Can't find any ugreen adapters in my country so i'm looking for alternatives.
I was looking at a TP-Link UE300 but people have said that tp-links don't work that well (because they have realtek interface?) so i looked for something else and found Trendnet TU3-ETG. Would the Trendnet work well?
I just want something that dosen't disconnect randomly like the wifi does.
The same model of USB ethernet adapter does not always have the same chipset. It is incredibly annoying. If you have been using linux for years you learn this stuff, often the hard way. The android kernel is linux, and often not running on x86 which further limits your choice. So, it is unlikely that anyone will be able to tell you that the adapter you are purchasing will work or not.
TL;DR - just buy a ugreen usb 3.0 hub with gigabit internet, it works stably, and gives you additional usb ports.
Get it on AliExpress, they ship worldwide.
I'm using this and it works perfectly: AmazonBasics USB 3.0 to 10/100/1000 Gigabit Ethernet Internet Adapter https://www.amazon.com/dp/B00M77HMU0/ref=cm_sw_r_cp_apa_i_SZMmDbHSFTR44
Not sure about its availability in other countries
I bought the amazonbasics one. Works like a charm.

I bought this one and it works for my Mi Box. I don't have the S though so I can't say for sure.
