Jetpack 6 WiFi does not work with Intel AC 9260

[dakejahl]

I flashed my Jetson Orin NX with Jetpack 6 and the wifi card is detected and bluetooth works, but wifi does not. This card works out of the box with Jetpack 5.

I have seen this issue Cant access Wifi on Jetson Orin Nano running Jetpack 6 dev however the solution is not ideal, since I would then need to hook up ethernet to install backport-iwlwifi-dkms.

Hi,
Does it work if you apply the solution? Jetpack 6 release is more close to upstream kernel and certain configs may not be enabled by default. For this you would need to enable it manually.

[dakejahl]

Yes installing backport-iwlwifi-dkms fixes the issue. It would nice if this would be included in the kernel. This is a regression from jetpack 5 and requires hooking up an Ethernet cable after flashing. This wifi card is very popular and should be supported out of the box.

Hi,
By default we support the module:

0001:01:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8822CE 802.11ac PCIe Wireless Network Adapter

For using other module, please apply the manual step.
