- Reviewed in Canada on January 28, 2025Verified PurchaseI purchased this adapter to convert my Roku Express (2023) HD model 3960CA to a wired version and it works perfectly. I have no complaints and would recommend this adapter.
- Reviewed in Canada on May 21, 2017Verified PurchaseI was skeptical by getting the off-brand Ethernet adapter for the Chromecast (there is a pricier version available directly from Google) but it works wonderfully. I've only used it for roughly 2 weeks, so not very long. I can't yet speak to long term quality - like if the internals will eventually corrode themselves away from the inside out, much like no-name cheap iPhone wires sometimes don't last long - but this device is a beauty and works completely as advertised!
No set-up is required, you simply plug the the connections into what's required and the Chromecast will immediately switch to Ethernet and no longer use the wifi connection is had in it's memory. For this this means I can now stream 1080P much more smoothly and it has greatly improved my viewing experience.
It came with a mini-CD. I have no idea what the content of it was - presumably instructions? Although it doesn't need instructions as you simply connect the 3 wires (one to power source, one to internet, and one to the Chromecast) and it works from there on out. I don't have an optical drive in my computer so I'll never know.
- Reviewed in Canada on March 13, 2025Verified PurchaseWorks perfectly with my Roku Express 4K 2021. I had another Ethernet micro USB adapter before this one, but my Roku Express has stopped working with it ("not enough power" error) after a software update sometime in 2024.
- Reviewed in Canada on October 22, 2020Verified PurchaseThis really was simple to setup. I followed the other reviews advice and reset my Chromecast first. Once complete, I unplugged it and switched it over to the Ethernet and turned it back on. That’s it - no messing around with Wi-Fi.
After running a few tests the ping is reduced and loading content is faster. Once streaming there’s no difference for me as my Wi-Fi was decent however this product really does improve latency. Feels snappier.
I took away one star because it takes a little more amps than expected so had to use a different USB port or the chromecast rebooted due to insufficient power. Also, the cables are a little long for my taste. Overall it’s good quality though.
- Reviewed in Canada on January 6, 2025Verified PurchaseWorks as advertised!
- Reviewed in Canada on January 28, 2024Verified PurchaseChromecast is USB C, this adapter is micro usb.
- Reviewed in Canada on May 29, 2024Verified PurchasePurchased to connect my Chromecast to internet directly. Did not work for my needs as Chromecast needs a specific plug directly from Google. Easy return
- Reviewed in Canada on February 23, 2022Verified PurchasePrior to using Ethernet adapter, my Chromecast was connected to my network via wifi. When streaming shows the picture would pause every 10 minutes or so and then take at least 30 or more seconds to resume. Connecting this directly to the wifi router via Ethernet has solved the issue. Once the show starts it plays right through to the end now without any pauses. Connecting this was very simple to do. The key thing to remember is to do a factory reset on the Chromecast after you have connected it via Ethernet and follow the normal setup process.

5.0 out of 5 stars Green ethernet adapter
Verified PurchaseGreat product and sturdy easy to install and cables are long which is nice to see. I know it states on up to 100mbps but it basically shows 97mbps on mine and I get 150mbps. But all is great works great and I'm happy with it.

5.0 out of 5 stars Ottimo per chromecast 2
Verified PurchaseSemplice da installare, basta inserire nel cavo ethernet, la usb alla spina ( io l'ho messo nell'alloggio del tv) e la micro usb inserirla alla chromecast. Dopo pochi secondi lampeggiano i LED e la chromecast è collegata. Per controllare basta entrare nel software del router e verificare che sia collegata su cavo LAN, da questo momento non si collegherà più in wifi ma solo via cavo automaticamente.
Velocità 100 mbps come dichiarato, controllato con speed cast.

5.0 out of 5 stars Works on firestick out of the box
Verified PurchaseGood build quality and does exactly what it is supposed to do. Provide an ethernet connection between router and firestick.
This allows the firestick to operate on a wired connection to the internet. No need to rely on a noisy Wi-Fi environment
