ethtool -s eth0 speed 1000 duplex full autoneg off In my case it's peth0.


Other commands:

lspci |grep Ethernet

dmesg |grep eth0

ethtool eth0

ethtool -k eth0

ethtool -S eth0

To make the changes permanent, edit /etc/sysconfig/network-scripts/ifcfg-eth0 add ETHTOOL_OPTS="speed 1000 duplex full autoneg off"
