Differential
Likely causes of “Nintendo Switch console codes 2110-4011, 2110-4116 and 6 more”, and how to tell them apart
- 1
The console is too far from the router or in the dock
What separates it The code appears when you move around or with the console docked behind a TV
How to confirm Hold the console within 10 to 15 feet of the router and out of the dock, and see whether the connection holds
- 2
The console went to sleep with a low battery
What separates it The code is 2110-4004 or appears after the screen turned off
How to confirm Check the battery level; Nintendo says to connect the AC adapter or dock the console before sleep mode if the charge is nearly gone
- 3
Wireless interference from objects or a Bluetooth audio device
What separates it The code comes and goes, and metal objects, speakers, power strips, glass or cordless phones sit near the console or router
How to confirm Move them away, disconnect any Bluetooth audio device and try the 5 GHz band, since some devices interfere with 2.4 GHz
- 4
The router was powered off, restarting or overloaded
What separates it Other devices on the network also dropped at the same moment
How to confirm Look at the router's lights and power cycle the modem and router; retest once the lights are steady
- 5
A short-term network fault outside your home
What separates it The problem clears on its own and shows up at certain times of day
How to confirm Wait a while and try again later, or use a different network to see whether the fault is local
Before you touch a setting
Record this first — changing settings destroys the evidence
- The exact code and the message, especially any mention of sleep mode or a lost connection
- Where the console was in relation to the router, and whether it was docked
- Whether a Bluetooth audio device was connected when it dropped
- Whether the router restarted or other devices lost their connection at the same time
Try in this order
0 of 8 completedWhat to do first
Reversiblemove the console within 10 to 15 feet of the router, take it out of the dock and keep it awake while you retry.
Correct only the documented fault domain
ReversibleReduce interference (metal objects, speakers, power strips, glass and cordless phones near the console or router), disconnect a Bluetooth audio device, try the 5 GHz band, restart the console and power cycle the network, and use a wired connection if the signal cannot be fixed.
Restart the console and update it
ReversibleCheck for the latest system update; if the console is up to date, hold POWER for three seconds and choose Restart. Nintendo puts this first for 2110-4004.
Bring the console close and out of the dock
ReversibleMove it within 10 to 15 feet of the router. Nintendo also suggests removing the console from the dock during troubleshooting, then returning it once the connection holds.
Reduce interference
ReversibleMove filing cabinets, speakers, power strips, glass and cordless phones away from the console and router. Disconnect any Bluetooth audio device and use wired audio or connect on the 5 GHz band.
Restart the software that was running
ReversibleFor 2164-0056, close the game or app and start it again first, then run the network steps if the code returns.
Try another band, DNS or network
ReversibleConnect on the other band if the router offers one, try an alternate DNS where the article says so, and if the code persists try a different network or access point.
Use a wired connection where you can
ReversibleA cable removes signal strength from the problem. Nintendo also says a USB LAN adapter or a dock with a LAN port is needed, and the console must be docked in TV mode.

What Nintendo's article says about each code
Nintendo publishes a separate article for every code below, and the fix on this page is the fix all of them share. The line beside each code is what that code's own article adds: the message, the situation, or the one step that differs.
- 2110-4011
- The console lost its connection to the wireless router or access point, often because you moved too far away, the signal is weak or the router was powered off.
- 2110-4116
- Disconnected from an online match with "Connection with the network device was lost"; the network dropped or timed out.
- 2123-0209
- The message reads "The connection to the server was lost.
- 2123-0102
- Wait and retry, reduce wireless interference, increase signal strength and try a different network.
- 2123-0301
- Unable to connect to an online service; Nintendo asks for a restart, an alternate DNS and a different wireless band.
- 2124-7403
- May suggest a temporary problem in the network environment; try again later, then another network or access point.
- 2164-0056
- The console tried to connect but the connection was interrupted; Nintendo separates wireless and wired steps and starts with restarting the software.
- 2154-6027
- An online feature failed; Nintendo asks you to check network status and to reduce wireless interference and improve signal strength.
Stop boundary
When this stops being a self-service repair
- !If the console drops on every network you try, contact Nintendo Support with the code
- !Router firmware updates belong to the router's maker, so ask them before updating
- !Keep the AC adapter or dock connected while you test 2110-4004 so the battery is not the variable

Where the manufacturer's article stops. These articles describe a connection that existed and then went away. They do not cover a console that could never connect (2110-1xxx to 2110-3xxx) or a match that failed to start (2318 and 2618 codes).

Common questions
What does 2110-4011, 2110-4116, 2123-0209, 2123-0102, 2123-0301, 2124-7403, 2164-0056, 2154-6027 mean on a Nintendo Switch console?+
an established connection was lost: the console left range of the router, went to sleep, timed out, or the wireless signal was too weak or noisy to hold
Why do I get 2110-4004 after sleep?+
The internet connection was lost because the console entered sleep mode. Nintendo suggests connecting the AC adapter or docking the console before sleep if the battery is low.
Is 2110-4116 my fault or Nintendo's?+
Nintendo describes it as your wireless network or internet connection dropping or timing out, so start with signal and interference, not the console.
Does moving the router help?+
Yes for weak signal: Nintendo suggests a central location as high off the floor as practical, and closer to the console.
Can a Bluetooth headset cause this?+
Nintendo says some Bluetooth audio devices interfere with the 2.4 GHz band, so disconnect one or connect to the 5 GHz band when a code repeats.
What should I do if the code only shows at night?+
Try a different network to see whether it is your provider; Nintendo says a problem with your internet service may resolve later without changes.
