To connect Alexa to WiFi for optimal performance, ensure your router is configured to prioritize QoS (Quality of Service) settings. This will allocate a dedicated band with sufficient bandwidth to handle voice commands and data streaming. Enable QoS by logging in to your router's web interface, selecting the 'Advanced Settings' or 'QoS Settings,' and configuring the following: Set up separate Quality of Service policies for Alexa's device (typically 192.168.0.1 or 10.0.0.1) and other high-priority devices like smart TVs. Allocate a minimum of 128 Mbps to ensure smooth voice commands, video streaming, and music playback. You can also consider setting up a custom QoS rule for Alexa's device using the 'Device Priorities' feature in some routers. This will give priority traffic to your Echo device during peak usage hours (e.g., 7-10 am and 4-7 pm) or at any time you prefer. Once set up, your router should now be able to provide a stable and fast connection for Alexa, ensuring seamless voice commands and quick responses.
