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?
