Differential
Likely causes of “Nintendo Switch console codes 2110-3129, 2110-3000 through 2110-3999 and 9 more”, and how to tell them apart
- 1
A manual DNS entry that no longer works
What separates it The connection was set up years ago with a manual DNS, or someone typed one while troubleshooting
How to confirm Open the saved connection, look at DNS Settings, and switch it to Automatic; if the code clears, the manual DNS was the fault
- 2
The internet provider's DNS service is failing
What separates it Other devices on the network also load some sites slowly or not at all
How to confirm Enter 8.8.8.8 as the primary and 8.8.4.4 as the secondary DNS on the console; success there proves your provider's DNS was the fault
- 3
A proxy setting that is switched on when no proxy exists
What separates it The connection page shows Proxy Settings on, the code is 2110-3150, 2318-1200 or 2809-1028
How to confirm Set Proxy Settings to Off unless your network requires a proxy, as Nintendo says, and retest
- 4
A network that requires a specific DNS, or blocks the console
What separates it The network is a school, office or shared building that assigns its own DNS or filters
How to confirm Ask the network administrator whether a specific DNS is required; Nintendo says to contact them
- 5
A slow, noisy or weak connection timing out
What separates it The code is 2811-1006 or 2160-8028 and the signal bars are low or downloads crawl
How to confirm Improve signal, try the other band or a wired connection, and run the console's connection test to read the download speed
Before you touch a setting
Record this first — changing settings destroys the evidence
- The exact code and the message shown with it
- The current setting of DNS Settings, Proxy Settings and MTU on the saved connection
- Whether other devices on the network load websites normally
- Whether the code changes after you enter 8.8.8.8 and 8.8.4.4 as the DNS

0 of 8 completedWhat to do first
Reversibleopen the saved connection and make sure DNS Settings and any proxy setting are on Automatic unless your network requires otherwise.
Correct only the documented fault domain
ReversibleRestart the console, set DNS back to Automatic, power cycle the modem and router, then enter 8.8.8.8 as the primary and 8.8.4.4 as the secondary DNS to test whether your current DNS is the fault, and retry later if the internet provider is at fault.
Restart the console and check the DNS setting
ReversibleHold POWER for three seconds and restart, then open the saved connection and check DNS Settings. If it says Manual and your network does not require that, change it to Automatic so the router supplies the DNS.
Power cycle the modem and router
ReversibleUnplug both, wait 30 seconds, plug in the modem and wait for steady lights, then the router; if the modem stays lit when unplugged it has a backup battery to remove. Retest with Test Connection.
Test an alternate DNS
ReversibleIn DNS Settings choose Manual, press B to clear the existing entry, enter 8.8.8.8 as the primary and 8.8.4.4 as the secondary, and save. These are Google's public DNS, which Nintendo suggests as a test; Google's terms apply, and other public DNS work the same way.
Check proxy and MTU
ReversibleSet Proxy Settings to Off unless you connect through a proxy, and keep MTU at the default value of 1400 that Nintendo recommends for most home networks, unless your provider tells you otherwise.
Check the network beyond the console
ReversibleOn another device with a browser, confirm that websites load. If they do not, the network has no internet and the next call is your internet provider or network administrator, not Nintendo.
Improve signal and try again later
ReversibleBring the console within 10 to 15 feet, out of the dock, move interference away and try the other band. Nintendo notes that if the provider is at fault the console may work later without any change.
Every code on this page
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.
- 2110-3129
- A potential issue with the DNS in use, either a wrong DNS typed into the console or a problem with the internet service or DNS service.
- 2110-3000 through 2110-3999
- A general range (2110-3000 to 2110-3999) for connection errors after the console reaches the router; Nintendo asks you to confirm other devices have internet and to check the DNS setting.
- 2110-3127
- Nintendo's steps: check the saved connection's DNS settings, set them to Automatic if a manual DNS is not required, and try an alternate DNS.
- 2110-3150
- Wireless connection failed; Nintendo asks you to check the DNS and Proxy settings and set both to their defaults if they are not required.
- 2122-1006
- Unable to connect to a wired or wireless network; the article gives the same DNS steps as 2110-3129.
- 2318-0203
- The console cannot connect to an online service; Nintendo points at the DNS being used, either typed wrongly or a problem with the provider's DNS.
- 2618-0203
- Same DNS message as 2318-0203, with the same wireless and wired steps.
- 2318-1200
- Nintendo's steps: check the DNS and Proxy settings on the saved connection and set them to Automatic or Off where they are not required.
- 2809-1028
- Check DNS and Proxy settings; the article lists every field on the connection page, including MTU, proxy and hidden network.
- 2811-1006
- Unable to link a Nintendo Account; Nintendo says it is a DNS problem or a timed-out connection from a slow internet, wireless interference or a weak signal.
- 2160-8028
- The console could not connect to Nintendo's services during a connection test; Nintendo lists the DNS, a slow connection, interference or a weak signal.
Stop boundary
When this stops being a self-service repair
- !If a specific DNS is required by your network, contact the network administrator; do not replace it with a public DNS on a managed network without asking
- !Router firmware updates and factory resets are for the router's maker to guide, so ask them before doing either
- !If the code persists at more than one location, contact Nintendo Support with the code and the connection test results

Sources behind this answer
Where the manufacturer's article stops. These articles all trace back to how the console resolves names and routes traffic: DNS, proxy settings, timeouts and the network beyond the router. They do not cover a wrong password or a missing address. The Google DNS addresses are Nintendo's own suggestion and are subject to Google's terms; any public DNS you trust would do the same test.

Common questions
What does 2110-3129, 2110-3000 through 2110-3999, 2110-3127, 2110-3150, 2122-1006, 2318-0203, 2618-0203, 2318-1200, 2809-1028, 2811-1006, 2160-8028 mean on a Nintendo Switch console?+
the console reached the router but could not resolve or reach Nintendo's servers, which points at the DNS or proxy settings, the internet service, or a timed-out connection
Should I keep Google's DNS after it works?+
That is your choice. Nintendo suggests it as a test that shows whether your current DNS is the problem, and it says the servers are Google's and subject to Google's terms.
What does 2110-3129 mean on a Switch?+
Nintendo says it points at the DNS in use, meaning either an incorrect DNS entered in the console or a problem with the internet provider or DNS service.
Where are the DNS settings on the Switch?+
Open System Settings, Internet, Internet Settings, choose your saved network, then Change Settings and DNS Settings. The screen offers Automatic or Manual.
What MTU value should I use?+
Nintendo recommends leaving the MTU at its default of 1400 for most home networks and changing it only when your provider gives a value.
What does the proxy setting do?+
It routes the console's traffic through a proxy server. Nintendo says to keep it Off unless you actually connect through one, because turning it on without one breaks the connection.
Can a school or office network cause these codes?+
Yes, they often assign a specific DNS or filter devices, and Nintendo tells you to contact the network administrator in that case.
