But life is not perfect. I see many people complaining about "Alexa" disconnecting constantly. This was true even in my house WiFi configuration. Every day after work I was having to re-connect the gadget to the network which was annoying
You will know this is your problem if you have an Orange ring:

Just assign a Static IP to Alexa - Amazon Echo in my router. The steps will vary based on your router but the idea is the same. Find Alexa network MAC address and give it a permanent / static IP address in your router and don't use DHCP for giving it an automatic IP.
