Intel AC 8265 can't work well on my Jetson AGX Xavier

I just install an Intel 8265 on Xavier, and enable Wi-Fi, but I don’t see any available Wi-Fi in the Wi-Fi list as it should be. So I try to follow other topics, but still not working.I also try connecting to hidden Wi-Fi network by enter Wi-Fi’s name and password, just failed too. Follows are my configuration and details about my Xavier.

I followed this topic https://forums.developer.nvidia.com/t/intel-dual-band-wireless-ac-8265-on-xavier-solved/65464/24 to install linux-firmware and reboot, but it didn’t work.

-----------------------------Update on 5th, Aug--------------------------------
Firstly, I use backport-iwlwifi-dkms installed with apt:

$ sudo add-apt-repository ppa:canonical-hwe-team/backport-iwlwifi
$ sudo apt-get update
$ sudo apt-get install backport-iwlwifi-dkms
$ reboot

But I note a error while installing:

…
DKMS: install completed.
Building initial module for 5.2.0-050200-generic
ERROR (dkms apport): kernel package linux-headers-5.2.0-050200-generic is not supported
Error! Bad return status for module build on kernel: 5.2.0-050200-generic (aarch64)
Consult /var/lib/dkms/backport-iwlwifi/8324/build/make.log for more information.

I guess it means my Xavier kernel version not fit the backport-iwlwifi-dkms，So I Manually Backport the Iwlwifi Driver for older Linux Kernels later:
https://support.killernetworking.com/knowledge-base/killer-ax1650-in-debian-ubuntu-16-04/.
Still not work.

The full version of dmesg show in the dmesg.txt (78.8 KB) .

Any suggestion will be appreciated!

Sorry for the late reply, is this still an issue to support?
Any current status can be shared?

Thanks

@850565178

It works fine on my xavier devkit without any changes with JetPack.
Pls try to connect to a hotspot to see what happened.

sudo nmcli dev wifi connect "wifi-name" password "*****"

Sorry for the late reply. My problem was caused by the lack of the antenna.It solved itself after installing the antenna.
