The Gigabit Adapter will work shitty as your connection is just USB 2.0 - if you don't force it to 100 Mbit/s it won't work stable at all. I play such files with AC wireless, get up to 50 MegaByte / s.

I thought about it this morning, and indeed, I suspected that a gigabit adapter would not work well on USB2.0 ... However, instability? :o

I've been using the UGREEN USB 3.0 Hub Ethernet Adapter 10/100/1000 Gigabit Adapter on my Fire TV Stick 4K since day 1, never a single issue with network or device instability.  Using this adapter via the USB 2.0 port on the 4K requires a microUSB OTG cable such as this one.  The UGREEN Network Adapter USB 3.0 to Ethernet RJ45 Lan Gigabit Adapter would also work just fine if you don't want the additional USB ports.

Using a USB 3.0 Gigabit Adapter on the 4K gives me a stable 320-330Mbit download when I test via analiti on my gigabit network connection and buffer free streaming of files with greater than 50,000kbps data rate over my network via NFS from my Linux file server.
