      • Hold the POWER Button down for three seconds, then select Power Options, followed by Restart.
    • Create a new internet connection.
      • Set up a new internet connection, ensuring that you are attempting to connect to the correct network and that you are receiving a strong wireless signal from the network.

      • Restarting your network devices may resolve this issue if it is related to the devices being unresponsive.
    • Move the Nintendo Switch console closer to the wireless router.
      • If possible, place the Nintendo Switch console within 3 to 4.5 metres of the wireless router to improve the signal strength during troubleshooting.
        • It may be helpful to remove the Nintendo Switch console from the Nintendo Switch dock while troubleshooting, then return the console when troubleshooting is complete.
    • Move any metal objects or electronic devices away from your Nintendo Switch console and wireless router.

    • If supported by your router, connect to a different wireless band.
      • Many routers support both the 2.4Ghz and 5Ghz frequency bands. If your router supports both, set up a new internet connection and connect to the band you are not currently connecting to. Many routers will have default SSID names that label whether the connection is 2.4Ghz or 5Ghz, but if you're not sure, contact your internet service provider for assistance with how you can review this information within your router's settings.
