Wired network not working

Hi,

I am fighting with my wired network connection now for two days.
I receive an IP via dhcp, routing is set correctly, dns is added, so basically everything looks good, but I can't reach anything, not even the gateway.

I am currently using NetworkManager, but I already tried netctl and wicd, same behaviour with all three.

Strange is, if I execute:

ethtool -s eno1 speed 100 duplex full autoneg on

I can ping the gateway and dns server for a few seconds and then it stops again.

Maybe you guys can help me to get my wired network working.

Best regards,

Merl

Edit: I checked logs ( journalctl ) too and I couldn't find anything suspicious...

Re: Wired network not working

Welcome to Arch Linux.

I see you have tried several tools.  They don't place nicely together, so be certain you only have one enabled at a time for systemd.  Also, those services do not play nicely with the systemd dhcpcd.service. The dhcpcd.service will start the dhcpcd daemon.  so will wicd, NetworkManager, et al.

If you don't have Wireless on this system, get rid of all that, er, stuff.  Disable NetworkManager, netctl, and wicd entirely.  I'd even uninstall them.
Reboot.  Run (as root) dhcpcd and let's see if that just works.

If it does, enable the dhcpcd service using systemctl.  The next time you boot, it should be good to go.
