RTL8852BE Wireless Module for Jetson
The RTL8852BE is a Wi-Fi 6 (802.11ax) M.2 wireless module based on the Realtek chipset. It integrates a PCIe interface for WLAN and a USB interface for Bluetooth, delivering significantly higher throughput and lower latency compared to previous-generation Wi-Fi 5 modules. It is ideal for embedded devices such as reComputer J4012 that require high-performance wireless connectivity.

Driver Installation
The RTL8852BE module may be detected by the Jetson as a PCIe device but may not have its driver loaded automatically. You will need to install the driver manually depending on your JetPack version.
lspci | grep -i network
JetPack 5.x
For JetPack 5, use the lwfinger/rtw8852be driver:
git clone https://github.com/lwfinger/rtw8852be.git
cd rtw8852be/
sudo apt-get update
sudo apt-get install make gcc linux-headers-$(uname -r) build-essential git
make
sudo make install
sudo modprobe 8852be
JetPack 6.x
For JetPack 6, use the rtw89 driver:
git clone https://github.com/a5a5aa555oo/rtw89
cd rtw89
Edit the Makefile to set the correct kernel headers path:
# JP 6.2
KDIR ?= /usr/src/linux-headers-5.15.148-tegra-ubuntu22.04_aarch64/3rdparty/canonical/linux-jammy/kernel-source/
# JP 6.0
KDIR ?= /usr/src/linux-headers-5.15.136-tegra-ubuntu22.04_aarch64/3rdparty/canonical/linux-jammy/kernel-source
Then build and install:
make
sudo make install
sudo modprobe rtw89_8852be
Verify the Wireless Module
The interface name may vary depending on the JetPack version:
- JetPack 5: typically
wlan0 - JetPack 6: may appear as
wlP1p1s0
Adjust the interface name in the commands below accordingly.Use following command to figure out:
ifconfig
Configure the Wireless Network
Scan for Nearby WiFi Networks
sudo iw dev wlan0 scan | grep -E "SSID|freq"
Replace wlan0 with your actual interface name if different.
Connect to a WiFi Network
sudo nmcli device wifi connect "YOUR_SSID" password "YOUR_PASSWORD" ifname wlan0
Verify WiFi 6 Connection
Check the current link status:
iw dev wlan0 link
The output will show information such as:
- freq: The operating frequency (e.g., 5180 MHz corresponds to 5 GHz band)
- HE-MCS: The Wi-Fi 6 modulation and coding scheme (e.g., MCS 9 represents the highest coding efficiency)
- TX/RX rate: The current transmit and receive speeds
Bluetooth Configuration
The Bluetooth functionality of the RTL8852BE module can be configured using bluetoothctl:
bluetoothctl
