Nintendo Switch Error Code 2110-2003: How to Get Back on Wi-Fi

What’s Going On

Error 2110-2003 shows up when your Switch can’t connect to your wireless network. According to Nintendo, it usually happens at the very first step, when the console tries to reach the router and before it has been given an IP address. The two causes Nintendo names are incorrect internet settings on the console and the console not being able to find the router.

That makes this a local Wi-Fi problem. It has nothing to do with your Nintendo Account, Nintendo Switch Online, or the game you were trying to play.

Try this first: restart the console, stand within about 10 feet of the router, and set up the connection again from scratch. Those are the first two steps in Nintendo’s own guide.

The steps below apply to Nintendo Switch 2, Nintendo Switch, Switch Lite, and the Switch OLED Model. Test the connection after each one so you know which change fixed it.

The Usual Causes

• A mistyped Wi-Fi password. Passwords are case-sensitive, and symbols are easy to get wrong on the on-screen keyboard.
• The wrong security type saved on the console. If the saved setting doesn’t match the router, the connection fails before it starts.
• A weak signal or interference. Distance, walls, metal furniture, and other electronics all cut into the signal.
• A router or modem that needs a restart.
• A Bluetooth audio device competing with Wi-Fi. Nintendo specifically calls this out for routers that broadcast both 2.4 GHz and 5 GHz.

Troubleshooting, Easiest to Hardest

1. Restart the console

Hold the POWER button for at least three seconds, choose Power Options, then Restart. Putting the console to sleep is not the same thing.

2. Create a new internet connection

Move the console to within 10 feet of the router, then:

• Switch 2: HOME Menu > System Settings > Internet > Internet Settings
• Switch, Switch Lite, OLED: HOME Menu > Settings > Internet > Internet Settings

Pick your network name, enter the password if asked, and wait for the connection test to finish.

3. Power-cycle your modem and router

1. Unplug the power cables from the modem and the router.
2. If the modem’s lights stay on, it has a backup battery. Take it out.
3. Wait 30 seconds.
4. Plug in the modem and wait until its lights are steady.
5. Plug in the router and wait until its lights are steady.

4. Re-enter the password and check the security type

Go to Internet Settings, select your connection under Registered Networks, and choose Change Settings > Security. Pick the type that matches your router. Nintendo lists WEP (Open), WEP (Shared), WPA-PSK (AES), and WPA2-PSK (AES).

Type the password exactly, and tap Show at the top of the keyboard so you can see what you’re entering. Select OK to save.

5. Cut interference and boost the signal

• Put the router somewhere central and as close to the console as you can. If it’s on the floor, raise it.
• Keep the console and router away from metal objects and other electronics. Nintendo’s list includes filing cabinets, speakers, power strips, glass, and cordless phones.
• If you use Bluetooth headphones with the console and your router has both 2.4 GHz and 5 GHz networks, connect the console to the other band.
• Still stuck? Disconnect the Bluetooth audio device and try wired headphones instead.

6. Look at the router itself

If none of that works, Nintendo says the problem is likely the network environment or the router, and points you to the router’s manufacturer for help with two things: updating the router’s firmware, and resetting the router to factory defaults. A router reset wipes your Wi-Fi name, password, and any custom settings, so save it for last.

Pro Tips & FAQs

Tip: Test with a phone hotspot. This isn’t in Nintendo’s guide, but it’s a quick way to split the problem in two. If the Switch connects to your phone’s hotspot, the console is fine and the router is where to look.

Tip: If your router is set to a newer WPA3-only mode, try its mixed WPA2/WPA3 setting. This is also not from Nintendo’s guide, but the security types Nintendo lists for this fix stop at WPA2.

What does Switch error 2110-2003 mean?

The console couldn’t connect to your wireless router. It usually fails before the router assigns the console an IP address.

Is Nintendo’s network down?

That’s not what this code points to. 2110-2003 is about the link between your console and your own router, so start with your home network.

Does this work for the Switch 2?

Yes. Nintendo’s support article covers Switch 2 along with the original Switch, Switch Lite, and OLED Model. The only difference is that the settings menu is called System Settings on Switch 2.

Do I need to send my Switch in for repair?

Probably not. Work through the steps first and try a second network such as a phone hotspot. If the console can’t join any network at all, that’s the point to contact Nintendo support.
