Lose WiFi modules of Jetson AGX Orin

[Maik2008]

Hello,

but i found there is no wi-fi option. The setting is like that:

After that, i used the folled code:

sudo apt-get update

Q: Is there any example of running RTSP streaming?
Q: Is there an example for running UDP streaming?

Hello,

thanks for the link. I have noticed that they have downloaded a backport from Linux Backports. As i’m using 5.15.148-rt-tegra kernel, i choosed backports-5.15.148-1.tar.xz. then i uesd these code from this link:

tar Jxfv backports-5.15.148-1.tar.xz.
cd backports-5.15.148-1
make defconfig-iwlwifi
make -j8
sudo make install

and

I add the following line to /etc/modprobe.d/iwlwifi.conf

options iwlwifi 11n_disable=1

and , reboot OS.
But the wifi option still doesn’t appear.

By a way, when i input: lspci, there is

0001:00:00.0 PCI bridge: NVIDIA Corporation Device 229e (rev a1)
0001:01:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8822CE 802.11ac PCIe Wireless Network Adapter
0004:00:00.0 PCI bridge: NVIDIA Corporation Device 229c (rev a1)
0004:01:00.0 Non-Volatile memory controller: Silicon Motion, Inc. SM2263EN/SM2263XT SSD Controller (rev 03)

Does it means that the network card hardware is recognized by the system, but the driver may not be loaded or configured correctly?

Thanks!
