Hello,
Keep in mindYou need an active Wi-Fi connection for Alexa to work. An active Wi-Fi connection means that Alexa can stream music and other media from the Cloud, and answer your questions or process your requests.
Place your Alexa device in an ideal location• Make sure your Alexa device is at least eight inches away from walls or other objects that may cause interference (like microwave ovens or baby monitors).
• If your Alexa device is on the floor, move it to a higher location.
Be clear
• Make sure there is no background noise when you speak to Alexa.
• Speak naturally and clearly to Alexa.
Be specific• Repeat your question or request.
• Rephrase your question or make it less general. For example, there are many cities around the world called "Paris." If you want to know the weather in Paris, France, say, "What's the weather like in Paris, France?"
• Check the Alexa app to see what Alexa heard. On the Home screen, select Learn more at the bottom of the interaction card. You can read what Alexa heard, listen to your request, or provide feedback.
