The Linksys Velop red light indicates a connectivity or node failure. If the red light shows, verify your internet connection to ensure that the primary node is correctly linked to the modem. To address temporary difficulties, restart the modem and Velop system. If the red light remains, consider relocating the nodes to improve signal strength or restoring the node to factory settings. Make sure the firmware is up to current by using the Linksys app. A flickering red light may indicate a weak connection, necessitating closer positioning of nodes. If the problem persists, reconfigure the Velop system using the app or online interface. If troubleshooting fails, Linksys help may be required to address underlying connectivity issues and restore network functionality.
