Jetson Orin Nano Dev Kit WPA3 Connectivity Issue

Issue Overview

Users of the Nvidia Jetson Orin Nano Dev Kit are experiencing connectivity issues when attempting to connect to Wi-Fi networks secured with WPA3. The primary symptom reported is that the device can only establish a connection to hotspots configured with WPA2 security settings. This issue arises during the setup phase when users are trying to connect their devices to modern Wi-Fi networks that utilize WPA3 for enhanced security.

The specific hardware in question is the AW-CB375NF Wi-Fi module, which is integrated into the Jetson Orin Nano Dev Kit. Users have noted that despite their network supporting WPA3, the device fails to connect unless the network is reverted to WPA2. This limitation has been consistently reported, indicating a potential compatibility issue with the hardware or firmware.

The impact of this problem significantly affects user experience, as many modern routers default to WPA3, and users may find it challenging to connect their devices without adjusting their network settings. The inability to utilize the latest security protocols may also raise concerns about network security for those relying on the Jetson Orin Nano for development projects.

Possible Causes

• Hardware Limitations: The AW-CB375NF module used in the Jetson Orin Nano Dev Kit may not support WPA3, which would prevent users from connecting to WPA3-secured networks.

• Software Bugs: There could be bugs in the device’s firmware or drivers that hinder compatibility with WPA3, leading to connection failures.

• Configuration Errors: Incorrect network configurations or settings on either the Jetson device or the router could result in connectivity issues.

• Driver Issues: Outdated or incompatible drivers for the Wi-Fi module might not support newer security protocols like WPA3.

• Environmental Factors: Issues such as interference or weak signal strength could exacerbate connection problems, although this is less likely given the specific nature of the WPA3 issue.

• User Errors: Misconfigurations by users when setting up their network security settings could also contribute to connectivity challenges.

Troubleshooting Steps, Solutions & Fixes

1. Verify Hardware Specifications:

   • Confirm that your Jetson Orin Nano Dev Kit uses the AW-CB375NF Wi-Fi module. This module is known to support only up to WPA2.

2. Check Firmware and Driver Versions:

   • Ensure that your device’s firmware and drivers are up-to-date. Use the following command in the terminal:

     sudo apt update && sudo apt upgrade
     

3. Network Configuration Review:

   • Review your router’s configuration settings. If possible, temporarily change your router’s security settings from WPA3 to WPA2 and test connectivity.
   • If you need to keep WPA3 enabled, consider configuring a separate SSID for WPA2 connections specifically for use with the Jetson device.

4. Testing Different Configurations:

   • If you have access to another Wi-Fi module or device that supports WPA3, test connectivity with it to confirm whether the issue lies with the Jetson Orin Nano or your network setup.

5. Driver Reinstallation:

   • If you suspect driver issues, consider reinstalling Wi-Fi drivers specific to your module. You can find relevant drivers on Nvidia’s official website or through community forums.

6. Consult Documentation:

   • Refer to Nvidia’s official documentation regarding supported features of the Jetson Orin Nano Dev Kit and any updates related to Wi-Fi connectivity.

7. Community Support:

   • Engage with community forums for additional insights or solutions from other users who may have faced similar issues.

8. Future Prevention:

   • Regularly check for updates from Nvidia regarding hardware capabilities and driver updates that may enhance compatibility with newer security protocols like WPA3.

No definitive solution has been established for enabling WPA3 connectivity on this device as of now, indicating a potential area for further investigation by Nvidia or community developers.
