1000Mbps Ethernet Adapter for Chromecast with Google TV, USB Type C to RJ45 Gigabit Ethernet Adapter Compatible with Chromecast with Google TV HD/4K, Laptop, Tablet

Connects and works fine on Firestick 4K Max. I have 1 gig internet from VM and the speedtest app on my firestick shows just short of 400 Mbps dl, which is more than enough.

Doesn’t work at all. I’ve had it a few months but unopened and undamaged in anyway. Just tried fitting it and it just doesn’t work. Firestick not seeing Ethernet where everything else does so can only be that this doesn’t work. Too late to return as well!

Swapped out the Amazon Ethernet one that’s limited to 100MBs on the Firestick 4K Max and plugged this in. Now have 300MBs download speed. I did use a more powerful Quick charge plug as they recommended that you need more power. Well worth it.

This is working fine for me on Fire TV Stick 4K Max (2021 version), but as another reviewer mentioned, it is not recognised on the Fire TV Stick 4K (non-Max, 2018-2022 version), it will pass through USB power in both cases but the ethernet adapter is not recognised on the older 4K Stick. On the 4K Max I am getting 330Mbps on the speed test, a big improvement on the 90Mbps I achieved with Amazon's own USB ethernet 10/100Mbps adaptor. For an alternative product that works for me on both the old Fire TV Stick 4K (2018-2022) and the Fire TV Stick 4K Max (2021) - and hopefully later versions that I do not have available to test - there is the Cable Matters item . That one does work with similar 300Mbps+ performance, but does take a different approach to cabling - with a long built-in Y cable which replaces your original power cable with a USB A plug back to the PSU/charger instead of containing a micro USB-B socket to accept your original micro USB power cable. That might be considered tidier for some people or unwanted extra work for others.

Brilliant. Helps with wifi connection issues massively on the fire stick

Work as intented not like other brands. Managed to plug my Chromecast with Google tv (4k) and Ethernet was recognised. 🥳🥳

I bought this for use with my Chromecast with Google TV 4K. I have a Virgin Media connection of 1.1Gbps down and 110Mbps up. With this adapter connected to my CwGTV 4K I could only get 80Mbps down but was able to get the full 110Mbps up. I confirmed it is connected at 1000Mbps on the router and the link status LEDs also indicated a 1000Mbps connection. When I tested this with my Android phone I could only get 100Mbps down and 100Mbps up, this could be the faut of the phone though. However when I tested with a new Windows 11 laptop with a full speed USB C port, I get 930Mbps down and 110Mbps up. So it is not faulty, it just doesn't seem to work well with the Chromecast with Google TV which is its intended purpose. I will keep it was on special and I got it at a really good price for a RTL8153 adapter but its a pity it didn't get me more performance as I was expecting at least 400Mbps. I supposed if your Chromecast was getting less than 80Mbps over Wi-Fi you might get some benefit from this but not for me as my CwGTV gets 170Mbps over Wi-Fi.

Someone commented in reviews it will fit into an Amazon firestick. It doesnt. I thought they may be wrong when I read its description. But I chanced it. Don't buy for firestick, it won't fit. In the bin it goes.
