How do I Connect my Fujitsu AC to WiFi?

Connecting your Fujitsu air conditioner to WiFi allows you to control and monitor your AC unit remotely using a mobile app. To achieve this, you’ll need the FGLair app, a compatible wireless router, and a mobile device running Android 5.0+ or iOS 9.0+. This comprehensive guide will walk you through the step-by-step process of setting up your Fujitsu AC with WiFi connectivity.

Router Compatibility

The first step is to ensure your wireless router is compatible with the Fujitsu air conditioner. The router must support the IEEE802.11b/g/n wireless communication standard and operate on the 2.4 GHz frequency band, using channels 1 to 13. Older routers using the 5 GHz band or incompatible wireless standards may not work.

Mobile Device Compatibility

Next, verify that your smartphone or tablet is running Android 5.0 or later, or iOS 9.0 or later. The FGLair app, which is required for the setup, is compatible with these operating system versions.

Account Registration

Before you can begin the pairing process, you’ll need to create a user account with the FGLair app. This will allow you to manage your Fujitsu AC unit through the mobile app.

  1. Download and install the FGLair app on your Android or iOS device.
  2. Launch the app and select “Create an Account.”
  3. Enter your email address, password, and any other required information.
  4. Review and accept the Terms of Service.

Wireless LAN Connection Setup

Now, it’s time to set up the wireless LAN connection between your Fujitsu AC, router, and mobile app. Follow these steps carefully:

  1. Press the Setup Button on the W-LAN Adapter: Locate the setup button on the W-LAN adapter of your Fujitsu AC unit and press it. Confirm that the indicator lamps turn on, indicating the adapter is in setup mode.

  2. Select the World Region: When launching the FGLair app for the first time, you’ll be prompted to select the world region where your Fujitsu AC is installed.

  3. Enter Account Information: In the app, enter the email address and password you used to create your FGLair account.

  4. Select the W-LAN Adapter SSID: The app will display a list of available W-LAN adapters. Select the SSID (network name) of the adapter you’re connecting to.

  5. Enter the W-LAN Adapter PIN Code: Locate the PIN code printed on the W-LAN adapter and enter it in the app, then tap “Connect.”

  6. Select the WiFi Access Point: The app will now display a list of available WiFi access points (your home router). Select the one you want to connect the Fujitsu AC to.

  7. Enter the WiFi Password: Type in the password for your home WiFi network, then tap “Connect.”

The entire setup process can take up to 15 minutes, depending on your network environment. Be patient and follow the on-screen instructions carefully.


If you encounter any issues during the setup process, here are some troubleshooting tips:

  • Ensure your router and mobile device meet the compatibility requirements.
  • Verify that the W-LAN adapter’s indicator lamps are turned on and blinking, indicating it’s in setup mode.
  • Double-check the PIN code printed on the adapter and ensure you’ve entered it correctly.
  • Make sure you’re selecting the correct WiFi access point and entering the right password.
  • If the connection still fails, try resetting the W-LAN adapter and starting the process again.
