To play Mario Kart World online, you need a Nintendo Switch 2, the game, an internet connection, a Nintendo Account, and a Nintendo Switch Online membership. Install the current game update first, and make sure every player uses the same software version. A wired Ethernet setup is not required for ordinary online racing.
Online-play requirements at a glance
| Requirement | What it means |
|---|---|
| Nintendo Switch 2 | Mario Kart World is a Nintendo Switch 2 game; it is not a Nintendo Switch title. |
| A copy of Mario Kart World | Each participating setup needs access to the game. Nintendo’s published requirements do not describe a game-sharing exception. |
| Internet access | Wi-Fi is sufficient for normal online features. Nintendo does not state that an Ethernet cable is mandatory for ordinary online play. |
| Nintendo Account | Your player profile must be associated with a Nintendo Account for the game’s online services. |
| Nintendo Switch Online membership | The paid service membership is required for the game’s online features. |
| Current game software | Install the update required for internet features. Players joining one another must be on the same software version. |
Nintendo summarizes the service requirement on its official multiplayer page: “Internet, Nintendo Switch Online membership and Nintendo Account required for online features, including GameChat.” The same page documents online races for up to 24 players. See Nintendo’s Mario Kart World multiplayer guide for the current feature list.

What “online” includes in Mario Kart World
Online play connects your Switch 2 to Nintendo’s service so you can race with people who are not in the same room. Nintendo lists capacity of up to 24 players for online play and says players can drive together in Free Roam while waiting for the next race. That is different from putting several players on one console or linking nearby consoles over a local network.
Recommended Free Tools
The online membership requirement applies to internet features. It should not be confused with every multiplayer option in the game: some local modes do not use Nintendo’s online service and therefore do not automatically require a paid membership.

Update the game before trying to connect
Nintendo’s support page records a software update released on June 30, 2026 and says the update must be installed to use the game’s internet features. Because later updates may replace that release, check the current Mario Kart World update instructions before you troubleshoot a connection problem.
- Connect the Switch 2 to the internet.
- From the HOME Menu, highlight Mario Kart World, press the + button, choose Software Update, and select Via the Internet.
- Let the download and installation finish, then restart the game if the console asks you to.
- Have every player perform the same check. Nintendo says players must have the same software version to play together; one unupdated console can prevent a group from joining.
If the console reports that no update is available, that means it has checked Nintendo’s servers and found the newest version offered to that system at that moment. It does not remove the requirement that all players match versions.
Do you need Nintendo Switch Online?
Yes. A Nintendo Switch Online membership is required for Mario Kart World’s online features. Internet access and a Nintendo Account are separate requirements: having a broadband connection or signing into an account does not substitute for the membership. Nintendo’s Nintendo Switch Online Service FAQ confirms that online-service games require a membership and identifies internet access and a Nintendo Account as part of the setup.

Rank #2
- The next evolution of Nintendo Switch
- One system, three play modes: TV, Tabletop, and Handheld
- Larger, vivid, 7.9” LCD touch screen with support for HDR and up to 120 fps
- Race from one course to another through interconnected paths that span the world
- Traverse mountains, forests, cities, and more—with shifting weather patterns and a day/night cycle
The membership requirement is for playing over the internet. If you only use a local mode such as same-console multiplayer, Wireless Play, or a wired LAN arrangement, do not assume that the online-service requirement applies in exactly the same way; those modes use different connections described below.
Wi-Fi versus Ethernet: what ordinary online play needs
For normal online racing, Nintendo specifies internet access but does not require a wired connection. A Switch 2 connected to a suitable Wi-Fi network can use the online features. An Ethernet cable becomes relevant when you deliberately choose Nintendo’s wired LAN mode, which is a local-network option rather than a requirement for internet matchmaking.
Using a cable can be useful in a home network that has unreliable wireless coverage, but the game’s published requirements do not establish a performance guarantee or a mandatory speed. Do not buy LAN equipment merely because you want to race online with distant players.

Choose the multiplayer mode that matches your setup
| Mode | Where players are | Player capacity stated by Nintendo | Network and hardware needs |
|---|---|---|---|
| Online Play | Players connect over the internet, whether nearby or far away. | Up to 24 players | Switch 2, game, internet access, Nintendo Account, Nintendo Switch Online membership, and matching software versions. |
| Same-console multiplayer | Players share one Switch 2. | 2–4 players on one system | One console and local controllers; no internet-service membership is identified as a requirement for this mode. |
| Wireless Play | Players use nearby Switch systems over a local wireless connection. | Not stated on the cited instructions | Separate nearby systems and the game; Nintendo’s instructions do not state that wired Ethernet equipment is needed. |
| LAN Play | Players use a wired local network. | 2–24 players, with up to two players per console | Docked Switch 2 consoles, Ethernet cables, a wired router, displays, and possibly a network switch depending on the number of consoles. |
The capacities and mode descriptions come from Nintendo’s multiplayer instructions. The “not stated” entry for Wireless Play reflects what Nintendo identifies in that guidance; it is not a claim that every possible local configuration has the same limit.
How to get into an online race
- Prepare the console. Turn on the Switch 2, connect it to the internet, and confirm that the system can reach Nintendo’s online services.
- Confirm the player account. Use the Nintendo Account associated with the player profile that will enter the online mode.
- Verify membership. Check that the account has an active Nintendo Switch Online membership. If the service has expired, internet matchmaking will remain unavailable even though other internet applications may work.
- Update the software. Use the HOME Menu update command described above and repeat it on every console in the group.
- Launch the game. Open Mario Kart World and select its online option. The exact on-screen arrangement can change with software updates, so follow the labels currently shown by the game.
- Join or create the session. Choose the online race or room option appropriate to your group, then invite or join the other players using the game’s displayed instructions.
- Check the version if someone cannot join. Close the game on all consoles and run the software-update check again. A version mismatch is a documented reason players cannot play together.
Nintendo’s public requirements establish the account, membership, internet, and version checks; they do not require a particular router brand, Ethernet speed, or camera for a standard race.
What you need for wired LAN Play
LAN Play is for people bringing multiple consoles onto the same wired network. Nintendo lists the following equipment:
Rank #4
- Race from one course to another through interconnected paths that span the world
- Traverse mountains, forests, cities, and more—with shifting weather patterns and a day/night cycle
- Ride on rails, jump off walls, skim across water, and more as you race for the finish line
- Take on the adrenaline-packed Knockout Tour—a fierce 24-driver elimination mode
- A Nintendo Switch 2 console and dock for each participating system
- A copy of Mario Kart World
- An Ethernet cable for each wired console connection
- A television or monitor for each docked system
- A wired router
- A networking switch if the router does not provide enough wired ports for the number of consoles
Nintendo specifically says the Switch 2 must be docked to use wired connectivity. LAN Play supports 2–24 players, with up to two players per console. The exact number of cables and available router or switch ports depends on how many consoles you connect, so count ports before setting up the room.
This arrangement does not turn LAN Play into internet matchmaking. It is a separate local mode. If your goal is to race friends who are elsewhere, use Online Play with internet access and Nintendo Switch Online instead of purchasing the LAN equipment listed here.
Optional accessories that are not prerequisites
USB camera
Nintendo’s game page mentions a compatible USB camera for video features. A camera is optional and is not needed to enter an online race. Do not treat video features as part of the basic online checklist.
Best Value
- A variety of playable characters are available, some with unique attributes that affect gameplay and platforming physics.
- Younger and less-experienced players will love playing as Toadette, who is brand new to both games, and Nabbit, who was formerly only playable in New Super Luigi U. Both characters offer extra assistance during play.
- Multiplayer sessions are even more fun, frantic, and exciting thanks to entertaining character interactions. Need a boost? Try jumping off a teammate’s head or getting a teammate to throw you.
- Features a wealth of help features, like a Hints gallery, reference videos, and a Super Guide in New Super Mario Bros. U that can complete levels for you if they’re giving you trouble.
- Three additional modes—Boost Rush, Challenges, and Coin Battle—mix up gameplay and add replayability, while also upping the difficulty for players who want to try something harder. Players can use their Mii characters in these modes.
Joy-Con 2 Wheel
The Joy-Con 2 Wheel is an optional controller accessory. It can change how a player holds the controller, but it is not required for online access, a Nintendo Account, or Nintendo Switch Online.
Ethernet accessories
Ethernet cables, a wired router, and possibly a network switch belong to the LAN Play setup. They are not mandatory purchases for a Switch 2 that will use Wi-Fi for ordinary online play.
Troubleshooting common setup failures
The game says online features are unavailable
- Check that the Switch 2 is connected to the internet.
- Confirm that the player profile is linked to a Nintendo Account.
- Verify that the Nintendo Switch Online membership is active.
- Run the game’s software-update check. Nintendo requires the update for internet features.
One friend cannot join the room
Have every participant compare software versions. Nintendo requires everyone playing together to use the same version. The fastest correction is to close the game on each console, check for updates, install any offered update, and then create the room again.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesYou bought an Ethernet cable but online play still does not work
A cable by itself does not satisfy the account, membership, update, or internet requirements. For standard Online Play, start with the console’s internet connection and service membership. If you intended to use LAN Play, make sure each Switch 2 is docked and that the cables run to a wired router or to a router-and-switch combination with enough ports.
You are trying to play with one console and several people
Use same-console multiplayer rather than Online Play. Nintendo lists 2–4 players on one system. This is a local mode and has different requirements from internet racing.
Final checklist before race day
- Every player has access to a Nintendo Switch 2 and Mario Kart World.
- The consoles can reach the internet when using Online Play.
- Each online player uses a Nintendo Account.
- The required Nintendo Switch Online membership is active.
- The game is updated, including the June 30, 2026 update requirement noted by Nintendo or any newer update that supersedes it.
- All players run the same software version.
- You have not confused optional LAN equipment or accessories with the requirements for ordinary online racing.
With those checks complete, Wi-Fi is enough for standard online play. Reserve docks, Ethernet cables, a wired router, and possibly a network switch for the separate LAN Play setup.
