WiFi connection drops frequently or app loses control of the grill during cooks.

Safety first: Network troubleshooting does not require opening the grill; unplug before removing the controller.

• Improve signal: Move the router closer, use a WiFi extender, or reposition the grill to reduce obstructions.
• Use 2.4 GHz network: Ensure the grill is connected to a 2.4 GHz SSID, which has better range than 5 GHz.
• Disable router power-saving: Turn off aggressive power-saving or band-steering features that may drop IoT devices.
• Firmware update: Update the GMG app and controller firmware to the latest versions.
• Replace controller if needed: If WiFi remains unstable and other devices work fine on the same network, the controller's WiFi module may be failing and require replacement.
