Nintendo Switch Wi-Fi: connect, check security and fix dropouts

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.

Set it up

Nintendo’s setup flow searches nearby Wi-Fi networks, then tests the connection after you enter the password.

1. 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.

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.

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.

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.

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.
