Lightning device has detected that your current network connection speed is not fast enough to satisfy the playback bandwidth of current music file.
The 'bandwidth' could be your Internet connection speed, if you are playing a TIDAL or Qobuz streaming content or just your home network's speed. The problem usually occurs when your Lightning device is connected to your home network by WiFi but the connection is not stable.

- Consider to purchase a recommended WiFi router by AURALiC or switch to wired (Ethernet) connection.
- Move current WiFi router to a place closer to your Lightning device and music storage device (if connected through WiFi).
- Check out your Internet service provider to see if your Internet connection is fast enough to play online streaming content.
