A Linksys Velop node blinking red is indicating a connectivity issue, which is frequently brought on by the node losing communication with the internet or the parent node. Verify your internet connection and make sure the node is within range of the main node. Use the Linksys app to reconnect or check settings after restarting the node. Reset the node to factory settings and reconfigure it if the problem continues. For more help, get in touch with Linksys WiFi Customer Service for knowledgeable guidance.
