Amazon uses slower 10/100 Ethernet on the Fire TV Cube and other devices because you really don't need a faster Gigabit connection. I understand you want to know what is the max Ethernet speed of your Amazon Fire TV Stick 4K Max. If you're using Amazon Ethernet adapter then it is a 10/100 device, 10 being the lowest and 100 being the max value.
So I bought this upon recommendations from people here at the UK store for my 4K Max. It didn't increase the speed from what I was using which was the Amazon Ethernet adapter. Has anyone managed to get an adapter that will go above 100 Mbps.
I have a 500 Mbps modem but simply not feasible to use WiFi where I'm at. Unlike a normal TV, a Amazon Fire TV is dynamic for streaming shows and games. However, if yours is lagging, there are ways to increase your internet speed.
Is the Fire TV ethernet adapter speed lower than the ethernet plug-in speed? Since the fire cube ethernet adapter is an added component, there will be a loss in speed in the connection compared to a straight ethernet plug. Fire TV Cube: 40 Mbps WiFi → 400+ Mbps Ethernet (10x faster) These real-world tests demonstrate the massive boost Ethernet adapters provide across all Firestick models. Even if your internet plan maxes out below these speeds, you'll still benefit from the fastest, most reliable connection possible.
Ethernet vs WiFi Speed Comparison. Then, running the Speed Test app on my Fire TV out in the living room (about 20' away), I get around 70mbps using WiFi. But then when I run a brand new 50' Cat-6 Ethernet cable straight from the router to the Fire TV, I'm getting around 30mbps.
Your Amazon Fire TV Stick deservers a dedicated Ethernet adapter for fast internet speeds. Check the top five picks on our list. The Amazon Fire TV Ethernet Adapter uses only a 100Mbps connection, so 80Mbps actual seems about right.
No streaming service approaches that bit rate, so the only thing a faster connection would gain you is faster app downloads. Plug the USB Ethernet adapter into a powered USB hub and then plug the USB hub into the Fire Cube. I did that to power a thumb drive that I attached that kept disconnecting.
