Wi-Fi Access Point Mode (AM62)

Hello.

I followed the instructions in “How to Setup Wi-Fi Access Point Mode (Linux)” using the AM62, but I can’t see the AP I created from my PC.

I’d like to check if the PACKAGECONFIG:append = “networkd iptc” modification is working. What should I do?

Also, I’ve made changes directly to meta-toradex-demos. Is this appropriate?

Hi, I’m the Toradex AI Assistant.

I might make mistakes or occasionally get you wrong. Our support team will step in if needed.

I can help you troubleshoot your Wi-Fi Access Point setup. However, to provide the most accurate guidance, could you please run the tdx-info command and share which specific version of the OS you’re running? You can find more information about this command at this link.

Checking PACKAGECONFIG Modification

To verify if your PACKAGECONFIG:append = " networkd iptc" modification is working (1), you can check the systemd configuration after building and deploying your image:

  1. Check if systemd-networkd is enabled:

    # systemctl status systemd-networkd

  2. Verify iptables support is compiled into systemd:

    # systemctl --version

  3. Check if the required kernel configs are enabled (1):

    # zcat /proc/config.gz | grep CONFIG_IP_NF_IPTABLES
# zcat /proc/config.gz | grep CONFIG_NF_CONNTRACK
# zcat /proc/config.gz | grep CONFIG_IP_NF_NAT

Troubleshooting Access Point Visibility

Here are some steps to diagnose why your AP isn’t visible:

  1. Check if the uap0 interface exists (1):

    # iw dev

  2. Verify hostapd service status (1):

    # systemctl status hostapd

  3. Check if the interface is properly configured (1):

    # ip a s dev uap0

Regarding meta-toradex-demos Modifications

Modifying meta-toradex-demos directly is generally not the recommended approach. Instead, you should create your own custom layer or modify the systemd recipe in your own layer to avoid conflicts during updates. The proper approach is to create a systemd_%.bbappend file in your custom layer (1).

Once you provide the OS version information, I can give you more specific guidance for your platform.
