Follow these steps to check and refine the Wi-Fi connection: 1)Ensure that the Wi-Fi account and password are entered correctly. 2)Remove any special characters, spaces, or symbols (e.g. #, $, %, &, *) from the Wi-Fi name or password. 3)Note that the device does not support 5G Wi-Fi. If you are using a 5G network, switch to a 2.4G Wi-Fi network. 4)If the previous attempts fail, you can try resetting the device.[Turn the dimmer button 3-5 times, LED flashes to indicate a successful reset]. After resetting, reconnect the device to your Wi-Fi.
