[SOLVED] Interface speed only 10baseT-FD

[user789]

Hi all,

I'm running on Proxmox on a Intel NUC which has a Gigabit lan interface, however the interface speed is only set to 10baseT-FD. When I try to change the interface speed I get the following errors. See output below:

root@proxmox:~# ifconfig

root@proxmox:~# mii-tool eno1
eno1: negotiated 10baseT-FD flow-control, link ok
root@proxmox:~# mii-tool -F 1000baseTx-FD eno1
Invalid media specification '1000baseTx-FD'.
root@proxmox:~# mii-tool -F 100baseTx-FD eno1
SIOCSMIIREG on eno1 failed: Operation not supported


Also good to mention. I've tested the ethernet port on which the NUC is connected on my Ubuntu laptop and I get a gigabit connection immediately.

Does anybody know how to solve this?
Thanks in advance!

mii-tool is very old, please use ethtool for that:

apt-get install -qq ethtool
ethtool eno1

Thanks for your reply. The following command worked for me:

root@proxmox:~# ethtool -s eno1 speed 1000 autoneg off
root@proxmox:~# ethtool eno1
Settings for eno1:
Supported ports: [ TP ]

Supported FEC modes: Not reported
Advertised link modes: 1000baseT/Full

Another work around was changing the network adapter of the VM from VirtIO (paravirtualized) to Intel E1000
