[SOLVED]Ethernet won't connect

[corkncat]

I'm using Ubuntu Server 22.04.4 LTS. Ethernet won't connect but when I added a WiFi card I can connect. I opened a terminal and type: "sudo lshw -C network"
This is what I got concerning my ethernet:
*-network DISABLED

How do I enable it? I checked the BIOS and it's enabled there.
Thanks

This is long winded but this explains what happened in detail. My hope is that it will help someone else.
I was using an old Dell pc from the Windows Vista days to serve as my home NAS. It had Ubuntu Server 22.04,
4GB RAM, 1 SSD with the OS and 3 HDD for storage. The hardware was no longer working properly so I bought a
used mobo, cpu & RAM combo and a new case. I then transferred my drives to the new hardware. It booted
fine but had no internet. I installed a wifi card and had access but ethernet port was disabled. After much
research this is how I got it working.

Static IP

In order to setup a network interface with a static IP, we have to create its corresponding file:

$ sudo vim /etc/systemd/network/00-enp3s0.network

With this content:

[Match]
Name=enp3s0

[Network]
Address=192.168.1.27/24
Gateway=192.168.1.1
DNS=192.168.1.1

DHCP

With DHCP we follow the exact process above and change the configuration file content to:

[Match]
Name=enp3s0

[Network]
DHCP=yes

Restarting the service

Once we are done with our changes, it is required that we restart our service

$ sudo systemctl restart systemd-networkd
