I am not able to fully set up my DGX Spark due to network connectivity issues. When it comes to the step where I have to choose the WiFi network, it always says “could not connect to the network”. I think Ethernet is not detected as well. (According to the docs if Ethernet was detected, it should not prompt for WiFi setup.)
Things I have tried,
different networks, hotspots - does not work.
In fact, I have two units of DGX Spark. The other unit is up and running with the same WiFi, Ethernet setup so the network itself should not be the problem.
Did the system recovery by flashing the OS again. I have tried two versions but neither is working.
However, I noticed that my (other) working DGX Spark is using the os VERSION=“1.81.38”. I was not able to find a download link for that version. I assume installing that version could work.
Any help is greatly appreciated!
PS: I already tried customer support, but they eventually directed me to this forum.
Yes initial startup hotspot works. I proceeded with that setup as well (i.e. network-based setup without connecting mouse/keyboard). Was able to connect to it from another PC, but still fails at the same step - the Wi-Fi connection step
didn’t know that, thank you. I just did cat /etc/fastos-release to get the version in the working unit.
Be aware if you are using the newest version of the Nvidia Sync app there may be a bug that is causing the Sparks to keeping reassigning themselves new hostnames every 20 seconds. I am having the same problems and it looks like the Nvidia sync app is the culprit, but I am still investigating. If you quit the Nvidia Sync app and reboot your sparks - if they were setup far enough you should be able to ssh into them again manually (don’t use Nvidia Sync).
When I know more I will try to post a more comprehensive write up.
update: after trying multiple attempts I was able to configure it using a mobile hotspot. (Just putting this here in case some encountered the same problem.)
For some reason it was not connecting to the same WiFi network where there was an already connected (another) DGX Spark. After setting up the second Spark using the hotspot eventually it was able to connect to the same WiFi network as the other DGX Spark. Ethernet is also working now : ). Maybe this is related to what @west4 , or maybe not.
We have seen reports of units not syncing their internal time correctly which results in not being able to succesfully connect to ethernet or wifi. Since you can access the UEFI menu, I would suggest trying to set the time manually and seeing if that helps.
