High Bitrate 4K HDR Rips with 5.1/7.1 lossless HD audio need a device with Gigabit Ethernet.
1) Add a Realtek or ASIX Chipset - USB3 > Gigabit Ethernet adapter to 100Mbit only Ethernet boxes, some even come with USB Hubs like the Ugreen ones.
2) Get either a S912 or S905D AML box - make sure it is Gigabit Ethernet equipped aka 1000M
But only what I need is to open movies from mkv/m2ts files. Not streaming. I don't need gigabit ethernet
