If closing down Apps doesn't stop connection or performance problems between your AirTurn BT-105 and your iPad, you may need to reset the iPad's Network
Settings. This resets WiFi and Bluetooth back to factory default. This process erase WiFi passwords, so write them down before going through this process.
1. Go to your iPad's settings
2. Scroll down the right column and tap the "Reset" button on the bottom
3. On the next screen, tap the "Reset network settings" button
4. The iPad may ask you for your Apple ID and Password. It will reboot, and Network Settings should be cleared.
