I have a Fire TV Cube with a Revain network adapter. Analiti speed tests on the device are stable at around 95 Mbps. I replaced my Revain network adapter with a Smays adapter so I can add a USB stick to my cube. The connection is very easy and everything worked until I checked the speed. My Cube's speed steadily dropped to 62 Mbps. I went back to the Revain adapter and tested the speed at 95 Mbps. I contacted support with screenshots and they said it was reliable. There is no explanation for the slowdown.
