Hi! I see you’re having trouble connecting your Flame Boss FB400 to your WiFi. I’d love to help you get it up and running. To start, could you tell me a bit about what’s happening when you try to connect? For example, do you get any specific error messages, or does the controller’s LED blink in a certain pattern? Also, what type of WiFi network are you trying to connect to—2.4 GHz or 5 GHz?

Meanwhile, here are some initial steps that often help with FB400 WiFi connection issues:

1. Check the Controller's WiFi Mode:
The FB400 has two modes—Access Point (AP) mode and Station mode. The LED blinking pattern can tell us which one it’s in:
- Slow blinking LED means it’s in AP mode (it creates its own WiFi network for your phone to connect temporarily to configure).
- Fast blinking LED means it’s in Station mode (it’s trying to connect to your router's WiFi).
Make sure it’s in the proper mode depending on the step you’re at.

2. Reboot Your WiFi Router:
Sometimes simply restarting your home WiFi router can clear connection issues.

3. Confirm Frequency Band:
The FB400 only works on 2.4 GHz networks, not 5 GHz. If your router runs dual bands (2.4 and 5 GHz), ensure your device is connecting to the 2.4 GHz band. You might want to temporarily disable the 5 GHz band on your router to test this.

4. Distance and Interference:
Ensure the FB400 is within a good range of your router and there aren’t too many obstacles or interference sources.

Could you please check the LED pattern on your FB400 and confirm the WiFi network type you’re trying to connect to? That will help me guide you through the next steps precisely.

If you'd like, I can also guide you through reconnecting your device using the Flame Boss app. Let me know!
