Belkertech Fire TV Ethernet Adapter, Belker Fire Stick Ethernet Adapter/Micro USB to Rj45 Ethernet Adapter, USB to Rj45 Cable for Fire TV Stick (2ND Gen), All-New Fire TV (2017), Chromecast Ultra/2/1/Audio Etc

I was a bit hesitant purchasing this based on the previous two iffy (fake?) reviews and the "customer" questions which had a similar pattern of incorrect English grammar. And why would both previous reviews state "It saved my gadgets"? Didn't make sense to me. Very odd I thought. Anyway, I pulled the trigger since it was $3 cheaper than the Amazon branded ethernet adapter. The small box it arrived in was in terrible condition, almost open, with no tape at all to secure it during transport. Really sloppy, I thought. Thankfully the actual product was in a small bag and looked new. The adapter I received has no branding on it at all, unlike the pictures which show "Belker". Even the box that it came with only had a crooked Belker sticker on it which could be removed. But after plugging it into my Fire TV 3 (4K), it worked right off the bat. I was having intermittent disconnects with my FTV3 in my home's very stable mesh wifi network (the FTV3 was the only gadget that did this; I tried 2 different ones and same behavior). When I sometimes woke it from sleep, I annoyingly had to re-enter our long wifi password each time. Thankfully, with this "Belker" adapter, the FTV3 is now wired and no more disconnects are occuring. I'm getting 94mbps down using an old CAT5 cable (this is NOT a gigabit adapter after all). So, 5 stars for now since it works as advertised. Let's hope it lasts.

5/6/2020 Just finished the setup and its not letting me put up a picture but went from 4mbs(wifi) download to 80mbs...my router is right next to the TV. I bought two. They both worked. Both 80mbs download. I am using a switch. It seems to be working like a champ. I also used it on chrome and firestick. Fire stick was weird that I had to go to network setting to hit play. (If you click select it had me put in a ip address but just click play). Chromecast restarted a couple times first but other than that no setup issues. I did have it on my wifi connected to my phone first. So idk how well it will work if you just start from scratch.

Works really good exactly what I needed

I bought this on the recommendation of the folks at Roku for a Roku Express 4K+. The connections were easy to make and the device has long(er than most) cables that make this convenient to use. Plug this device into the Roku in place of the power cable that comes with the Roku and connect an ethernet cable to our router or switch and plug in the power brick that came with the Roku. Boom, instant connectivity to your wired network. I did not have to make any adjustments on the Roku device, it recognized it was attached to a wired network and used that instead of wifi. I bought a second one to make another TV with a FireTV stick connect to the wired network and the experience was the same - it works great. Super happy with this device. Like most of these devices that actually work with Roku/FireTV, they are limited to 100Mbps, not 1000Mbps like most ethernet devices. i have never found this to be an issue (so far). I would have given it 5 stars but the device has no indicator lights on it showing power or ethernet connectivity. While I don't need that to determine if the device is working, it would be nice to see at least an indicator that the device was connected to power. I'd have given it a 4.5 rating but we don't have that here :)

Going from wireless to wired ethernet makes navigation in the apps much smoother. Scrolling/browsing videos in Youtube and Hulu is quicker. The Max app still has some lag, but it's much more responsive. I just got it, so I can't speak for it's longevity. I hope it lasts. I just plugged it in to my Roku Express 4k+ (3941) and it worked. The Roku disconnected from wireless and connected using the wired interface automatically. Note only certain models of Roku can use this adapter. Go to "support.roku.com" and look for a document titled "How to use USB to connect your Roku streaming device to a wired network" to see a table that shows which models can use this specific adapter. As of now, though similarly named, the "Roku Streaming Stick 4K" (3820) and "Roku Streaming Stick 4K+" (3821) are not supported by this adapter. Some Roku Streambar models can use an adapter, but not this one.

I like u can connect an ethernet cable to this for the firestick 4k tv it's hard to tell if it made it quicker for cutting load times but it almost seems the same I have a 400mb connection with comcast so it's very good and this is almost loading movies the same. But I think that's because this device limits the speed of the ethernet cable to a 100mbs which sucks that's probably why the loading feels the same. But it doesn't pause in the middle of watching a movie anymore to load so that's good. It does work but I wish it didn't cut the loading limit to 100mbs. But that's what I have to say about it. If there are better ones out there I'd get those instead

I went to the Roku website to get suggestions for a USB to RJ45 ethernet solution for my Streaming Stick 4K SKU#3820R. The Roku website had a link that took me to this product. First, the unit will directly connect to the Roku stick and provide power, but the stick has a separate Wi-Fi fob that also houses the sensor for the Roku remote. This unit does not allow for that part to be installed. So, yes the stick shows up on the HDMI port, but the remote does not work. There is no way, out of the box, to connect the two male-ended micro-USB plugs. I bought two female micro-USB to type A Male USB 2.0 adapters and a double ended female Type A USB 3.0 coupler. I hooked all that up and the Roku stick once again had power, but the remote would not work. The remote works fine if the RJ45 interface, and additional USB parts, are taken out of the equation and the Roku wi-fi/remote fob is connected directly to the Roku stick with the supplied Roku power block as directed in the Roku instructions. Yes, I did reset the Roku stick more than once with RJ45/USB config in place and verified the batteries in the remote were good. I realize that this listing does not say it works with Roku, but the Roku site take you to this listing so, I felt comfortable Roku knew what it was recommending. The fact that I had to buy additional parts may have been my first clue. Live and learn. This device may work with the Amazon Fire stick w/o issue. I did not test that. My 1 start rating is only because I could not get it to work with the specific hardware I have.

I was using the Amazon ethernet adapter, but it kept losing internet connection. Reviews say this is a common problem. This adapter seems to be working good. No drops. Max speed - 100mbps
