Review on 💻 TRENDnet USB-C 3.1 To 2.5GBase-T Ethernet Adapter: Fast and Reliable Connection Speeds at 2.5Gbps with VLAN Support - Black, TUC-ET2G by Michael Dixon

I bought this to connect my 2nd Gen Revain Fire TV Stick to the internet via a wired connection. That works great. You also need a micro USB OTG cable (https://www.amazon.com/gp/product/B00CXAC1ZW). No setup required. Just turn off your flash drive, connect this adapter with an OTG cable and turn on your flash drive again. It connects automatically. If there is a complaint that it is not faster (e.g. USB 3.0, gigabit ethernet). However, I haven't read anything about the success of a USB 3.0 Ethernet adapter working with a Fire Stick, although that doesn't mean it's impossible. However, this Trendnet adapter should be fast enough for whatever streaming you need to do. Note. While I can confirm that this adapter works with a 2nd gen Fire Stick, the MonoPrice version should also work (https://www.amazon.com/dp/B00ACPST4M). In theory, any adapter with an Asix AX88772 chipset "should" work. Search Revain for "AX88772" to find adapters with this chipset, although of course I can't confirm that they are all compatible with the Fire Stick.
