[SOLVED] Ethernet not working after reinstalling kernel

Coming from this post: [link=https://bbs.archlinux.org/viewtopic.php?id=295393][SOLVED] System not able to boot after removing files not owned[/link]

I had to reconfigure all the system and all modules in mkinitcpio.conf went back to default. My ethernet connection is not working anymore, I managed to get wifi working but ethernet not.
I tried following the wiki instructions but when talking about ethernet all shoud work out of the box.

$ lspci -v

25:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet Controller (rev 15)
	Subsystem: Micro-Star International Co., Ltd. [MSI] Device 7c52
	Flags: bus master, fast devsel, latency 0, IRQ 36, IOMMU group 14

	Kernel driver in use: r8169
	Kernel modules: r8169

# dmesg | grep r8169

$ ip address show

    link/ether 2c:f0:5d:d6:5e:2b brd ff:ff:ff:ff:ff:ff

$ cat /etc/mkinitcpio.conf

MODULES=(amdgpu)
BINARIES=()
FILES=()
HOOKS=(base systemd autodetect keyboard keymap modconf block filesystems fsck kms)

For using wifi I started iwd (is disabled usually) and used an external anthena, this commands outputs are without it.

Everything looks fine, what's the problem? What are you running to configure the connection?

Got it working after configuring DHCP in systemd-networkd.
