Jetson Orin WIFI&Lan module disappeared after rt_kernel built

Hi all,
I followed instructions on KernelCustomization(r35.1) and successfully installed the rt-kernel after reboot. However, I cannot connect to either the Wifi or Lan now.
I realized the above page do not match my release, so I inspected KernelCustomization(r36.4) and found nvidia-l4t-rt-kernel-oot-modules nvidia-l4t-display-rt-kernel missing.
I downloaded the following two files offline, installed it on the Orin, and then rebooted. But It didn’t solve the network problem.

nvidia-l4t-kernel-oot-modules_5.15.148-tegra-36.4.3-20250107174145_arm64.deb
nvidia-l4t-display-kernel_5.15.148-tegra-36.4.3-20250107174145_arm64.deb

The Network GUI:

The system info:

dmesg returns:
temp.txt (45.4 KB)

Hi,
If the device cannot be flashed/booted, please refer to the page to get uart log from the device:
Jetson/General debug - eLinux.org
And get logs of host PC and Jetson device for reference. If you are using custom board, you can compare uart log of developer kit and custom board to get more information.
Also please check FAQs:
Jetson AGX Orin FAQ
If possible, we would suggest follow quick start in developer guide to re-flash the system:
Quick Start — NVIDIA Jetson Linux Developer Guide 1 documentation
And see if the issue still persists on a clean-flashed system.
Thanks!

Those 2 deb packages you downloaded are not for rt version. Installing them does not help.

Also, I am not sure why a r35.1 document is still present here. This should be not referred to anymore. You should follow the r36.4 document for the whole steps.

You are right. I finally solved it by first
sudo apt remove nvidia-l4t-rt-kernel nvidia-l4t-rt-kernel-headers to go back to the normal kernel & reboot. Then sudo apt install nvidia-l4t-rt-kernel nvidia-l4t-rt-kernel-headers nvidia-l4t-rt-kernel-oot-modules nvidia-l4t-display-rt-kernel again.
Thanks for the help!
