Unable to Connect to Home WiFi with ShawLED Controller

Unable to Connect to Home WiFi with ShawLED Controller

If your ShawLED controller cannot connect to your WiFi network, follow these steps to troubleshoot the issue. This guide also addresses common issues like not being able to discover your lights in the WLED app.

Step 1: Verify Power to the Controller

Check the LEDs on the ESP32 controller board (Usually the biggest, metallic-looking chip on the controller board).

  • Look for a small orange or blue LED on the board. If this LED is illuminated, it indicates the controller is receiving power.
  • If no LED is visible, ensure your power supply is plugged in and functional.

Step 2: Ensure Proper WiFi Connection

Reboot your controller
  1. Unplug the power, wait a few seconds, and plug it back in.
  2. Wait up to 10 minutes, then try discovering lights in the WLED app.

Same WiFI Network
  1. Ensure your phone is connected to the same WiFi network as the ShawLED controller.

Check App Permissions
  • Ensure the WLED app has permission to access devices on your network.
  • On most phones, this setting appears during app installation or in the phone’s privacy/network settings.
  • Without this permission, the app cannot communicate with the controller even if they are on the same network.

Step 3: Check for the WLED-AP WiFi Access Point

While near the controller box, check your phone’s available WiFi networks for WLED-AP:
  • If WLED-AP is visible:
    The controller is in setup mode and not connected to your WiFi network.
    Proceed with reconfiguring your WiFi settings:

    • Connect to WLED-AP

    • Navigate to 4.3.2.1 inside a browser

    • Go to Wifi Settings

    • Input your WiFI SSID and password

  • If WLED-AP is not visible:
    The controller is likely connected to your WiFi network. Troubleshooting steps for this scenario are covered later.


Step 4: Verify Router and WiFi Settings

You may need to log into your router to adjust settings. Use your router's app or type its IP address into a web browser. If you're unsure how to log in, search for instructions specific to your router's make and model.

  1. SSID and Password

    • Double-check the network SSID and password entered during setup.
    • Avoid spaces or special characters in the SSID, as these can cause issues.
    • Some phones add a space after the SSID or password, so make sure yours didn't.
  2. 2.4 GHz Network

    • Confirm your router has a 2.4 GHz band enabled.
    • If your router combines 2.4 GHz and 5 GHz bands under one SSID, separate them in your router settings.
  3. Guest Networks

    • Do not use a guest network, as they block communication between devices.
  4. WiFi/AP Isolation

    • Disable AP Isolation in your router settings, if enabled, to allow device communication.
  5. Router Settings for Stability

    • Set the WiFi channel to 11 and the bandwidth to 20 MHz for better performance on busy networks.

Step 5: Manually Access the Controller

  • Log into your router and find the IP address assigned to the ShawLED controller.
  • Enter the IP address directly into the WLED app or your browser’s URL bar to access the controller.
  • If the WLED app crashes during light discovery, this method often works.

  • Step 6: Advanced Solutions

    If none of the above solutions work:

    1. Reboot both your WiFi router and the ShawLED controller.
    2. Consider using a dedicated WiFi access point for your controller.
      • Recommended Device: The NETGEAR WAC104 Access Point, which works seamlessly with ShawLED.
      • Connect it to your router via Ethernet, set it up as a separate SSID, and make the SSID invisible to keep your main network unaffected.
