To fix Nintendo Switch Error 2618-0513, try matchmaking again, restart your Nintendo Switch and router, test a different internet connection, and check your NAT type. The error usually occurs when your network cannot establish a reliable peer-to-peer connection with another console.
Trying to join an online match only to see Nintendo Switch Error 2618-0513 can be frustrating, especially when your console appears connected to the internet. This error usually appears when your Nintendo Switch cannot complete the peer-to-peer connection needed to connect with another player or console.
The good news is that this does not automatically mean your Nintendo Switch is damaged. The problem is usually related to the network environment, internet service provider, connection type, or NAT configuration. By testing your connection in the right order, you can identify the likely cause without randomly changing advanced router settings.
Why This Problem Happens
Nintendo Switch Error 2618-0513 usually means your network is not optimal for the peer-to-peer connection required for online matchmaking. Nintendo identifies possible causes including your internet service provider, connection conditions, and the NAT type of your network.
Think of NAT as a traffic controller between your Nintendo Switch and other devices online. Your console may connect to the internet successfully while still having trouble communicating directly with another player’s console.
That is why you may browse the internet, download games, and stream videos without problems while online matchmaking fails.
Different online activities use networks differently. Streaming usually involves receiving data from a central server. Multiplayer gaming may require your console to communicate with another player’s console through a connection that your network restricts.
Certain mobile hotspots and 5G networks can also make peer-to-peer connections more difficult. Android users can follow Google’s official hotspot and tethering guidance when testing a different connection.
The key question is not simply whether your Switch has internet access. The real question is whether your network can establish the type of connection required for the specific online match.
How to Fix Step by Step
Step 1: Retry the matchmaking process
Start by trying to join the online match again.
Close the failed matchmaking attempt, return to the game’s online menu, and try connecting again. If the error appeared only once, a temporary interruption may have prevented the connection from completing.
When two consoles connect for online multiplayer, the matchmaking process must successfully establish communication between the players. A brief interruption can cause the attempt to fail even when your internet connection is otherwise working.
Why this works: Retrying gives the matchmaking process another opportunity to establish the connection.
If the error appears repeatedly, do not keep reopening the same menu indefinitely. Repeated failures usually mean the connection needs to be refreshed or investigated further.
Step 2: Restart your Switch and network equipment
Restart your Nintendo Switch and the equipment providing your internet connection.
First, completely restart the Switch. Then restart your router or modem. If your connection uses separate modem and router devices, restart both according to the manufacturer’s instructions.
Wait until the internet connection is fully restored before testing online matchmaking again.
A restart can clear temporary connection problems and refresh the network session between your console, router, and internet service provider.
Why this works: Network equipment can occasionally remain in a problematic connection state. Restarting it creates a fresh connection path.
Pro Tip: Do not test the game while your router is still reconnecting. Wait until another device can browse the internet normally, then test the Switch.
If you need to test a Windows computer as an alternative connection source, Microsoft’s official mobile hotspot instructions explain how to share an available connection.
Step 3: Test a different internet connection
Connect your Nintendo Switch to another available internet connection and try the same online matchmaking process.
You could test another home network or a compatible mobile hotspot. The purpose is not necessarily to use that connection permanently. It is a diagnostic test.
If matchmaking works on the second network, your Nintendo Switch is probably not the main problem. Your original router, ISP, NAT environment, or network configuration becomes the more likely cause.
If the error appears on multiple networks, the problem may require further investigation.
A failed mobile hotspot test also does not automatically prove that your Switch is faulty. Some mobile and 5G networks have their own restrictions that can affect peer-to-peer multiplayer connections.
Why this works: Comparing networks helps separate a console problem from a network problem.
This is one of the most useful troubleshooting tests because it prevents you from changing router settings unnecessarily. If the error disappears on another connection, you have valuable evidence that the original network is the problem.
If you can connect successfully on another network but not your usual connection, contact your internet provider for further help. The problem may be related to the network environment or router rather than the console itself.
Step 4: Check your NAT type and improve the network connection
On your Nintendo Switch, open:
System Settings > Internet > Test Connection
Review the connection results, especially the NAT Type.
The NAT result gives you an indication of how easily your console can communicate with other devices online. In general, a more open NAT environment makes peer-to-peer communication easier, while a restrictive NAT environment can prevent some connections from being established.
As a general guide:
- NAT Type A: Generally offers the fewest connection restrictions
- NAT Type B: Usually suitable for online multiplayer
- NAT Type C: May cause some connection limitations
- NAT Type D: More restrictive and may cause connection problems
- NAT Type F: Highly restrictive and may prevent some online connections
These results are useful clues rather than a guarantee that every game will behave identically. A particular game may still experience connection problems because of its own matchmaking system or the network environment of another player.
If your NAT result is restrictive, avoid randomly changing advanced router settings. First, check whether the error affects one game or multiple online games. Also compare the result with another network if possible.
If the problem is limited to your home network, contact your internet provider if the network appears to impose restrictions that cannot be changed through your Switch or router.
If you use a supported TP-Link router, check the manufacturer’s official firmware update guidance before installing an update. Always confirm the exact model and hardware version first.
Why this works: Checking the NAT result helps identify whether your network is restricting the type of communication required for online multiplayer.
What Most Users Don’t Realize
A fast internet connection does not automatically guarantee successful online matchmaking. Download speed is only one part of the connection.
Your network can be fast enough for streaming and downloads while still having difficulty establishing a direct connection with another player’s console.
Nintendo Switch Error 2618-0513 can also affect connections to specific players. If you can play with some people but not another player, the network environment on either side may be affecting the connection.
That is why testing another network is so valuable. It helps determine whether the problem follows your Nintendo Switch or stays with the network.
Useful Official Resources
For the specific error, Nintendo’s official support information for Error Code 2618-0513 is the most relevant source. It explains that the error is associated with problems completing peer-to-peer matchmaking and can involve the ISP, internet connection, or NAT type.
Android users can follow Google’s official hotspot and tethering instructions when testing another network. Windows users can use Microsoft’s mobile hotspot guidance to share an available connection.
If your router requires a firmware update, consult the manufacturer’s official support documentation before installing anything. For supported TP-Link devices, follow the correct model-specific instructions rather than installing firmware intended for another router.
Quick Fix Checklist
- Retry the online matchmaking process
- Restart the Nintendo Switch and router
- Test another internet connection
- Check the Switch NAT type
- Confirm compatible router firmware is current
- Contact your ISP if the network remains restricted
Common Mistakes Users Make
One common mistake is repeatedly restarting the game without testing the network. If the network cannot establish the required peer-to-peer connection, reopening the game alone may not solve the problem.
Another mistake is assuming that fast download speeds guarantee successful matchmaking. Online multiplayer can also depend on latency, NAT behaviour, network restrictions, and communication with other players.
Some users change advanced router settings randomly. This can create new problems and make the original issue harder to diagnose. Test one change at a time instead.
Another mistake is assuming that a mobile hotspot will always fix the issue. Some mobile and 5G networks can also restrict peer-to-peer connections.
Nintendo Switch Error 2618-0513 should therefore be approached through testing rather than guesswork. Compare networks, check the NAT result, and avoid changing settings you do not understand.
Extra Tips to Prevent the Issue
Keep your router firmware updated when the manufacturer provides a compatible update. Updates can improve network stability and address known problems.
Keep the Nintendo Switch reasonably close to your wireless router when using Wi-Fi. Reducing distance and interference can help create a more stable connection during online play.
Avoid placing the router behind thick objects or near devices that may interfere with the wireless signal. If possible, position the router in an open location rather than inside a cabinet or behind large obstacles.
Restarting your router occasionally can clear temporary network problems. However, if you constantly need to restart it, investigate the underlying connection instead.
For security, use a strong Wi-Fi password and keep your router software current. Do not disable important security features or expose your network unnecessarily just to force a particular NAT result.
If you install router firmware, verify the exact model and hardware version first. Incorrect firmware can cause additional problems.
These maintenance, stability, and security habits can help reduce recurring Nintendo Switch Error 2618-0513 problems while keeping your home network safer and more reliable.
In Summary
Nintendo Switch Error 2618-0513 is usually a network communication problem affecting peer-to-peer matchmaking. The best troubleshooting approach is to retry the connection, restart your network equipment, test another internet connection, and check your NAT type.
If the Nintendo Switch works correctly on another network, focus on the original router or ISP. If the error continues across different networks, further console and network troubleshooting may be necessary.
