As a nerd, let me make this easier. The speed is better when your device is connected via Ethernet. My internet package has 175 Mbit/s. Wi-Fi has two options: 2.4 GHz and 5 GHz. With the Firestick I was at 60Mbps over 2.4GHz and 75-80Mbps over 5GHz. I installed an ethernet adapter and now it's 173Mbps. (Internet Service Provider rarely gives you the maximum speed) That's pretty damn good. Take it!
