I was able to do initial install and connected to my home WiFi. I installed VScode. On day 2, the Spark can no longer connect to any WiFI with Setings/Wi-Fi delivering “No Wi-FI Adapter Found” message. Any guidance will be greatly appreciated.
I found the answer on StackExchange for this general Ubuntu wifi adapter missing problem.
get kernel version and reinstall, then restart
uname -r
6.11.0-1016-nvidia
sudo apt update
sudo apt install –reinstall linux-generic
sudo apt install linux-modules-extra-6.11.0-1016-nvidia
( restart and WiFi network adapter is there again )

Hi randyklingenberg, if the issue reoccurs, please capture and share the following details while it’s happening.
-
Output of “lspci”
-
Dmesg logs - sudo dmesg
Hi, my first day powering on DGX Spark. Wifi came up fine first and proceeded to update as instructed. After reboot, wifi disappears. It cannot get to copper Enet and no response when I connected RJ45. No funny business in between.
Here are the lspci and dmesg logs. Please help!!! It badly sucks to find DGX Spark incommunicado on first day.

@yoshenhou please post the output of lspci -k to see what drivers are in use. Also, please post the output of rfkill list
Looks like your network driver(s) don’t load. For the wireless mt7925e module is being used. If properly loaded during boot you should see entries like this in the dmesgoutput that are missing from yours:

Please try sudo modprobe mt7925e and post the output.
Here is the lspci -k log. And “rfkill list” returns nothing. Also modprobe says it cannot find the module.
Thanks. Somehow the device driver gets deleted during system update. Can you tell me where to get a copy of the device driver?
jhou@spark-7c20:~$ sudo modprobe mt7925e

And similarly, the 10GbE RJ45 on back of Spark cannot be enabled. Spark sees 4 network devices (enP2p1s and enp1s) and they are all “unplugged” when a 10GbE cable is connected. On farend, a Mellanox NIC sees the 10GbE connection. What network driver is being used for this RJ45 port? Is the driver also deleted? Is this RJ45 one of the 4 Enet port?
The 10G port is using r8127:
0007:01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. Device 8127 (rev 05)
Subsystem: Realtek Semiconductor Co., Ltd. Device 0123
Kernel driver in use: r8127
Kernel modules: r8127
and Connect-X is using mlx5_core
These are the files in /boot:

There are two kernel. Try booting with 6.11.0-1014 then finish the upgrade from the command line.
I didn’t run into the upgrade issue, so both kernels have the necessary drivers:
elsaco@spark:~$ find /lib/modules -name r8127.ko.*
/lib/modules/6.11.0-1014-nvidia/kernel/drivers/net/ethernet/realtek/r8127/r8127.ko.zst
/lib/modules/6.11.0-1016-nvidia/kernel/drivers/net/ethernet/realtek/r8127/r8127.ko.zst
elsaco@spark:~$ find /lib/modules -name mt7925e*
/lib/modules/6.11.0-1014-nvidia/kernel/drivers/net/wireless/mediatek/mt76/mt7925/mt7925e.ko.zst
/lib/modules/6.11.0-1016-nvidia/kernel/drivers/net/wireless/mediatek/mt76/mt7925/mt7925e.ko.zst
Find what kernel has both drivers and boot it. Look into /lib/modules/
