in just fine in nm-applet?
So for completeness:
$ lsb_release -rd
Description: Ubuntu 9.04
Release: 9.04
$ apt-cache policy network-manager-gnome
network-manager-gnome:
Installed: 0.7.1~rc4.1-0ubuntu2
Expected to find options to set ethernet speed/duplex via network
manager, didn't find it.
Had to do it via command line.
