[SOLVED] Network is unreachable afrer fresh classic install on old rig

Hello I'm newbie here. Yesterday I installed arch for the first time. I'm lamer but I managed the installation according to install guide and with gpt manual partitioning and bios boot partition and separate /boot etc. It's last pre uefi bios MB but now upgraded with hardware raid card. I had tumbleweed installed before on this old pc and everything worked. Now it boots arch (from raid card), but I'm stuck in terminal and can't install plasma-meta package or do -Syu or anything.
I can write here some outputs.
ping: google.com: Temporary failure in name resolution
ping 192.168.88.1 (mikrotik router) : Network is unreachable.

I'm quite frustrated when so basic think doesn't work and thinking about tumbleweed again. Yesterday I spend whole day by installation and then tried to fix the connection but unsuccessfully. I was reading the network configuration page on arch wiki and it appears that systemd-networkd manager is instaled as default network manager. But systemctl restart systemd-networkd didn't help.
In live enviroment I had the connection but after installation no. I think something is missing in this install but according to lspci the kernel module driver of gigabit ethernet controller is loaded. Its old Marvel 88E8056, and there are 2. On other linux distros live enviroments it worked with no problems.
I don't know if photos are allowed directly in this forum. I have some 12mpx photos of screen but it's not so comfortable for me to post photos from tablet. Now I'm on USB live system (ventoy gentoo).

If you want to use systemd-networkd, you have to configure it first. See the wiki page for it, or the man page. How things work on the ISO have no bearing on the installed system.

Arch doesn't enable services by default.

I did it according to wired DHCP configuration example in systemd-networkd wiki page. https://wiki.archlinux.org/title/Systemd-networkd
Created /etc/systemd/network/20-wired.network file.
First see output of,

networkctl

Then edit the 20-wired.network file according to wiki page.
In my system:

[Match]
Name=enp9s0

[Link]
RequiredForOnline=routable

[Network]
DHCP=yes

Lastly,

systemctl enable systemd-networkd systemd-resolved

OK, this was trivial.
