The Ethernet cable was connected to GB10 , and then power on the device ,whereas prompt to Select your Wi-Fi network and no wire ethernet was shown .
I confirmed that there were no issues with the Ethernet cable or the wired network itself. Are there any special requirements for connecting to the wired network? Such as enable the DHCP server?
Are you setting it up as a network appliance or desktop?
A fast, reliable internet connection (Wi-Fi or Ethernet) to download required updates during the initial setup process. Connections using captive portals (such as hotel or airport Wi-Fi) or those prone to disconnections (like phone hotspots) are not recommended. If you do not have access to a stable connection, consider downloading the system recovery media and using System Recovery to install the latest software for your DGX Spark.
For Local Setup: A display, keyboard, and mouse connected (or available using Bluetooth).
For Network Setup: A computer on the same network to access the setup interface.
Power connected to the system (the system will start automatically when power is applied).
There may be an issue where your unit’s time is not syncing properly. Please try powering off your device, plug out the power cable, plug in the ethernet cable, power on the unit again and wait a few minutes before going through the setup process.
by any chance you happen to have another DGX Spark already connected to the same network? I had a similar experience where a second DGX Spark won’t connect to the same network (during initial setup). I had to use a different network (in my case a hotspot) for the initial setup. After the setup and updates it was able to connect to the same network.
