Here are 5 steps to troubleshoot any connection issues:

  1. Check Wi-Fi signal strength: Move closer to your Wi-Fi router ensuring the connection is not unstable.
  2. Test internet speed: Use a reliable tool like SpeedTest.net to measure your internet speed. If the speed is slow or below the recommended requirements for Super Smash Bros. Ultimate, contact your internet service provider to address the issue.
  3. Restart your networking devices: Turn off your Wi-Fi router and cable modem, then wait for a few seconds(20) before turning them back on.
  4. Minimize bandwidth usage: Make sure no other devices or applications on your network are consuming excessive bandwidth while playing Diablo 4.
  5. Consider a wired connection: If possible, connect your gaming device directly to the router using an Ethernet cable. Wired connections tend to be more stable and reliable for online gaming.

If these connection fixes don’t work, you can try resetting your network settings on Windows 11 to potentially address freezing issues.

Solution 2: Call Your ISP

Encountering lagging on your Nintendo Switch can be fixed with this straightforward solution:

  1. Contact Your Internet Service Provider (ISP):
    • Reach out to your ISP for assistance. They have access to data and diagnostics tools that you don’t, which can be crucial in identifying and resolving internet connection issues.
  2. Request to Open Specific Ports:
    • Inform your ISP about the specific ports that need to be opened for optimal Nintendo Switch connectivity. Here’s the list:
      • TCP Ports: 80, 443, 3478, 3479
      • UDP Ports: 3478, 3479, 49152 ~ 65535

These steps are tailored to address the unique requirements of your Nintendo Switch’s network connection, enhancing your gaming experience by potentially resolving stuttering.

Remember, a stable and properly configured internet connection is key to a smooth gaming experience, especially in multiplayer modes.
