Problem Lan Network rj45 in banana pi m6

Hi, I just got my Banana Pi m6, and it has really good hardware, but I’ve noticed a problem running the Ubuntu distribution on different builds. The LAN adapter isn’t working. I’ve modified etc/network and added both DHCP and a static IP, but I don’t get any results even after restarting the service via systemd. Could you tell me what the problem is with the LAN adapter? The activity LEDs aren’t turning on.
