Cable MattersMicro USB to Ethernet Adapter Up to 480Mbps, Fire Stick Ethernet Adapter, Compatible with Fire TV Stick, Chromecast (Gen 1-3, up to Aug 2020), Google Home Mini – Not Compatible with Roku

Total game charger. Faster speedy on firestick 4k. Minimal buffering.

Super easy to setup, just replaced the Fire Stick's USB power cable with this adapter, plugged in the ethernet, and the FireTV Stick 4K Max (2nd Gen) is running on wired at ~450Mbps! =)I've got a solid WiFi5 speed from the Stick and it's been fine for streaming, but I'm now using the Stick for Xbox Cloud and Steam Link gaming... my WiFi signal has far too much "noise" unfortunately, and it's noticeable when gaming.This adapter solves that entirely, and now those options are running perfectly!Using it with a 2024 FireTV Stick 4K Max 2nd Gen and it was compatible instantly.

110% happy and more than satisfied with this adapter. Basically every other ethernet adapter made for use with the FireStick uses fast ethernet which limits you to a max speed of 100/100 Mbps even when they advertise speeds of up to 480Mbps (the max speed for the USB port on all Fire Stick and Fire Stick 4k models)--which is just plain dumb. However this adapter ACTUALLY has a gigabit ethernet port that allows you to break the hard 100Mbps cap every other adapter I tried was limited to . If you're only streaming Netflix or Prime Video 100Mbps is plenty, but I mostly use my FireStick to play stuff from my Plex Server in which case speed quickly becomes an issue when watching Blu-ray REMUX movie rips where the file size can be up to 50GB per movie. And even though the FireStick's Wifi speeds easily break the 100Mbps limit on most ethernet adapters, there's just too much lag and buffering over wifi to make watching those kinds of files semi-bearable.Then I stumbled upon this adapter and my prayers were finally answered. As can see in the screenshot I took using a network speed test app on my FireStick 4k , with this adapter I consistently get download speeds of 300-350 Mbps and uploads speeds of 250-280 Mbps (I have Fios gigabit ethernet) which is amazing. Now there isn't more than a split second of buffering at the very beginning with any movie/videos I watch, even massive blu-ray movie rips. It worked so well I ended up buying additional adapters for every FireStick in my house plus a few for my parents' Fire Sticks. It's been about 4 months now since I bought them too without any issues so I feel confident saying the quality of the product matches the excellent performance.(Note: if you're wondering why the speed isn't closer to 1000Mbps since the adapter uses a gigabit port, the reason is all FireStick models use USB 2.0 ports for power/wired network connections and USB 2.0 has a max speed of 480 Mbps, which is usually much lower when it comes to real world use--typically you can expect speeds of ~250-300 Mbps or lower for most USB 2.0 devices, at best made 375-400 Mbps if you're lucky.)

If you get an authentic Cable Matters cable, it does exactly what it needs to do.I was originally using the Amazon Firestick Ethernet adapter before realizing that it could only connect at 100 mbps max, which is kinda of pointless for a hard lined connection. This Cable Matters cable uses a gigabit Ethernet port to maximize the speed of the hard lined connection (limited though by the micro USB connection on the Firestick so you will only see about 400mbps) still way better than 100 mbps that you would get with the Amazon adapter.I used this for a Firestick with power plugged in at one end of the adapter and Ethernet plugged in at the other. I also used this with a FireTV Cube with just the Ethernet plugged in. (FireTV Cube has it's own power connection). Both configurations work great.Product is 5 star but Amazon needs to watch out for fakes. I originally received 2 boxes, 1 was authentic but the other was unbranded and looked different. Boxes were identical. The unbranded cable actually did not even work, my Firestick would be stuck in a bootloop. You can see from the pictures that the authentic Cable has "Cable Matters" imprinted on the housing.

WORKS GOOD

I have my garage set up like a sports bar with 5 TVs and various devices using the internet for streaming sports. I was getting intermittent buffering using the wifi connection for Amazon Fire Stick 4K Max. I decided to run an ethernet to the garage and install an 8-port ethernet switch. Bought this to connect to the Amazon Firestick. Specifically chose this one, since one of the few if not only that can go over 100Mbps which includes the official Amazon one. After connecting the wires, the Amazon Fire Stick automatically connected to the ethernet. The speed test shows close to 200 Mbps with that speed probably being the limit for the firestick. As a result, no longer do I have buffering. Highly recommend this device to connect to FireStick via ethernet.

Many of today's laptops, including my new HP EliteBook x360, don't have an Ethernet port, as if the world has moved on from Ethernet. Well, for those times when you want or need to connect directly to a switch or cable modem for speeds WAY faster than WiFi, or you have some other networking need, this works reliably, quickly and without set-up. I have bought two now, because I gave one to an engineer who needed it in a pinch and he was so happy with it, I didn't have the heart to take it back from him ;-) Gotta keep your engineers happy...

I purchased this item to get the most bandwidth possible out of my internet connection to my Fire TV cube for streaming. This was easy to set up and immediately went from 90mbps to over 300mbps which was great. This was A LOT faster than the standard adapter that came with the Fire TV Cube if you wanted a wired connection.However, two months later and my speed dropped in an instant to 8mbps. All of my other devices were hitting speeds at 400mbps except the Fire TV. I switched out the cable back to the one provided with my device and I am back to the 90mbps I used to have before purchasing this adapter. Disappointed.So buyer beware. Mine only lasted two months. What a shame.
