So, whether you're a seasoned Dota 2 veteran or a newcomer to the game, our guide will equip you with the knowledge to conquer network issues and enhance your gaming experience. Let's dive in and tackle those network challenges together!

Optimize your Dota 2 In-Game Settings

Begin by launching Dota 2 and heading to the settings menu. Ensure you access the Advanced Options tab within the Options section to make necessary adjustments. Here, you should enable the "I have a Low-End Network" option, which is particularly beneficial for players with slower internet connections or limited bandwidth. This setting helps optimize network performance and reduces the chances of experiencing lag.

Additionally, on the right-hand side of the Advanced Options tab, enable the "Display Network Information" setting. By activating this feature, you'll be able to view your current latency to the server and other vital network statistics in real-time during gameplay. This valuable information can help you pinpoint the root cause of any network-related issues and take appropriate action to resolve them. With these optimized settings, you'll be well on your way to a smoother, more enjoyable Dota 2 experience.

Check the Dota 2 Server Status for Potential Issues

When encountering high server-side latency, it's essential to consider that the issue might not be on your end, but rather with the server you're playing on. To verify whether the servers are functioning correctly, you can visit a dedicated website that tracks the status of various online services.

To perform this check, open your web browser and navigate to https://downdetector.com/status/dota-2/. This reliable resource provides real-time information on Dota 2 server performance, outages, and maintenance periods. By monitoring the server status, you can determine if the latency problems are widespread or isolated to your connection. In some cases, you might discover that the developers are aware of the issue and working on a fix, or you could find alternative servers with better performance. Keeping an eye on Dota 2 server status is a crucial step in addressing network lag, high ping, and packet loss issues.

Verify the Integrity of the Dota 2 Game Files

Make sure that your game files are up to date and complete. In your Steam library, right-click the application and select Properties. A new window will open up, where you will have to select Verify integrity of game files in the Local Files tab. This will take a minute to redownload and replace any missing or corrupted game files.

Steam Library > Dota 2 > Properties > Local Files

Test and Improve your Internet Connection

Click here to test your connection. Using Speed-Test services to preview the approximate up- & download speed of your connection, as well as the latency to their server can help a lot in figuring out if network related issues are caused by your own connection or by the server you’re trying to connect to. On www.speedtest.net, make sure that your latency (ping) is averaging out below 100 ms. A connection with a high latency will induce packet loss to the server and will in turn create lag and rubber banding while in-game

To improve your network connection, make sure to use an ethernet cable to connect to your PC. In case you are forced to use a wireless connection, then make sure to restart your router (or modem) if you haven’t done this in a while and reduce the amount of devices connected to the same network.

End Network-Intensive Processes from Running

Access your Resource Monitor by opening up your Task Manager. Right-click your taskbar to open up your task manager. Under Performance select Open Resource Monitor. On the new resource monitor window, open the Network tab, where you will have to open the Processes with network activity.

After a few seconds you will see every process using your network connection on your system. This might be your browser running in the background, steam or a download bottlenecking your connection. I suggest you only end the processes which you know won't break your operating system. In the tab below, you can also preview your network utilization in percent.

Command Prompt

Open up your command prompt by searching for CMD in your taskbar search. The next two commands will help you test and improve your latency and packet loss in case your connection is inducing any.

ping google.com

This command will simply check your latency and packet loss to Google’s servers. You can also ping another server, but the ping google.com command has become somewhat of a benchmark in the recent years.

ipconfig /flushdns

This command will reset your network connection by flushing it’s DNS resolver cache. This command will in any case help improve your latency issues.

Change DNS Server Addresses

Network related issues can be caused by your DNS server address connection. In this step, we will change it, as it should help a lot of users with network problems. Use the shortcut Windows Key + R, and in the dialogue box enter Control and hit enter.

This will open up your control center. From there, navigate to Network & Internet, Network & Sharing Center, and here select your connection. Navigate to Properties and lastly, double-click the Internet Protocol Version 4 as you can preview on the screenshot below. Select to Use the following DNS server addresses option, and as your preferred DNS server, use : 8.8.8.8 and as you alternate DNS server, use: 8.8.4.4. These are the official public DNS server addresses from Google, which are safe to use.

Remove Malware & Unused Applications

We suggest removing malware and prevent applications from running which could use up your available resources or change your game files. For example: Discord, CCleaner, Adobe Applications, Shadowplay and OBS.

Verify Connection to ISP

In case you still experience latency or lag issues then make sure to verify your connection to your Internet Service Provider. You can troubleshoot this step by changing your connection to your personal hotspot for example.

Delete Temporary Files

If you have issues loading maps or downloading other content, then make sure to delete your temporary files. Search for %temp% in your taskbar search to open up your temporary files folder. You can safely delete everything in the folder, some files might remain so just leave them there. This can help you reduce some clutter on your hard-drive.
