You are unable to connect your Nintendo Switch console to a wired or wireless network and you receive an error code between 2110-3000 and 2110-3999.
Important: This article is for a general range of error codes. Prior to using the following steps, ensure you have searched the correct error code, and that there is no article specific to that error code.
Important: Test your connection after any changes are made to the Nintendo Switch console or network environment to determine if the change resolves your issue.
Error codes in this range generally indicate an error occurred when the Nintendo Switch console attempted to initially connect to a wired or wireless router (usually prior to obtaining an IP address).
This may occur if the Internet settings were set up incorrectly, or if the Nintendo Switch console could not locate the wired or wireless router.
Ensure other devices on the network have access to the Internet.
Try to connect online through the network with a device that has an Internet browser, and test to ensure you are able to browse the Internet. If other devices cannot connect online, the network itself may not have access to the Internet. If this occurs, contact your ISP or network administrator.
Check the DNS settings within the console's Internet settings.
Access the settings for your saved Internet connection, and review the DNS settings.
If this setting is set to manual, but is not required for your network, change this setting to "Automatic."
If you are required to use a specific DNS address due to the type of network you are using, please contact the administrator for the network you are attempting to use.
Power cycle your home network.
Restarting your network devices may resolve this issue if it is related to the devices being unresponsive.
Manually enter an alternate DNS.
If the DNS you are attempting to use is not working, entering an alternate DNS may resolve this issue.
Try again at a later time.
If this error is due to an issue with your Internet service, you may need to wait a while and try again at a later time.
Move the Nintendo Switch console closer to the wireless router.
If possible, place the Nintendo Switch within 3 to 5 meters of the wireless router to improve the signal strength during troubleshooting.
It may be helpful to remove the Nintendo Switch console from the Nintendo Switch dock while troubleshooting, and then return the console when troubleshooting is complete.
Move any metal objects or electronic devices away from your Nintendo Switch console and wireless router.
Metal objects and electronic devices may interfere with wireless signals. If you have any of these, such as filing cabinets, speakers, power strips, glass, or cordless phones, next to your console or wireless router, move them away.
Situation Not Resolved:
If you are still unable to connect, this may indicate an issue related to the network environment or router being used.
If you would like to continue troubleshooting potential issues related to the router, contact the router's manufacturer for assistance with performing the following steps:
Updating the router's firmware
Resetting the router back to its factory default settings
