What is Network Latency in Diablo 4?

Before we dive into how to fix network latency issues in Diablo 4, let’s first understand what network latency is. Network latency is a delay that occurs when your computer sends a request to the game server and waits for the server’s response. This delay can cause lag, stuttering, and other issues that can significantly affect your gaming experience.

A slow or unstable internet connection can cause network latency issues. You can check your internet connection speed by using online tools like or

Close Other Programs

If you’re running multiple programs or applications in the background while playing Diablo 4, they may be using up your network bandwidth and causing network latency issues. Close any unnecessary programs and applications that are running in the background to improve your internet connection’s performance.

Disable Firewall or Antivirus Software

Your firewall or antivirus software may be blocking Diablo 4 from accessing the internet, causing network latency issues. Temporarily disable your firewall or antivirus software and see if the issue is resolved. If this is the case, add Diablo 4 to the software’s list of exceptions or whitelist to prevent it from being blocked in the future.

Change Your DNS Server

Sometimes changing your DNS server can improve your internet connection’s performance and reduce network latency issues. Your ISP’s default DNS server may not be the most efficient, and switching to a different DNS server can improve your connection’s speed. Google DNS and Cloudflare DNS are two popular and reliable DNS servers you can try.

Use a Wired Connection

If you’re using a wireless connection to play Diablo 4, try switching to a wired connection instead. A wired connection is generally more stable and reliable than a wireless connection, and it can significantly reduce network latency issues.
