I think some update has caused this to happen, probably about 5 days
ago (noticed
something was slow). These are KDE/Plasma GUI systems but I'm not
sure if this is
due to a change in KDE/Plasma, NetworkManager or something else.
The KDE/Plasma NeworkManager settings GUI interface now has an "Allow
auto-negotiation" checkbox which I don't think was there before and
there is now
the entry ETHTOOL_OPTS="autoneg on" in the
/etc/sysconfig/network-scripts/ifcfg-*
file if you set it. It appears that the default setting is
100MBits/s half duplex
rather than auto negotiate...
All of my bare metal systems are KDE only. All of them are fully
update. All of
them are running at....
Speed: 1000Mb/s
Duplex: Full
The "Allow auto-negotiation" box has been there for as long as I can
recall. As a
matter of fact, there was (maybe still is) a bug that prevents saving
configuration
changes if that box is not checked.
What are the systems connected to? You may want to reset it?
I am using a home plug device to get ethernet access across the home
electrical wires. The home plug device is provide 500 Mb/s, so having
seen this thread I've checked my ethernet configuration and like Terry
is saying my settings have auto negotiate unchecked and the link speed
is set at 100 Mb/s and Half Duplex. I have not explicitly set that
configuration but what I don't know, because I haven't really taken
any notice of it as I only use this connection as a backup to
wireless, is whether or not those settings have always been there. I
have done any changes to the configuration since I set it up in F26.
Just further to this, on my system when the auto negotiate box is
checked the link entry and the duplex entry are removed from the dialog.
