LM816 USB WIFI not working

Technical Support

Hello,
We used to use the LM816 USB WIFI wireless dongle with your Colibri T20 product. Now we will use it with the Colibri IMX6 product. However, I cannot run the dongle on the T20 at the moment.

Let me try to briefly explain what I did. I installed the driver from the https://developer.toradex.com/hardware/accessories/wireless/lm816-usb-wifi/ website on the CE6 loaded T20 module and plugged the dongle. The WIFI icon appears at the bottom right, when we double click on the icon, it does not list the surrounding WIFIs in the window that opens. In this case, I think the dongle is not working properly. Is there anything else I need to do other than installing the driver? I would be very happy if you could inform me.

Best regards,

Mehmet Karabudak

Hello!

The LM816 USB WiFi adapter is specifically designed for use with Windows CE and is not recommended for Embedded Linux. If you are using Windows CE6 or CE7, you can install the necessary driver by downloading the CAB file from the Toradex website. Detailed installation instructions are also available there.

For Windows CE, the LM816 USB WiFi is compatible with both the Colibri T20 and Colibri iMX6 modules.

If you are working with Embedded Linux and experiencing WiFi connectivity issues, consider the following general troubleshooting steps:

  1. Check Compatibility: Ensure that your WiFi adapter is supported by the Linux kernel version you are using.
  2. Driver Installation: Verify that the correct drivers are installed and loaded. You can check this using commands like lsmod to list loaded modules.
  3. Network Configuration: Confirm that your network settings are correctly configured, including SSID and security settings.
  4. Logs and Diagnostics: Review system logs using dmesg or journalctl for any error messages related to WiFi.
  5. Signal Strength: Ensure that the WiFi signal is strong enough for a stable connection.

I hope this helps! If you have any more questions about using Toradex hardware with Embedded Linux, feel free to ask.

Best regards,
Toradex AI Assistant.

Hi @mehmetkarabudak78 ,

Sorry, but write that you used LM816 succesfully on T20 in the past, and now you want to use it on iMX6… So is it not working on T20 or iMX6 on your current tests?

What version of the OS Image are you using on your tests? (which version were you using in the past, when it still worked?)

If the WiFi icon appears, it means that the driver is loaded and it should work… strange that you see no networks. Maybe some conflicting registry settings in your system? Did you try to clear the registry and boot with clean registry?
Are you using our standard image or build y custom one?

Did you try to check if there is some error message on the debug serial port when pluggin in the LM816?
