The following article troubleshoots in the event that an iPad is losing connection or won't connect with an M-480.

• Be sure that the correct setup procedure is being followed for wireless setup in the New Features 1.6 Addendum: https://proav.roland.com/global/products/m-480/support/
• Be sure that the M-480 is running at it's latest version:

• Be sure that the iPad version being used is compatible:

• Try deleting the M-480 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-300 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-480 Remote app to delete it. After deleting, reinstall the app from the App Store.

  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.
  Note: The document above is “best practice” and will help ensure a reliable V-Mixer remote app connection and smooth operation for events.
• Note that communication between an iPad and the wireless dongle may take a few moments. In the iPad M-480 Remote App, it may take multiple "Online" attempts for the iPad to communicate.
• If using a wireless USB adapter, be sure that the wireless USB adapter is compatible. The M-480 is compatible with a WNA-1100, WNA-150 or WNA-1 Wireless USB Adapter. While other wireless USB adapters may work, we have not tested others and cannot guarantee compatibility.
  Note: Wireless USB adapters operate at 2.4gHz. Cell phones communicate at 2.4gHz and dropouts can occur if there are a large amount of cell 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.If using a LAN connection with a router, the following article troubleshoots this: M-480: SYMPTOM: Troubleshooting LAN Connection Issues with a Router
• Test with a different iPad (if available) to rule out an issue with the iPad.
• Try initializing the M-480 and test with the console initialized. Be sure to backup settings prior to initializing the console.
