Connection Issues with Intel i219 Network Interface on Ubuntu Server 20.04
If you're experiencing connection issues with the Intel i219 network interface on an Ubuntu Server 20.04 system, follow these steps to update the driver and configure the network settings.

Step 1: Update the Network Driver
Download the e1000e driver:
First, ensure you have access to the driver file e1000e-3.8.4.tar.gz. You can download it from the Intel website or https://www.jetwayusa.com/dl/driver/intellan-i219-linux.zip
Extract the driver package:


$ tar -xzf e1000e-3.8.4.tar.gz
Navigate to the driver directory:


$ cd e1000e-3.8.4
Compile and install the driver:


$ sudo make install
Load the new driver:


$ sudo modprobe e1000e
Verify the driver installation:


$ sudo lshw -C network
Ensure the driver=e1000e is listed under your network interface details.

Step 2: Configure DHCP Settings
Edit the Netplan configuration file:


$ sudo nano /etc/netplan/00-installer-config.yaml
Add the following configuration to set DHCP for your network interface (replace eno1 with your actual interface name if different):
example
network:
  ethernets:
    eno1:
      dhcp4: true
  version: 2

Save the file and exit the text editor.
In Nano, you can do this by pressing Ctrl + X, then Y to confirm saving, and Enter to exit.
Apply the Netplan configuration:

$ sudo netplan apply
