Nintendo Switch Error Code 2110-4500 — What It Means & How to Fix It

What Does This Error Mean?

2110-4500 means your Nintendo Switch could not connect to your Wi-Fi network. The Switch detected the network but was unable to complete the connection. This is usually a password issue, router setting, or signal problem.

Affected Models

Nintendo Switch
Nintendo Switch Lite
Nintendo Switch OLED

Common Causes

You entered the wrong Wi-Fi password when setting up the connection on the Switch
The Wi-Fi signal is too weak where you are using the Switch
Your router uses a security type or frequency band that the Switch cannot handle
Your router is assigning too many IP addresses and your Switch cannot get one
The router's MAC address filtering is blocking the Switch from connecting

How to Fix It

Delete and re-enter your Wi-Fi connection. On the Switch, go to System Settings > Internet > Internet Settings. Find your network, select it, and choose Delete Settings. Then reconnect by selecting the network and re-entering the password carefully.

Re-entering the password from scratch is the most effective way to rule out a typo or mistyped password as the cause.
Move closer to your router. Bring the Switch within a few meters of the router and retry the connection. If it connects when close, the signal is too weak in your usual location.

The Nintendo Switch Lite has a smaller antenna than the standard Switch. It is more sensitive to distance and wall obstructions.
Restart your router. Unplug it from power for 30 seconds and plug it back in. Once it fully reconnects, try connecting the Switch to Wi-Fi again.

Router restarts clear cached device information and refresh IP address assignments, resolving many connection refusals.
Switch to the 2.4 GHz band. When connecting to Wi-Fi on the Switch, choose the 2.4 GHz version of your network if your router broadcasts both 2.4 GHz and 5 GHz separately.

The Nintendo Switch supports both 2.4 GHz and 5 GHz, but 2.4 GHz travels further through walls and is more reliable in many home setups.
Disable MAC address filtering on your router. Log in to your router's admin page (typically at 192.168.1.1). Find MAC Filtering or Access Control and disable it. Then retry the Switch connection.

Your Switch's MAC address can be found at System Settings > Internet. Add it to the allowed list if you prefer to keep MAC filtering enabled.

When to Call a Professional

If your Switch cannot connect to any Wi-Fi network at all — even when standing next to the router — the internal Wi-Fi chip may be failing. Contact Nintendo Support at support.nintendo.com for a hardware assessment. The Switch Lite in particular has a non-removable Wi-Fi module that requires professional service.

Frequently Asked Questions

Why does my Switch get 2110-4500 but my phone connects fine?

Phones and game consoles use different Wi-Fi chips and connect in slightly different ways. Your router may block the Switch's connection attempt while allowing phones through. Common culprits are MAC filtering, a full DHCP address pool, or a 5 GHz-only network that the Switch is struggling to maintain.

Does the Nintendo Switch Lite have worse Wi-Fi than the regular Switch?

The Switch Lite has a smaller form factor with a more compact antenna. In practice, it can have slightly weaker Wi-Fi reception than the standard Switch, especially in rooms far from the router. Using the Switch Lite closer to the router or using a Wi-Fi extender helps compensate.

Can I connect the Nintendo Switch with an ethernet cable instead of Wi-Fi?

Yes, but you need a USB ethernet adapter. Nintendo sells an official LAN adapter for the Switch dock. With the Switch docked and the LAN adapter plugged in, go to System Settings > Internet > Internet Settings and select the wired connection. A wired connection is significantly more reliable than Wi-Fi for online gaming.
