DGX Spark isn't working

I recently received a new DGX Spark and have encountered multiple critical hardware failures that make the system completely unusable. I’m reaching out to see if others have experienced similar issues and to seek guidance on next steps.

Issues Encountered

1. Complete Network Connectivity Failure

•Wi-Fi: Non-functional

•Bluetooth: Non-functional

•Ethernet (wired): Initially showed NO-CARRIER status across all ports

•Hardware is detected (lspci shows MEDIATEK Corp. Device 7925), but drivers appear to be missing or non-functional

2. Unresponsive System/UI

•Login screen frequently becomes completely unresponsive

•The pre-populated username button on the login screen is non-functional

•Workaround: Must click “Not listed?” and manually enter credentials each time

•System requires frequent reboots just to attempt basic operations

3. Thermal Management Failures

When running sudo dmesg | grep -i “firmware”, the logs show repeated thermal errors:

Plain Text

ACPI: thermal: [Firmware Bug]: No valid trip points!

4. Additional Non-Functional Features

•Sound/audio output

•Bluetooth peripherals (keyboard, mouse)

•Basic input device connectivity

Diagnostic Steps Taken

1.Ran rfkill list all - returned no output (wireless devices not recognized by kernel)

2.Ran lspci - confirmed hardware is physically present

3.Ran dmesg | grep -i “firmware” - revealed thermal firmware bugs

4.Attempted wired Ethernet connection - eventually got physical link but DNS resolution failed

5.Attempted system updates via sudo apt update - failed due to DNS issues

Current Status

The system is essentially unusable for any AI development work. Even after connecting via Ethernet cable and getting a physical link, the system cannot resolve DNS queries, preventing any software updates or fixes.

Questions for the Community

1.Has anyone else experienced similar issues with a new DGX Spark?

2.Are there known firmware or driver issues with the MediaTek wireless hardware?

3.Is this a quality control issue with a specific batch, or an isolated defect?

4.What is the recommended path forward - RMA/return, or are there recovery procedures?

I’ve seen many positive experiences shared in this community, which makes me wonder if this is an isolated defective unit or part of a broader issue.

Any guidance from NVIDIA support or community members who have faced similar issues would be greatly appreciated.

System Information

•Product: NVIDIA DGX Spark

•OS: DGX OS (Ubuntu-based)

•Wireless Hardware: MEDIATEK Corp. Device 7925

•Status: Out-of-box, first boot

Thank you for any assistance you can provide.

best to download the DGX Sync: Try NVIDIA NIM APIs

once you have at the top you should see an icon that provides ways to connect. Inital support it will ask for you to pair DGX to your device. From this point i noticed i dont see it in my bluetooth or wifi anymore, but i don’t need it since DGX sync serves as the port connection to the device via network.

Hi Regantih,

Sorry to hear about your DGX Spark experience. If you’re using a Spark FE unit, please contact my colleagues at NVIDIA DGX Spark Support . They can help run diagnostics and review replacement options if needed.

Regarding the ACPI: thermal: [Firmware Bug]: No valid trip points! messages: Our software stack doesn’t rely on that ACPI feature, so the log entries can be safely ignored. We’re planning to make this clearer in future releases.
