The following article troubleshoots in the event that an iPad is losing connection or won't connect with an M-200i.

• Be sure that the M-200i is running at it's latest version:
  M-200i System Program
• Be sure that the latest version of M-200i Remote App is being used:

• 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.
  
  
• If connecting wirelessly, communication between an iPad and the wireless dongle or router may take a few moments. In the iPad M-200i Remote App, it may take multiple "Online" attempts for the iPad to communicate.
  
  
• If using a wireless USB adapter:
• Be sure that only a Roland WNA-1100RL or a Roland WNA-1 (also called an Onkyo UWF-1) adapter is compatible.
• Be sure to turn on Ad Hoc mode using the instructions found on page 104 of the manual:
  Roland Pro A/V - M-200i | 32-Channel Live Digital Mixing Console
  
  
  Note: Wireless USB adapters operate at 2.4gHz. Cel phones communicate at 2.4gHz and dropouts can occur if there are a large amount of cel phones in the area. Using a router set to 5gHz that's connected to the M-200i's LAN port, instead of a wireless USB adapter, can often resolve dropouts that are occurring because of the 2.4gHz interference. Setup instructions can be found on page 2 of the M-200i Remote Setup Guide:
