The following article troubleshoots in the event that an iPad is losing a docked connection but is maintaining a wireless connection with an M-200i.

1. Be sure that the M-200i is running at it's latest version:
   https://proav.roland.com/global/products/m-200i/downloads/
2. Be sure that the latest version of M-200i Remote App is being used:
   https://itunes.apple.com/us/app/m-200i-remote/id588276040?mt=8
   
3. Try deleting the M-200i Remote App from the iPad and then reinstalling from the App Store.
• To delete the app, go to the Home screen on the iPad (press the Home button below the screen). Find the icon for the M-200i Remote app and press and hold it for a few seconds until it wiggles. Then press the (x) badge that pops up in the corner of the M-200i Remote app to delete it. After deleting, reinstall the app from the App Store.
  
4. The following downloadable document shows how to increase V-mixer iPad remote control app connection stability.

   The iPad is designed to work with various applications often running in a multi-task mode. However, the V-mixer remote app requires continuous communication with the V-mixer to maintain the connection. Therefore it is a good idea to “lock” the app to the V-Mixer and maintain a steady connection for the duration of the event.
   
   The document above is “best practice” and will help ensure a reliable V-Mixer remote app connection and smooth operation for events.
   
   
5. Test with a different iPad (if available) to rule out an issue with the iPad.
   
   If the problem continues with a different iPad, the dock cable or the the M-200i itself may be malfunctioning. Unfortunately, without having a second dock cable, we cannot determine if the issue is due to a bad cable or a malfunction on the M-200i itself.
   
   A new dock cable can be purchased through your nearest authorized dealer or through Backstage (Roland Account required).
