Hi SarunasKa,
I tried this before, but did it again. It was running 7.x and I downgraded to 6.8.5 through the Bootloader menu. The LAN ports are unresponsive and LAN2 is always UP. When I connect through WIFI, I see 2 active LAN ports (1 is my LAN port and LAN2 is always UP). I have added details of the device below:
Kernal: 3.18.44
Bootloader: 3.2.6
