Lag can be a real headache for gamers, especially when you’re deep into a game and the action comes to a stuttering halt. Nintendo Switch players experiencing lag in Monster Sanctuary may find it frustrating, as this can impact the enjoyment of their adventure in this monster-filled world. Fortunately, there are several steps that can be taken to address this issue, ranging from checking your internet connection to contacting support for further assistance. In this article, we’ll guide you through the practical solutions designed to help smooth out your gameplay experience and get you back to monster taming with minimal interruption.
Solution 1: Check Your Internet Connection for any Issues
To fix locking up on Monster Sanctuary, it’s important to examine your internet connection.

Here are 5 steps to troubleshoot any connection issues:
- Check Wi-Fi signal strength: Move closer to your Wi-Fi router ensuring the connection is not unstable.
- 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 Monster Sanctuary, contact your internet service provider to address the issue.
- 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.
- Minimize bandwidth usage: Make sure no other devices or applications on your network are consuming excessive bandwidth while playing Diablo 4.
