UGREEN Ethernet Adapter for Fire TV Stick, Micro USB to Ethernet Adapter with 3.3 ft Cable & Power Cord, Compatible for Fire Stick Basic/2nd/4k/Lite, Chromecast 1/2/3/Ultra/Audio, Plug & Play, 100Mbps

I ran across this item as a result of reading articles about the certificate issue for some Chromecast sticks/discs. In a response in a forum someone said that Google had made Ethernet adapters but had discontinued them. I decided to search and see if someone else had filled that gap, and found this for an answer.You need two things that do not come in the box. An Ethernet cable and a USB-A socket for power.This is as simple as it gets. You plug it in. It works.I have a total of four Chromecast sticks/discs. I bought some extras when word went out that they were being discontinued. My Chromecast stick is a first-generation unit that I got for free with a cell phone. This is the unit I used for testing the adapter. The stick is working better than before. I still often get blurry video when it first starts up, but it clears up faster than before and further blurs happen less often. Broken connections happened now and then, not any more. These were problems I’ve had for years due to house structure and the impracticality of repositioning the router or the TV.I have ordered three more adapters for my disc units. I prefer wires to WiFi when possible.If you have need to wire up a supported device, this unit will do the job.I may not end up using them all, but I'd rather have and not need than need and not have.

Works great for the Roku Express 4k, despite what the description says about not being supported. It is automatically detected and used if an ethernet cable is plugged in. Max speed of 93Mbit, but still a lot better and more stable than 2.4ghz wifi speeds.

I ordered this --- Fire TV stick streaming media player, with Alexa Voice Remote (2nd Gen, released 2019) --- to add ethernet streaming to an old 19" LCD TV that has coax, component, composite, VGA and 2 HDMI inputs. This TV lives in the kitchen and is attached to via coax, and sits upon, an older cable TV box. Space is tight where the TV and cable box sit at the end of the counter.I wanted an installation as compact as possible, and, use ethernet. I didn't like the looks of the VERY short Amazon brand ethernet adapter for the Fire stick, and, since it has to be purchased separately anyway, I ordered this one at the same time, --- Price: $13.89 --- UGREEN Ethernet Adapter for Fire TV Stick (2nd GEN), All-New Fire TV (2017). It has a 3.3ft USB power cable & micro USB cable. I used the USB power supply that shipped with the Fire stick.I couldn`t have the Fire stick hanging out of one of the two HDMI ports on the TV, so I included one each of the following M x F ( 2 pcs ) extension/adapter cable sets, with my order ;* Price: $9.99 -- HDMI 2.0 Extension Cable, Cable Creation [2PCS] 1.5 Feet Upward Angle HDMI 2.0 Male to Female Cable + 1.5 Feet Downward Angle HDMI 2.0 Male to Female Cable, 4K Ultra HD, Black.---- And ----* Price: $9.99 -- HDMI 2.0 Extension Cable, Cable Creation [2PCS] 1.5 Feet Right Angle HDMI 2.0 Male to Female Cable + 1.5 Feet Left Angle HDMI 2.0 Male to Female Cable, 4K Ultra HD, Black.I figured one of these four ext./ adapter cables would give me the correct direction from the side or rear HDMI port to remote mount the Fire stick. The male end of the angled ext./ adapter cable is plugged into the side HDMI port, goes up the side and over the top. The 18" length was ideal for a Fire stick location on top of the TV, the Fire stick male end is plugged into the female end of the ext./ adapter cable. I attached the cables and the Fire stick to the top of the TV with some homemade twist ties, fished through the heat vent slots.I plugged the Cat5e cable into the modem and the other end into the Ugreen ethernet adapter, chose HDMI-2 on the TV input and plugged in the USB power supply. After the yellow and green lights came on at the Cat5e end of the ethernet adapter, the Fire stick powered up to the setup screen. The setup was straight forward and the Fire stick works very quickly, probably because of the ethernet connection. We have an early Fire TV box ( the flat one ), attached to our big TV via ethernet and it works quickly also.We subscribe to Amazon Prime and I enjoy listening to Amazon Music through a Creative sound card in the PC, then into a good mini amp, a pair of nice small speakers, along with a sub. This old kitchen TV has very poor speakers. t has a coaxial digital audio out connector that I hooked into a DAC then into an old pair of powered PC speakers, sound was much better, but I`d need to find a place in the kitchen for more equipment !

The great plus to this adapter is you are able to run a Ethernet cable to your fire tv. When I first tried doing a speedtest on the fire tv I could only get around 35mbps download speed. When I do a speedtest using wifi, I get around 53mbps download speed. To do a speedtest on your fire tv just download firefox and go to google search and type “speedtest”. I have 300mbps internet speed. I realize the Ethernet adapter will not allow you to get more then 100mbps but I can’t understand why I am getting 35mbps download speed. The upload speed seems to be okay. When I do a speed test with my computer it gets over 300mbps download speed with a Ethernet cable. I tried three different Ethernet cables(2 Cat 5e and 1 Cat 6) with the ugreen ethernet adapter and all the speeds were still around 35mbps. It seems like many other people are having the same issue but nobody knows why. My internet providers website says the top reason you could be experiencing slow downloads speeds is because of the hosting server. So its possible the problem could be on amazons server or it could be the processor on the fire tv. Other websites recommend to enable download QOS on your router, some say changing the MTU size on your router but nobody confirms that worked for them.Update 3-2-2018This most likely is the reason why some people are seeing slow internet speed readings.When doing the speedtest, you will get a slow internet speed from certain websites. I did a speedtest from four different websites. The only speedtest website that was accurate is xfinity speedtest website. This website showed me at 61mbps which would be the ballpark range a ethernet adapter can get. The other three websites showed me at 35mbps. The person I knew who was getting 61mbps, I asked him to try different speedtest websites and he said the other websites showed him at 40mbps. I guess it just depends on how busy a website server is. If the traffic is low, you will get a higher internet speed reading. If the traffic is high, you will get slow internet speed reading.
