After investigating this particular issue, it turns out that this problem can occur due to multiple causes. Here’s a shortlist of potential culprits that might be causing this problem:
Method 1: Power Cycle your Console
According to several affected users, this particular error code can also occur due to a glitch caused by a temporary file that your console is currently storing. In this case, you should be able to resolve this problem by going for a soft reset. This operation will successfully clear any temp data along with the power capacitors ensuring that no temporary data can survive in between startups and cause the error code 2110-2003. This operation was confirmed to be successful by several affected users that were previously dealing with the same problem.

Method 2: Rebooting or Resetting your router
In case you see the 2110-2003 error code on your Nintendo Switch console but you’re also encountering similar issues with other devices that are currently connected to your home router, you are likely dealing with a network inconsistency. Fortunately, most occurrences of this kind can be resolved either by a simple reboot or by resetting your router settings back to their default equivalents. If you decide to go for a simple router reboot, keep in mind that this operation will end up refreshing your IP and assigned DNS that your console is using. This doesn’t pose any data loss risk. To perform a router reboot, use the ON/OFF button on your router (typically located on the back). When the router is ON, press it once to turn it off, then disconnect the power cable physically to ensure that the power capacitors are completely drained. Once this time period passed, wait for Internet access to be re-established, then attempt to connect your Nintendo console to your home router again and see if the problem is now resolved. In case the same problem is still resolved, the next course of action should be to go for a router reset. To do this, you’ll need to use the dedicated button on the back. Note: Keep in mind that most manufacturers will make this button built-in so it’s not accidentally pressed. You’ll need a small screwdriver or a similar object to access this button. But in case you want to go for a router reset, keep in mind that this operation will basically revert your router settings back to their default values. This means that any custom settings you’ve established inside your router settings will be lost – This includes forwarded ports, whitelisted items, blocked devices, etc. To initiate a router reset, press and hold on the reset button (back of your router) and keep it pressed for about 10 seconds or until you see the front LEDs flashing all at once. Once you notice this behavior, release the reset button and wait for the connection to be re-established. Once this procedure is complete, re-establish the connection tot the internet and see if the operation is complete. Note: If you’re using PPPoE, you will need to reinsert the login credentials provided by your ISP. Once the internet access is restored, attempt to connect your Nintendo Switch console to the Internet via your router and see if the error code is now resolved. In case you still end up encountering the same 2110-2003 error code, move down to the next potential fix below.
Method 3: Changing the Network Security
In none of the methods above have worked for you, it’s possible that you’re actually dealing with a fairly common bug having to do with the way your Switch console knows how to manage the security method of your Wi-Fi network. This has been an ongoing problem since the console launched back in 2017 and Nintendo still hasn’t managed to push a software update that will eradicate this problem. But the good news is, some users have found a workaround around this problem and is super easy to deploy. As it turns out, you can most likely get this issue resolved by going to the Internet Settings of your Switch console and change the Security technology to something different. Here’s a quick guide on attempting to resolve the 2110-2003 error code by changing the default WI-Fi technology from the Internet Settings menu: In case the same problem is still occurring, move down to the next potential fix below.
Method 4: Switching to Google DNS
If none of the potential fixes below have worked for you, you should start to seriously consider a DNS (Domain Name Address) inconsistency. There are a lot of user reports confirming that making the switch to the DNS range provided by Google was the only thing that allowed them to fix the 2110-2003 error code. In case you suspect that you might actually be dealing with a network inconsistency, follow the instructions below to make the switch to the DNS addresses provided by Google:
