| Code: | # dmesg | grep eno1
[ 1.936841] e1000e 0000:00:19.0 eno1: renamed from eth0
[ 12.935956] e1000e 0000:00:19.0 eno1: NIC Link is Up 1000 Mbps Full Duplex, Flow Control: Rx/Tx
[ 17.920083] e1000e 0000:00:19.0 eno1: NIC Link is Up 100 Mbps Half Duplex, Flow Control: None
[ 17.920086] e1000e 0000:00:19.0 eno1: 10/100 speed: disabling TSO |
If I run
ethtool -s eno1 speed 1000 duplex full
It switches to Gigabit and I'm good, until I reboot and it goes back to 100.... |

Put the command in /etc/local.d/baselayout1.start.

I had this problem with Realtek r8169.
I had samba mounts in /etc/fstab and did not have netmount activated. This gave mount a big problem. it seems to have giving net.eth0 a problem finishing. So net.eth0 timed out and connected at a slower speed.
the solution was "rc-update add netmount". Then mount didn't try to mount the samba shares and net.eth0 connected at 1Gbps mount completed and the shares were mounted after net.eth0 and mount by netmount. |

Thanks everyone for the suggestions. I had switched to systemd at one point because of some needs to test it. I wonder if its something to do with that or the fact I'm using networkmanager.
I'll play around with it and post anything I find. Already did a hardware check, tried a different cable & switch. It works perfectly after running ethtool, so I think it's a software issue. |

I just realized I had this problem too. It was totally NetworkManager.
I fixed it by going into the connection settings for the ethernet, and changing "Link Negotiation" to "Automatic." |
