Nintendo Switch Error Code 2110-4106 — What It Means & How to Fix It

What Does This Error Mean?

Error 2110-4106 means your Nintendo Switch cannot establish a Wi-Fi connection. This is a wireless networking error — your Switch is having trouble talking to your router. The fix is usually simple and does not require any technical expertise.

Affected Models

Nintendo Switch
Nintendo Switch Lite
Nintendo Switch OLED

Common Causes

The Wi-Fi password entered on the Switch is incorrect or has changed
Your router is set to a Wi-Fi channel or security mode the Switch does not support
The distance between your Switch and router is too great, causing a weak signal
Your router's MAC address filtering is blocking the Switch from connecting
There is a temporary glitch in your router's DHCP server that is not assigning an IP address

How to Fix It

Delete the Wi-Fi network from your Switch and reconnect from scratch. Go to System Settings > Internet > Internet Settings, select your network, scroll down and select Delete Settings. Then reconnect and re-enter your password.

A wrong password or outdated settings are the most common causes of this error.
Restart your router. Unplug it, wait 60 seconds, and plug it back in. Once all lights are stable, try reconnecting your Switch.

Router restarts clear connection tables and resolve most temporary Wi-Fi issues.
Move your Switch closer to the router. The Nintendo Switch has a moderate Wi-Fi range — walls and distance significantly weaken the signal.

If the Switch connects reliably near the router but not farther away, distance or interference is the issue.
Check your router's security settings. The Nintendo Switch works best with WPA2 security. If your router is set to WPA3-only or a very old WEP setting, try changing it to WPA2 or WPA2/WPA3 mixed mode.

The Switch does not support WPA3-only mode as of early 2026.
Disable MAC address filtering on your router if it is enabled. Log into your router's admin panel (usually at 192.168.1.1) and look for MAC filtering. Either disable it or add your Switch's MAC address to the allowed list.

You can find your Switch's MAC address under System Settings > Internet > Internet Settings > your network > Advanced Settings.

When to Call a Professional

If you cannot connect after all troubleshooting steps, your Switch's Wi-Fi antenna may be damaged. This is a hardware issue that requires service from a Nintendo authorized repair center. Nintendo Switch Lite has a fixed antenna — physical damage to the unit can affect Wi-Fi reception.

Frequently Asked Questions

My other devices connect to Wi-Fi fine. Why won't my Switch?

Different devices have different Wi-Fi chips with different compatibility. The Switch is known to have trouble with certain router security settings like WPA3 and some 5GHz channels. Try connecting your Switch to the 2.4GHz band of your Wi-Fi instead of 5GHz — it has better range and compatibility.

What is a MAC address and how do I find my Switch's MAC address?

A MAC address is a unique identifier for your Switch's Wi-Fi hardware — like a serial number for its network card. Go to System Settings > Internet > Internet Settings, select your connected network, then Advanced Settings to see it. It looks like six pairs of letters and numbers, for example 00:1A:2B:3C:4D:5E.

Will a Wi-Fi extender help if my Switch is far from the router?

Yes — a Wi-Fi extender (or mesh Wi-Fi node) can significantly improve signal strength in rooms far from the router. Place the extender halfway between your router and where you play. Make sure the extender broadcasts the same network name (SSID) for seamless switching.
