Wi-Fi 2.4 and 5 GHz on Nintendo Switch and Switch 2. Security Both support WPA2-PSK (AES); Switch 2 also supports WPA3-SAE (AES). Models Nintendo Switch, Nintendo Switch Lite, Nintendo Switch OLED Model, Nintendo Switch 2 **Checked 2 November 2026.** Nintendo Switch, Switch Lite, OLED Model and Switch 2 internet guidance, checked November 2026. ## Wi-Fi it needs Nintendo lists 2.4 and 5 GHz support for both generations. Its compatibility lists differ for wireless security and standards. Prefer modern security over WEP. If a network uses a mode your console does not support, ask the network administrator or consult the router manual before changing it. A security change can affect other devices. - **Switch:** WPA-PSK (AES) and WPA2-PSK (AES), plus legacy WEP. Nintendo lists 802.11 b/g/n/ac. - **Switch 2:** WPA-PSK (AES), WPA2-PSK (AES) and WPA3-SAE (AES). Nintendo says WEP is not supported and lists 802.11 a/b/g/n/ac/ax. - **Wired:** the Switch 2 dock has a LAN port. Some original Switch docks need a compatible USB LAN adapter; the OLED dock has a built-in port. **Kilobat can help.** `kilobat scan` lists the networks around your Mac with their band and channel, so you can see whether yours is on 2.4 GHz at all, and `kilobat channels` names the least crowded channel.

Open **System Settings** from the HOME Menu. 2. Select **Internet › Internet Settings**. 3. Choose your network name from the list. 4. Enter the Wi-Fi password if asked. 5. Wait for the connection test and select **OK**. If the network name is greyed out, Nintendo says its security type is not supported by the console. If the name is missing, move closer and press Y to search again. **Kilobat can help.** Once it has joined, Kilobat’s **Tools › Devices** lists it with its address and maker, and [new-device alerts](https://kilobat.app/docs/home-network#new-devices) tell you whenever something new joins your home Wi-Fi. ## How much data it uses Nintendo says a mobile hotspot can be used with Switch, though the connection can vary with signal strength. A hotspot’s data allowance and provider terms are separate from the console’s connection test. Nintendo’s connection FAQs do not give a single data-use figure for game downloads, updates or online play. Check the download size and your connection’s allowance. **Kilobat can help.** Kilobat counts what your Mac sends and receives, app by app, not what other devices use. On a shared or capped connection, its [bandwidth monitor](https://kilobat.app/mac-bandwidth-monitor) and [hotspot data saving](https://kilobat.app/save-hotspot-data) look after the Mac’s share. ## Guest, hotel and dorm Wi-Fi Hotels and dorms may require a sign-in page, register each device, or isolate guests from each other. Ask the network operator for its supported console connection method. A guest network that isolates clients can prevent local discovery without necessarily preventing the console reaching the internet. Test internet access separately from a game’s local-network features. A Nintendo Account is not required simply to connect online, Nintendo says. An account is needed for online play or services such as Nintendo eShop. **Kilobat can help.** `kilobat devices --bonjour` lists the devices your Mac can reach and the services they advertise. If other devices do not appear, client isolation is one possible cause; sleeping devices and discovery settings can also affect results. ## When it won’t connect Use the connection test and its error code to find the relevant Nintendo troubleshooting instructions. 1. Move closer to the router and search for networks again. 2. Check the selected network name and password. 3. If the network is greyed out, check its security against your console’s supported modes. 4. Run the connection test and note any error code. 5. Look up that code in Nintendo Support or ask the network administrator. Changing a router’s security affects other connected devices. Make changes only on a network you manage and use the router’s instructions. **Kilobat can help.** Before you blame the device, Kilobat’s [Why can’t it connect?](https://kilobat.app/guides/recipes/why-cant-it-connect) and `kilobat diagnose` check the Wi-Fi, router, internet and DNS from your Mac. ## When it keeps going offline If a previously working connection drops, determine whether other devices have the same problem and whether it improves nearer the router. 1. Restart the console and test the connection again. 2. Move the console nearer the wireless router. 3. Check another device can use the same network. 4. Try a supported wired connection when docked, if available. 5. Contact the network administrator or provider if no device can connect. Nintendo’s support pages have separate instructions for individual errors; follow the one matching the code shown by the console. **Kilobat can help.** `kilobat health-history` shows whether the router or the internet dropped at the same time, and `kilobat devices --all` marks a device that stopped answering as away. To check the signal where it sits, take your Mac there and use Kilobat’s [radar](https://kilobat.app/guides/recipes/find-better-wifi-spot). ## Questions **Can the original Nintendo Switch use WPA3?** Nintendo’s original Switch compatibility list names WEP, WPA-PSK (AES) and WPA2-PSK (AES), but not WPA3. Switch 2 lists WPA3-SAE (AES). **Can Switch 2 use Ethernet?** Yes. Nintendo says the Switch 2 dock has a built-in LAN port; connect the dock to the router and place the console in the dock. ## Sources - [Nintendo Support: Switch internet connection FAQ](https://en-americas-support.nintendo.com/app/answers/detail/a_id/22268/) - [Nintendo Support: Switch 2 internet connection FAQ](https://en-americas-support.nintendo.com/app/answers/detail/a_id/68179/) - [Nintendo Support: Connect Switch to a wireless network](https://en-americas-support.nintendo.com/app/answers/detail/a_id/22375/) - [Nintendo Support: Connect Switch 2 to the internet](https://en-americas-support.nintendo.com/app/answers/detail/a_id/68460/) - [Nintendo Support: Unsupported network settings](https://en-americas-support.nintendo.com/app/answers/detail/a_id/27644/) Checked on 2 November 2026. ## See your network from your Mac Kilobat is a Mac menu-bar app with a CLI and an MCP server for AI agents. It lists the devices on your Wi-Fi and says when a new one joins, keeps a history of the router’s and the internet’s health, scans nearby channels, and shows which app on your Mac is using the network.
