Nintendo Switch Won’t Connect to Wi-Fi: Error Codes and Fixes

The Switch is one of the pickier devices on a home network: it supports fewer Wi-Fi security types than a phone, it often sits in a dock behind a TV, and its error messages are just codes. Most connection problems still come down to a few causes — distance, interference, the password, or a router setting. Here is the order to work through them, based on Nintendo’s own troubleshooting.

Quick Fixes First

These steps fix most connection failures, and they cost nothing. Do them in order and test after each one, so you know what actually helped.

1. Restart the console — not just sleep. Hold the POWER button for three seconds, then choose Power Options → Restart.
2. Restart the router and modem. Unplug them, plug them back in, and wait until other devices are online again before testing the Switch.
3. Move the Switch closer. Nintendo recommends testing within 3 to 5 meters (10 to 15 feet) of the router. Take it out of the dock for the test — a dock behind a TV is a poor spot for Wi-Fi.
4. Clear interference. Nintendo lists metal objects and electronics near the console and router: filing cabinets, speakers, power strips, glass and cordless phones. See Wi-Fi interference.
5. Create a new connection. Go to System Settings → Internet → Internet Settings, select your network and enter the password again, exactly, with capitals and symbols.

Then run Test Connection in the Internet settings.

What the Error Codes Mean

If the Switch connects but shows no internet, the problem is beyond Wi-Fi — check other devices and see Wi-Fi connected but no internet.

If the Switch Can’t Find Your Network

When your network does not appear under Networks Found, Nintendo suggests restarting the console, creating a new connection and searching again after each change (press Y to search again). Also check:

• Is the network hidden? The Switch needs the router to broadcast its network name (SSID), or a manual setup with the name typed in — see below and should you hide your Wi-Fi network.
• Does it show up on the other band? If your router uses one name for both bands, give 2.4 GHz and 5 GHz different names and try each; see 2.4 GHz vs 5 GHz and best Wi-Fi channel.
• Battery reset. Nintendo’s last console-side step: set System Settings → Sleep Mode → Auto-Sleep to Never, let the console run until it powers off, charge it with the AC adapter, then search again.

Router Settings the Switch Needs

Nintendo lists the security types the console supports: WEP, WPA-PSK (AES) and WPA2-PSK (AES). If your router uses another type, such as WPA-PSK (TKIP), Nintendo says to change the router’s setting. WPA3 is not on that list, so on a router set to WPA3 only, switch to WPA2/WPA3 mixed mode or WPA2-PSK (AES); see WPA2 vs WPA3. After changing the security type, other devices may need to reconnect.

Other router settings that can block a single device:

• MAC filtering or access control — add the Switch to the allowed list, or turn filtering off.
• Parental controls or device schedules that block the console at certain times; see how to block websites on a router.
• Too many connected devices on an older router.

For playing online, a strict NAT type causes separate problems — see NAT type strict and UPnP.

Set Up the Connection Manually

If the network still does not appear, or it is hidden, add it by hand:

1. System Settings → Internet → Internet Settings.
2. Scroll to the bottom of Networks Found and choose Manual Setup.
3. Enter the SSID (network name) exactly, the security type and password; leave IP address and DNS on Automatic unless you have a reason to change them.
4. Set Connect to Hidden Network to On if the network is hidden.
5. Select Save, then Connect to This Network.

A wired connection avoids Wi-Fi problems entirely: a dock with a LAN port, or a USB LAN adapter, lets the Switch use an Ethernet cable — see Ethernet vs Wi-Fi.

Still Not Working

Nintendo’s remaining steps point to the router: update its firmware or reset it to factory defaults, following the router maker’s instructions — see how to update router firmware. To rule out the console, try connecting at a friend’s home or to a phone hotspot. If the Switch connects there, the problem is your router or network; if it cannot find any network anywhere, contact Nintendo support.
