I have a Nest Hub with Fuchsia with a USB to Ethernet adapter attached. Ethernet in this build is only partially functional, and Wi-Fi is required for the normal functionality to be available.
Ethernet worked properly prior to the Fuchsia update, this is a regression.
I would like either a) a resolution to this issue or b) a way to block updates on my other Nest Hubs (since Fuchsia will go to everyone eventually).
Version Information:
Broken (Fuchsia):
Working (Cast OS):
Google Home Android app version: 2.38.1.7
More Details:
As many here know, the Nest Hub smart display has a Micro-USB connector under the bottom plate. This connector can be used with certain USB to Ethernet adapters (and a Y-cable for power if needed) to connect the Nest Hub to an Ethernet network.
With the regular Cast OS (*pre-Fuchsia*), the adapters work very well. The Nest Hub recognizes that it is connected to Ethernet, and is not required to be connected to a Wi-Fi network during Setup. All functions just work.
I enrolled a Nest Hub that was working on Ethernet into the Preview program. The Nest Hub was upgraded to Fuchsia.
If you want to try it: The selection of Ethernet adapters is reduced from Cast OS.
The following works with Ethernet only (Wi-Fi not connected to AP):
Simultaneous Wi-Fi and Ethernet functions - the Fuchsia Nest Hub will pull an IP on each interface and respond to both. But the Cast OS Nest Hub would not even attempt to connect to Wi-Fi if Ethernet was detected, and that is the behavior I want.
The following does not work with Ethernet only (Wi-Fi not connected to AP):
Factory reset does not solve the problem either.

- Asix AX8877C and Asix AX88179 work as described in the following section. (AX8877B should also work.)
- AX8877A does *not* work (which did previously with Cast OS).
- As with the previous Cast OS (not a regression), Realtek 8152s do *not* work including the Google EA4CC-1A, even though the Fuchsia source tree lists usb-cdc-ecm.
The following works with Ethernet only (Wi-Fi not connected to AP):
- DHCP
- DNS (but, DNS query responses to the Nest Hub often get ICMP Port Unreachable as a reply from the Nest Hub.)
- Inbound and outbound TCP connections, including to the Internet
- Built-in webserver
- Casting - Yes, even while the Setup screen is showing on the device, you can cast to it over Ethernet, remotely control volume, etc.
Simultaneous Wi-Fi and Ethernet functions - the Fuchsia Nest Hub will pull an IP on each interface and respond to both. But the Cast OS Nest Hub would not even attempt to connect to Wi-Fi if Ethernet was detected, and that is the behavior I want.
The following does not work with Ethernet only (Wi-Fi not connected to AP):
- net.ethernet_connected in eureka_info is false (even though I queried eureka_info through Ethernet!)
- net.online in eureka_info is false (even though I can make it connect to Internet radio stations through Ethernet)
- Setup via Google Home app insists on Wi-Fi and will not let you skip
- Smart Display shows Setup Screen (the Wi-Fi animation + "Follow the Instructions in your Google Home App")
- Google Assistant - if you talk to it, you get a voice response complaining that it can't find the Wi-Fi network
Factory reset does not solve the problem either.
