Hello, I have Minix Neo X7, and same problem with internet on it, so I used WiFi-dongle to install armbian-firmware-full. It didn't help me with ethernet, but also I lose my HDMI-output
Maybe this problem also was caused by upgrading packages, but I newbie to ambian, so I don't know which algoritm to deal with those problems.
If someone interested, output of armbianmonitor: http://ix.io/3xyR
