UGREENEthernet 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.

My rule of thumb is that you should always wire your stationary devices to Ethernet, whenever possible. I've spent way too much time in my life troubleshooting issues that were the result of how limited WiFi can be. If you live in an apartment, townhouse, etc. then this adapter is probably for you. If you care about your TV streaming stick/box to "just work", then this adapter is probably for you.So far, I've now used this Ethernet adapter on my Roku Express 4K+ and now on my Walmart brand "onn. Google TV 4K Streaming Box" (2023). The latter proved to be tricky due to how sensitive the onn. box is with micro USB cables, OTG power cable splitters, and USB Ethernet adapters. While the onn. is a fantastic value, it will boot loop and/or crash (distorted screen and loud audio feedback) if you aren't careful with your cabling. I was almost ready to just return the onn. box back to Walmart until I decided to try out this adapter since it worked out so well on my Roku. The adapter did not disappoint again and played nicely with the onn. box and no extra setup was needed outside of plugging everything in. The unfortunate thing is cost, this adapter costs about $5 less than what I paid for the onn. box itself and you can only get 100Mbps maximum throughout (no fault of the manufacturer). That said, the reliability and consistency you get with Ethernet is worth it making this a great purchase. Also, the 100Mbps limit hasn't prevented me from watching any 4K (w/HDR) content either nor any other issues whatsoever.

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 got this to provide my 1st generation Chromecast with faster, more reliable ethernet access given that the Chromecast is installed just above my router. I wanted to power both this adapter and the Chromecast from the USB port on the TV. I was worried that the USB port might not deliver adequate power to run either or both devices. I used a USB power meter to see how much power I could pull from the TV's USB port while charging my phone and was able to see about 1.4 amps being delivered. I hoped that would be adequate and tried it all out. It works fine! Your mileage may vary. Easy to install and use. I know that some people complain that the cable length isn't enough but in my case it is too long, if anything and I have to coil up the extra cable to keep the rat's nest in my entertainment area orderly.Added -> I like the one I got for my video Chromecast so much, I got one for my audio Chromecast as well.

Works fine with Roku Express 4K+. Connected itself instantly after making all of the connections.

Was very skeptical about buying this product because I have had bad luck with this specific brand before but to my surprise it works flawlessly. I was originally going to get an OTG usb-a to micro usb cable and a gig usb Ethernet adapter but I took a gamble on this instead. Yes it’s only 100mbps but I was barely getting 20mbps via WiFi and it would cut in and out. It’s all sturdy plastic and it’s a sufficient length for my use case. I also appreciate the link/status lights on it so you know you’re getting signal. Not all adapters have this. Now I have a permanent hardwired connection to my Firestick and no more connection issues. I don’t really need the gig adapter for just streaming as I don’t run a plex server or anything that would demand a higher bit rate so the 100mbps (actually caps out at about 90-95) is just fine and I don’t eat up unnecessary bandwidth needed for my laptop or PS5, both of which are hardwired via a gig switch. I did have a couple minutes when I first connected it that I didn’t think it was going to work at all but I just restarted the Firestick and bing bang boom it was recognized. I would recommend this if you don’t need the extra bandwidth (kodi, plex, bluray rips, etc) and even then you will be limited to 480mbps due to the usb2.0 transfer rate limitation on the Firesticks micro USB port. I always hardwire my devices when possible and I’m glad this worked out.

Works with Firestick but not with Roku devices. Will keep it just for the Firestick.

What a difference in speed between Ethernet & WiFi. Purchased this to prevent delay. Very easy to connect & not bad in price for it. The wire length is the same as the power cord that comes with it. Used on a firestick & worked well
