After rebooting to new system no network connection
"ip a" say that link is present(enp3s0: <broadcast,multicast,up,lower_up>)but ping say that "temporary failure in name resolution"

Assign an IP address for your network device like.
ip a add 192.168.1.200/24 dev enp3s0

Add route that points to your router's LAN address
ip route add 192.168.1.0/24 via 192.168.1.1

Change the network and router IP address to match your network.

Oops,

ip route add default via 192.168.0.1

Make sure you change the addresses to match your network.

Check post 5 for correct syntax.
