Important:
Make sure your PC or mobile device is in the same Wi-Fi network when customizing the Razer Key Light Chroma.
If your router is with Delivery Traffic Indication Message or DTIM, change the default DTIM value which is three to one. This is to ensure timely message delivery to connected devices. Refer to your router’s manual for a guide in changing DTIM values.
