I need a method to use Intel I225 network cards in ubuntu18.04.

[bangbang_dep]

Hello.
I need an Ethernet connection after installing Ubuntu18.04 using TOP500B (R100) products.
TOP500B products are
@ @ Processor System
-Onboard Intel 11th Gen Tiger Lake-U series processors
- - EFI BIOS
@ @ Intel I225 2.5G network cards (single and dual network optional)
It is.

The main question is
1. Is there no way to use the I225 Ethernet controller with Ubuntu 18.04?
2. Ethernet controller driver not found.
Can you make and use Ethernet drivers with a simple design?
3. If I don't support Ubuntu 18.04, can I know why I don't? Or I wonder if it will be updated later.

Thank you for your reply to the email below.

Hello @bangbang_dep,

Thank you for contacting Intel Embedded Community.

In this link you can check the Supported Operating Systems for Intel® Ethernet Controllers:

https://www.intel.com/content/www/us/en/support/articles/000055236/ethernet-products/gigabit-ethernet-controllers-up-to-2-5gbe.html

You may need to update to a newer version, it mentions that Ubuntu* 22.04 is supported by the igc driver.

Best regards,
