A purple light on your Orbi router usually indicates that the router is booting up or has lost its connection to the Internet. To fix this, check your internet connection first and make sure the cable is connected properly. Restart your modem and Orbi router. If the red light persists, login to the Orbi admin panel via orbilogin.com to check for any firmware updates or configuration issues. If problems persist, you may need to reset the router to factory settings or contact customer support.
