On the covered Nintendo Switch console, 2110-2900 through 2110-2999, 2110-2979 means the console did not get a usable IP address: the router's DHCP is off or not answering, or the address the console holds clashes with another device First, power cycle the modem and router so DHCP restarts, then reconnect.
Differential
Likely causes of “Nintendo Switch console code 2110-2900 through 2110-2999, 2110-2979”, and how to tell them apart
- 1
The router's DHCP server is switched off or not responding
What separates it The console joins the Wi-Fi but never gets an address, and a new device on the same router also fails to get online
How to confirm Power cycle the modem and router and reconnect; if a restart does not restore addresses, check the router's DHCP setting with the router's maker
- 2
An address clash with another device on the network
What separates it The code is 2110-2979, or the problem began after you typed a fixed address on the console
How to confirm Compare the console's IP address in its connection settings with the address list on the router or another device
- 3
A weak wireless link that drops the address request
What separates it The console is far from the router or in the dock, and the code comes and goes
How to confirm Move within 10 to 15 feet, out of the dock, and move metal objects and electronics away as Nintendo's article says
- 4
Interference from a Bluetooth audio device on 2.4 GHz
What separates it The code appears only while a Bluetooth headset or speaker is paired
How to confirm Disconnect the audio device or connect to the 5 GHz band; Nintendo says some devices interfere with 2.4 GHz
Before you touch a setting
Record this first — changing settings destroys the evidence
- The exact code out of the 2110-2900 to 2110-2999 range, or 2110-2963 or 2110-2979
- Whether the IP address setting on the console is Automatic or Manual, and what address it shows
- Whether other devices on the same router receive addresses normally
- Whether the console is connected by Wi-Fi or by Ethernet, and which console model it is

0 of 8 completedWhat to do first
Reversiblepower cycle the modem and router so DHCP restarts, then reconnect.
Correct only the documented fault domain
ReversibleIf a restart does not hand the console an address, set the IP address by hand: copy the address, subnet mask and gateway from another device, add 20 to the last number of the address, and enter all three under IP Address Settings.
Power cycle the home network
ReversibleUnplug the power cable from both the modem and the router, wait 30 seconds, plug the modem back in and wait for steady lights, then plug in the router. If the modem's lights stay on after unplugging, it has a backup battery that must be removed for a true power cycle.
Set the address by hand only if a restart fails
ReversibleOn another device, note the IP address, subnet mask and gateway. On the console open Internet Settings, choose Change Settings, then IP Address Settings and Manual, hold B to clear the zeros and enter the values.
Follow Nintendo's rule for choosing the address
ReversibleEnter the address you found on another device but add 20 to the last group of digits: Nintendo's example turns 192.168.2.5 into 192.168.2.25. The subnet mask on most networks is 255.255.255.000, and the gateway must be entered as your network shows it.
Check for a clash
ReversibleEvery device must have a unique address. If 2110-2979 appears, choose another valid address and confirm it is not already assigned to a console, PC or laptop on the network.
Improve the wireless link
ReversibleBring the console within 10 to 15 feet of the router, take it out of the dock and move metal objects, speakers, power strips, glass and cordless phones away from the console and router.
Involve the router's maker last
ReversibleIf the console still gets no address, update the router's firmware and, if the maker agrees, restore factory defaults, then re-enter the Wi-Fi password on every device. Nintendo does not guide these steps.
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.
- 2110-2900 through 2110-2999
- A general range (2110-2900 to 2110-2999): the console could not obtain an IP address, often because the router's DHCP server is off or the router is not responding; Nintendo has wireless and wired branches.
- 2110-2979
- An IP address conflict: the console was given an address that another device on the network already uses, such as another console, a PC or a laptop.
Stop boundary
When this stops being a self-service repair
- !Every device on a network must have a different IP address, so never copy another device's address exactly when you set one by hand
- !Router DHCP settings and factory resets belong to the router's maker or your internet provider, so contact them before changing those
- !If the console still gets no address on other networks too, contact Nintendo Support with the code and the connection test result

Sources behind this answer
Where the manufacturer's article stops. These articles cover the step after the console joins the router, when it should receive an IP address. They do not cover a wrong password (2110-2xxx) or a DNS fault (2110-3xxx). The manual address example is Nintendo's and assumes a typical home network; a network with an unusual subnet needs its own values.
Exact questions
Common questions
What does 2110-2900 through 2110-2999, 2110-2979 mean on a Nintendo Switch console?+
the console did not get a usable IP address: the router's DHCP is off or not answering, or the address the console holds clashes with another device
What does the 2110-2900 to 2110-2999 range mean?+
Nintendo says these errors happen when the console tries to obtain an IP address from the network, for example because the router's DHCP server is off or the router is not responding correctly.
What address should I type on the Switch?+
Take an address from another device and add 20 to its last number, as Nintendo's article does, then copy that device's subnet mask and gateway exactly.
Is 255.255.255.000 always the subnet mask?+
Nintendo says it is the mask for most networks, but read yours from a device on the network rather than assuming, because a different mask means a different setup.
Why does Nintendo say to power cycle first?+
Restarting the modem and router restarts the DHCP server that hands out addresses, which clears most cases before any manual settings are needed.
Does this apply to both Switch and Switch 2?+
Yes, the articles give the same steps for both consoles, with separate screens described for each and separate wireless and wired branches.
