If you are not aware of it, Google quietly released the $15 Ethernet adapter for Chromecast early this month. You can get it from Google devices store for $15.
This guide will show you how to use Ethernet adapter for Chromecast to get best connections for your Chromecast.
The Ethernet adapter is a lifesaver for those Chromecast owners:
In the box, you can find:
Ethernet cable is NOT included. As the Ethernet adapter for Chromecast does not offer Gigabit connection (it is 10/100M only), you should not worry about the category of the Ethernet cable. Old or new Ethernet cable should work.
The packaging is solid, but not friendly to users.
There are no configurations needed for Ethernet adapter for Chromecast.
Just plug and play.
To use Ethernet adapter for Chromecast, you may follow these steps (as shown in the picture below).
The sequence of these steps actually is NOT important.
You need make sure the Micro USB connector is inserted tightly into your Chromecast.
Both ends of any Ethernet cables should be identical. So, you just need make sure one end of the cable is inserted into the adapter and the other end into your router.
Most Ethernet cables have clips in both ends. When you want to unplug the cable, you should press down the clip and unplug it simultaneously.
Do not pull the cable forcefully without pressing down the clip. You may damage the Ethernet port.
Please follow the setup guide if you need use the HDMI extender.
Yes, Chromecast will fail over automatically to wireless connection when Ethernet is not available,
If you have setup your Chromecast with WiFi connection, your Chromecast can now use both Ethernet connection and WiFi connection.
When both Ethernet connection and WiFi connection are available, Chromecast will use Ethernet connection, not the WiFi connection.
When Ethernet connection is not available, Chromecast will use WiFi connection automatically.

I am a bit confused about the usefulness of this adapter. I have Chromecast working on one TV in my house with my Nexus 7 running Chrome Cast app and it works fine because it is close to my WiFi router source. When I go to a remote room that does not have adequate Wifi coverage I tried setting up a local wifi access point with a pld WRT54g router set into access point mode. I get 21 mbps wifi on this router. I tried connecting the chromecast and my nexus 7 to this wireless access point but when I cast the Nexus 7 the video is choppy and quality is bad. When I run the Nexus 7 alone (no casting) the streaming video on the device is fine - so I believe the WRT54 is fast enough to stream video over, but when I cast the screen, the video is not good. I think there is not enough bandwidth in the WRT54 to stream media and cast the Nexus 7 screen at the same time. Do you think that is correct? One solution I thought about was using the Chromecast ethernet adapter...but if I connect the Chromcast to hardwired ethernet, I still need to stream video using the Nexus 7 and cast the screen, correct? If I still need the Nexus 7 to cast the video to the Chromecast, I need the wifi network and since the ethernet is plugged into the Chromecast, I can't run the WRT54 as an access point anymore since that requires the ethernet connection also. So, with no WiFi - the Nexus 7 cannot stream to the Chromecast. How can I run a Chromecast device in a room with 1 ethernet wire connection and a Nexus 7 that requires wifi? Does the Nexus 7 actually access the Chromecast device through Wifi, to the router, then out the ethernet connection in the back of the router to Chromecast? Lots of questions I know, but as I said - I am confused. Thanks
Yes, the Ethernet adapter should help a lot. But if you need use WiFi and Chromecast in that room often, my recommendation would be a better router, not the Ethernet adapter. It is probably the best investment to enjoy your tablet and other devices.
Chromecast may not be as capable as nexus 7 for handling WiFi network connection, especially for the first gen of Chromecast. Nexus 7 may get almost the full speed that the router can offer. Chromecast first gen may not through WiFi (but it may get better connection through Ethernet adapter). This probably explains that you can play the video smoothly on the tablet, but not through Chromecast. The second gen of Chromecast performs far better, especially in 5GHZ.
In addition, you may get a cheap switch that essentially splits one port into 4 or more. You can use one port for the old WiFi router, one for the Ethernet adapter. In this case, you need set your WiFi router as bridging, not access point. In this case, you are only limited by the main router, not the old router.
thank you for your reply. I appreciate your help
I plan to use the ethernet adapter with my Chromecast Audio to get a solid data connection. I have one question. When the ethernet adapter is plugged in, does the wireless radio of the Chromecast Audio turn off? The reason why I ask is the hope of less interference to the optical signal from the Chromecast Audio to my DAC.
No, as I know. The wireless radio will not be turned off. But it will not try to connect to any routers. The interference should be very marginal.
