Issues with Intel 9620 WiFi Card/no wlan0 detected

Autonomous Machines Jetson & Embedded Systems Jetson AGX Xavier

Hello everyone,

i want to upgrade my NVIDIA Jetson AGX Xavier with an Intel 9620 WiFi Card, but it doesn’t work.
I’m looking for hours in so many forums, but don’t get a solution.
My basic problem is, that I can’t find wlan0.
iwconfig shows my only the devices: docker0, eth0, dumm0 and lo, but no wlan0.

The necessary driver is at the correct place in /lib/firmware.
Using the command lspci detects the wireless AC 9620 as a network controller, so the card works.

I guess, that something with booting isn’t correct, because every time the system starts, i get
‘Failed to start NVIDIA bluetooth/wifi init script’, but I don’t know what to do.

Thanks for yout help.

Could you share your log which captured with dmesg?

Let’s see what happened during the setup. Also pls share the details about the failed log about the NVIDIA bluetooth/wifi init script service.

Hello alanz,

here is the result of dmesg.
Do you need some more information?

From the log, I don’t find some abvious PCI errors except

[    7.292313] Loading modules backported from iwlwifi

And I also can’t find a working firmware/driver exactly matching with intel 9620.
Could you double confirm the driver you are trying with?

We have only verified the Intel 8265NGW on Xavier. It’s another choice may worth for you to have a try.

I see, I made a mistake in my question. It’s the WiFi Card Intel 9260, NOT 9620.

Anyway
It should be the driver iwlwifi-9260-th-b0-jf-b0-34.ucode (Linux* Unterstützung für Intel® Wireless-Adapter). The driver is located in /lib/firmware.

Do the jetson support this WiFi-Card?

Hi, @fabio.minx

I’m trying to have an Intel 9260 for verification. May need sometime.

Will feedback asap.

@fabio.minx

Intel 9260 provide the default driver for kernel 4.14+ as default. For jetson, the kernel version 4.9 need driver backport.
You can get the right backport driver here: kernel/git/iwlwifi/backport-iwlwifi.git - Backport tree for iwlwifi
