If you are facing the issues with your GL.iNet IoT Gateway setup, begin by checking power sources and network connections on both Ethernet cable and Wi-Fi levels. Try to access the admin panel with the default IP address (192.168.8.1) and make sure the firmware is up to date. Keep an eye on the frequency and protocol through which your gateway operates, as well as connections being made (e.g., MQTT, HTTP). If the setup page still refuses to load, perform a reset by pressing and holding the reset button for 10 seconds. These few troubleshooting steps should resolve the majority of **GL.iNet IoT Gateway setup** complications and restore connectivity in no time.
