Why is my Dota 2 so laggy?

Dota 2 connection issues and lag on PC often arise from an unstable internet connection, particularly when using Wi-Fi instead of a wired Ethernet connection.

Bandwidth fluctuations, especially with multiple devices connected to the same network, can lead to delays and disconnections during gameplay.

Additionally, server-related problems, such as maintenance or disruptions on Valve’s servers, can cause temporary connectivity issues.

That’s just a couple of examples of what can cause your Dota 2 to be so laggy, now let’s take a look at how you can fix the lagging problems.

How to fix Dota 2 network errors & connection issues on PC:

Below are the steps for fixing issues with Dota 2 connection problems and network errors, on your Windows 10 or Windows 11 PC or laptop.

Fix 1: Ensure Dota 2 is not being blocked by your firewall

Check that your firewall is not blocking the game from accessing the internet otherwise, you will not be able to connect online in the game.

If you are using Windows Defender Firewall then you can allow Dota 2 access through your firewall by doing the following:

  • Open the Windows Start menu and search and open “Windows Defender Firewall
  • Click “Allow an app or feature through Windows Defender Firewall
  • Make sure that the boxes are ticked next to Dota 2
  • If Dota 2 is not on the list click on “Allow another app” and add it manually

Fix 2: Temporarily disable your security

Disable your computer’s security and see if that fixes the connection issues with Dota 2 (just remember you will not be protected while your security is disabled).

If this works then you will need to add the game to the exception list of your security to prevent future connection issues, while also keeping your PC secure.

Fix 3: Ensure Steam is up to date

  • Open Steam
  • Click on Steam in the top left-hand corner
  • Click on “Check for Steam Client updates
Selecting "check for steam client updates" in Steam
  • If an update is available then it will download and you will need to Restart Steam once finished

  • Make sure that the boxes are ticked next to Steam

Fix 7: Use Cable Not Wi-Fi

It’s a much more stable connection. If you are already using cable then ensure your cable is not damaged.

Fix 8: Check if there are currently any known issues with your internet provider

Check your internet provider’s website for any issues in your area. For example at the time of writing this fixing guide, I am with Virgin Media, so I would need to go onto their website and do a local check on my area and see if any problems have been reported.

Fix 9: Cancel any background programs
