Nintendo Switch Error Code 2107-0445 — What It Means & How to Fix It

What Does This Error Mean?

Error 2107-0445 means the Nintendo Switch is having trouble connecting to a Joy-Con controller. The Joy-Con is either not paired, has lost its pairing, or there is wireless interference preventing the connection. This affects gameplay directly since the Joy-Con will not respond to inputs.

Affected Models

Nintendo Switch
Nintendo Switch OLED

Common Causes

The Joy-Con has lost its wireless pairing with the Switch
The Joy-Con battery is very low and cannot maintain a stable connection
Wireless interference from other devices (routers, microwaves, baby monitors) is disrupting the signal
The Joy-Con's internal Bluetooth antenna is damaged — more common after drops
The Joy-Con rail (the sliding track) has damage preventing a solid physical connection when attached

How to Fix It

Re-pair the Joy-Con. Detach the Joy-Con from the Switch, then reattach it by sliding it back onto the rail. The Switch should detect it immediately when attached.

When attached to the rail, Joy-Cons do not need Bluetooth — they connect via the physical rail connector.
Charge the Joy-Con fully. Attach it to the Switch for at least 30 minutes. A Joy-Con with a dying battery will disconnect frequently.

You can check Joy-Con battery levels by pressing the Home button to see the battery icons on the Home screen.
Re-pair the Joy-Con wirelessly. Go to System Settings > Controllers and Sensors > Change Grip/Order. Hold the small circular pairing button on the Joy-Con until the indicator lights flash.

This forces the Switch to search for and pair with the Joy-Con as if it were new.
Move away from sources of wireless interference. Turn off or move away from Wi-Fi routers, other Bluetooth devices, and microwaves. Try pairing in a different room.

The Joy-Con uses Bluetooth, which operates on 2.4 GHz — the same frequency as many household devices.
Update the Joy-Con firmware. Connect the Joy-Con to the Switch via the rail and go to System Settings > Controllers and Sensors > Update Controllers. Install any available updates.

Firmware updates can fix connectivity bugs and improve Bluetooth stability.

When to Call a Professional

If a Joy-Con consistently fails to connect or disconnects during gameplay, it may have a hardware fault. Nintendo offers free Joy-Con drift and connectivity repairs in many regions — check support.nintendo.com for details. If the Joy-Con is out of warranty, replacement Joy-Cons can be purchased individually.

Frequently Asked Questions

Why does my Joy-Con work when attached but disconnect when wireless?

Joy-Cons have two connection methods: physical (via the rail) and wireless (via Bluetooth). When attached, they use the physical connection, which is always reliable. When detached for wireless use, they rely on Bluetooth, which can be affected by range, battery, and interference. If wireless mode is the problem, try re-pairing and ensuring you are within 5 meters of the Switch.

Does Nintendo repair Joy-Con connection issues for free?

In many countries, Nintendo has offered free repairs for Joy-Con issues including connectivity and the well-known drift problem. Go to support.nintendo.com, navigate to Joy-Con repair, and check if your region is eligible. Repairs through Nintendo typically take 1 to 2 weeks.

Can I use other Bluetooth controllers with the Nintendo Switch instead?

Yes. The Nintendo Switch supports a range of Bluetooth controllers including the Pro Controller, third-party controllers, and even some PlayStation and Xbox controllers with an adapter. Go to System Settings > Controllers and Sensors > Change Grip/Order to pair a new controller.
