Joy-Con 2 Repeatedly Connects/Disconnects From the Console
Before you start
You will need:
Your Nintendo Switch 2 console
Your Joy-Con 2 controllers
Remove your console from the dock while troubleshooting.
What to do
Attach the Joy-Con 2 controllers to the console.
If a Joy-Con 2 controller does not register while attached, see Joy-Con 2 Not Recognised or Not Registering While Attached to the Console.
Check that your console has the latest system update. If so, restart it.
Check whether the Joy-Con 2 controllers have the most recent firmware update.
Detach the Joy-Con 2 controllers, then start a game or navigate through the menus to see if the controller or controllers stay connected. If they still disconnect, continue with the next steps.
Press the SYNC Button on each affected Joy-Con 2 controller once to reset it, then press any button, such as the A Button, to pair it again.
Test the Joy-Con 2 while the console is in flight mode.
Activate flight mode from the System Settings menu.
With flight mode enabled, enable Bluetooth as well.
Press a button on each Joy-Con 2 controller to reconnect them.
After the Joy-Con 2 controllers are connected to the console wirelessly, disable flight mode and continue to use the console as normal.
Check for wireless interference. Make sure the console is not placed behind a TV, under a metal object or within four feet of other wireless devices (wireless speakers, cordless phones, etc.).
Test the console with another Joy-Con 2 controller (either left or right) if possible.
Situation not resolved
If the issue persists with only one Joy-Con 2, the Joy-Con 2 will need to be inspected. Please contact us for further assistance.
If the issue persists with multiple Joy-Con 2 controllers, the controllers and console will need to be sent in for inspection. Please contact us for further assistance.
