Wi-Fi tethering (iPhone) does not work on my AGX Orin of JETPACK 5.1.3

Hello

I reflashed my JETSON AGX Orin to JETPACK 5.1.3 recently but found that I can’t connect to Wi-Fi tethering of my iPhone.
After I input the password, there are no errors but it will ask me again after about 10 seconds. I tried several times but still not work. If I connect to Bluetooth, I can use sharing internet but it is too slow to use.
Of course, I can’t use USB tethering by iPhone so It is ok if USB tethering is available but I don’t know how to use it.
In the meanwhile, I tried to connect another Wi-Fi (not iPhone tethering but Wi-Fi router), it is working well.
Before this reflash, I installed JETPACK 6.0DP to this device and wifi thethering worked well on 6.0DP.

May I ask what is the reason for this issue?

Hello,

Welcome to the NVIDIA Developer forums! Your topic will be best served in the Jetson category.

I will move this post over for visibility.

Cheers,

Hi,
Please share the dmesg for reference. The log should be similar to
Android USB tethering not working - #10 by DaneLLL

I tried to connect to my iphone tethering via Wi-Fi just now and it failed. Then I tried to connect via Bluetooth and it worked.
Below is the latest message by command: sudo dmesg -T, is it right or is the information enough?

Hi,

You need to enable the following kernel config:

CONFIG_USB_NET_RNDIS_HOST
CONFIG_USB_IPHETH

to make USB tethering with iPhone work.
We will see if we can by default enable these configs to you don’t need to rebuild the kernel.

Some userspace tools are also required, like usbmuxd ipheth-utils libimobiledevice-utils.

Hi

Thank you for you information.
Exactly some other people also said that these tools are required.

I installed these tools but I don’t know how to enable the 2 kernel config.
If is works, can you share how to do here?
Thank you very much.

About Wi-Fi tethering, it connected sucessfully when I unchecked the box of [connect automatically] and [Make available to other users] in detail setting. I don’t know why it cause to fail to connect Wi-Fi, but for your information.

This is the update defconfig with required settings enabled:
defconfig (30.4 KB)
Replace the same file under Linux_for_Tegra/source/kernel/kernel-jammy-src/arch/arm64 with this copy, and build kernel again following our documents:
https://docs.nvidia.com/jetson/archives/r36.2/DeveloperGuide/SD/Kernel/KernelCustomization.html#building-the-jetson-linux-kernel
