On my Ugoos X3 Plus, if I use meson-g12b-odroid-n2.dtb , I can use ethernet port and dmesg and other linux tools say that I have giga network connectivity while speedtest.net just show a fraction of the right speed... I won't be able to get wifi working with odroid-n2 dtb file but if I use sm1-sei610.dtb, wifi is good but it can't see connected ethernet cable.
