Some phones will give an error message when connecting to "Flair WiFi xxxx" network. It can be something like: "No Internet access" or "No Data" or "Bad WiFi network". The device is warning that there is no internet connection.
This is okay. The Puck's WiFi is a private, local network, and is not connected to the internet. It is only used during WiFi Setup.
Select YES or ACCEPT to allow the connection and then continue with WiFi Setup.
