The Ubuntu Linux requires a Realtek USB LAN Update which is not included by default.

Advise the customer to update BIOS to v1.15.0 or later, and run the following commands to update:

1. Run sudo apt update to update sources.
2. Run sudo apt install linux-firmware starts update 20220329.git681281e4-0ubuntu3.10 (Dell OEM Ubuntu) or 20220329.git681281e4-0ubuntu3.3 (Stock Ubuntu) to install 20220329.git681281e4-0ubuntu3.26 which contains the required fix.
3. Reboot the computer and verify that the problem has been resolved.
