JetPack 7.2 Wireless Module Setup Guide

After upgrading a Seeed Jetson device to JetPack 7.2, some users may find that the M.2 Key E Wi-Fi module is detected on PCIe but no wireless network interface appears.

This guide covers the JetPack 7.2 repair flow for the following modules:

Intel AX210 / AX200, using iwlwifi and iwlmvm.
Realtek RTL8852BE / 8852BE, using the rtw89 driver stack.

The fix usually requires two parts: installing the kernel modules that match JetPack 7.2 kernel 6.8.12-1021-tegra, and decompressing the corresponding firmware files under /lib/firmware.

note

This guide is intended for JetPack 7.2 systems using kernel 6.8.12-1021-tegra. The repair driver modules are built for this kernel. If uname -r shows a different kernel, use the driver package for that exact kernel version.

Symptoms

After upgrading to JetPack 7.2, you may see one or more of the following symptoms:

lspci can detect the Wi-Fi module, but ip link does not show wlan0.
dmesg reports iwlwifi or rtw89 firmware loading errors.
modprobe reports that the expected module cannot be found.
Loading the driver manually works temporarily, but Wi-Fi disappears again after reboot.

Prerequisites

A Seeed Jetson device flashed with JetPack 7.2.
Kernel version 6.8.12-1021-tegra.
A supported M.2 Key E Wi-Fi module installed correctly: Intel AX210, Intel AX200, or Realtek RTL8852BE.
Temporary Internet access through Ethernet, USB networking, or another network adapter.
sudo permission on the Jetson device.

Check the kernel version and PCIe device first:

uname -r
lspci -nnk | grep -A3 -i network

Common PCI IDs include:

Module	Example PCI ID
Intel AX210	`8086:2725`
Intel AX200	`8086:2723`
Realtek RTL8852BE	`10ec:b852`

Option 1: One-click Repair Script

Use this option if the Jetson can access the Internet through Ethernet or another network adapter.

The script downloads the repaired JetPack 7.2 driver modules from the public OneDrive folders, stores them under /tmp/jp72_wifi_fix/driver/, installs the selected module set to the current kernel module directory, decompresses the required firmware files, and enables automatic loading at boot.

tip

The OneDrive web link is not used directly as a curl download URL. The script first opens the shared OneDrive page to obtain an anonymous SharePoint cookie, then downloads each file through the SharePoint REST %24value endpoint.

Create the script:

cat <<'EOF' > fix_jp72_wifi.sh
#!/usr/bin/env bash
set -euo pipefail

usage() {
  cat <<'USAGE'
Usage:
  bash fix_jp72_wifi.sh [--ax210|--ax200|--8852be|--download-only]

Options:
  --ax210          Install Intel AX210 iwlwifi modules and firmware.
  --ax200          Install Intel AX200 iwlwifi modules and firmware.
  --8852be         Install Realtek RTL8852BE rtw89 modules and firmware.
  --download-only  Only download selected driver modules and print the local file tree.

Option 2: Manual Setup

Use this option if you prefer to download and install the files manually.

Intel AX210 / AX200

Download the JetPack 7.2 Intel driver package from the OneDrive folder below:

JetPack 7.2 AX210/AX200 driver modules

The folder contains:

iwlwifi.ko
iwlmvm.ko

Copy both files to the Jetson, for example under ~/Downloads/, then replace the current kernel modules:

KVER=$(uname -r)
MODULE_DIR=/lib/modules/${KVER}/kernel/drivers/net

# Back up the original modules
sudo cp ${MODULE_DIR}/iwlwifi.ko ${MODULE_DIR}/iwlwifi.ko.bak
sudo cp ${MODULE_DIR}/iwlmvm.ko ${MODULE_DIR}/iwlmvm.ko.bak

# Install the JetPack 7.2 compatible modules
sudo cp ~/Downloads/iwlwifi.ko ${MODULE_DIR}/
sudo cp ~/Downloads/iwlmvm.ko ${MODULE_DIR}/

sudo depmod -a

Install zstd if needed:

sudo apt update
sudo apt install -y zstd

For AX210, decompress the ty-a0-gf-a0 firmware and PNVM files:

cd /lib/firmware
sudo unzstd -f -k iwlwifi-ty-a0-gf-a0-86.ucode.zst
sudo unzstd -f -k iwlwifi-ty-a0-gf-a0.pnvm.zst

For AX200, decompress the cc-a0 firmware files:

cd /lib/firmware
sudo unzstd -f -k iwlwifi-cc-a0-*.ucode.zst

Enable automatic loading at boot:

printf "iwlwifi\ncfg80211\nmac80211\n" | sudo tee /etc/modules-load.d/iwlwifi.conf
sudo depmod -a
sudo modprobe iwlwifi

Realtek RTL8852BE / 8852BE

Download the JetPack 7.2 Realtek 8852BE driver package from the OneDrive folder below:

JetPack 7.2 Realtek 8852BE driver modules

The verified folder path is 8852be/jp7.2/8852be-6.8.12-1021-tegra/, and it contains:

rtw89_core.ko
rtw89_pci.ko
rtw89_8852b.ko
rtw89_8852be.ko
SHA256SUMS
modinfo.txt

Copy the folder to the Jetson, for example under ~/Downloads/8852be-6.8.12-1021-tegra/, then install the modules:

KVER=$(uname -r)
RTW89_DIR=/lib/modules/${KVER}/kernel/drivers/net/wireless/realtek/rtw89
DRIVER_DIR=~/Downloads/8852be-6.8.12-1021-tegra

sudo mkdir -p ${RTW89_DIR}
sudo cp ${DRIVER_DIR}/rtw89_core.ko ${RTW89_DIR}/
sudo cp ${DRIVER_DIR}/rtw89_pci.ko ${RTW89_DIR}/
sudo cp ${DRIVER_DIR}/rtw89_8852b.ko ${RTW89_DIR}/
sudo cp ${DRIVER_DIR}/rtw89_8852be.ko ${RTW89_DIR}/

Install zstd if needed, then decompress the Realtek firmware files:

sudo apt update
sudo apt install -y zstd

cd /lib/firmware/rtw89
sudo unzstd -f -k rtw885*.zst

Update module dependencies and load the driver:

printf "rtw89_8852be\n" | sudo tee /etc/modules-load.d/rtw89_8852be.conf
sudo depmod -a
sudo modprobe rtw89_8852be

note

The module name is rtw89_8852be. Running sudo modprobe 8852be will fail because 8852be is not the kernel module name.

Reboot the Jetson if the wireless interface does not appear immediately:

sudo reboot

Verify Wi-Fi

After rebooting, use the following commands:

# Check PCI device detection
lspci -nnk | grep -A3 -i network

# Check Intel or Realtek Wi-Fi logs
sudo dmesg | grep -Ei 'iwl|rtw89'

# Check wireless interface
ip link show

# Check loaded modules
lsmod | grep -E 'iwl|rtw89'

A successful setup should show the Wi-Fi device, the expected kernel modules, and a wireless interface such as wlan0.

The following AX210 result shows the final Wi-Fi enabled state after repair:

Troubleshooting

Symptom	Check
`lspci` cannot detect the Wi-Fi module	Check M.2 Key E installation and confirm the PCIe lane is enabled by the carrier board device tree.
Intel `dmesg` reports firmware loading failures	Confirm the matching `.ucode` and, for AX210, `.pnvm` files were decompressed under `/lib/firmware/`.
Realtek `dmesg` reports firmware loading failures	Confirm `rtw885*.zst` files were decompressed under `/lib/firmware/rtw89/`, especially the `rtw8852b` firmware files.
`modprobe iwlwifi` reports `Invalid argument`	Check whether `rfkill.ko` exists with `find /lib/modules/$(uname -r) -name "rfkill.ko"`. If it is missing, use the correct BSP image or rebuild the kernel modules.
`modprobe rtw89_8852be` reports module not found	Confirm the four `rtw89*.ko` files were copied to `/lib/modules/$(uname -r)/kernel/drivers/net/wireless/realtek/rtw89/`, then run `sudo depmod -a`.
`modprobe 8852be` fails	Use `sudo modprobe rtw89_8852be`; `8852be` is not the module name.
Wi-Fi disappears after reboot	Confirm `/etc/modules-load.d/iwlwifi.conf` or `/etc/modules-load.d/rtw89_8852be.conf` exists and run `sudo depmod -a` again.
AX210 loads but cannot scan 6 GHz networks	Confirm `iwlwifi-ty-a0-gf-a0.pnvm` exists and check whether the configured regulatory domain supports 6 GHz with `iw reg get`.

Notes

AX210 and AX200 firmware files are not interchangeable. AX210 uses ty-a0-gf-a0; AX200 uses cc-a0.
Realtek RTL8852BE uses the rtw89 driver stack and firmware under /lib/firmware/rtw89/.
These repair packages are built for JetPack 7.2 kernel 6.8.12-1021-tegra.
Avoid using apt upgrade as a workaround on custom Jetson carrier boards. Use a validated BSP image or driver package for the target kernel instead.
