The new Call of Duty installment, Vanguard, has finally arrived.

But the reactions are mixed. Besides the tactics and designs, many players are reporting issues like constant lag and packet burst. According to some, the enemies disappeared and killed them all of a sudden like in the Matrix.

But don’t worry if you’re on the same boat. These issues might not be so hard to fix at all.

Before you start troubleshooting, first check if all the game servers are up.

Try these fixes:

You might not need to try them all. Simply work down the list until you hit the one that does the trick.

  1. Reboot your network
  2. Use a wired connection
  3. Update your network driver
  4. Change your DNS settings
  5. Use a VPN
  6. Reinstall the game

Fix 1: Reboot your network

The first fix you can try is restart your network equipment. This will reset the connection, clear cache and get you a new IP address. It should do the trick if it’s just a glitch.

  1. At the back of your modem and router, unplug the power cords.

    Router
  2. Wait at least 30 seconds, then plug the cords back in. Make sure the indicators are back to their normal state.
  3. Open your browser and check the connection.
Rebooting might only be a temporary solution. If you’re using an old router, consider upgrading to a better gaming Wi-Fi. Also don’t forget your modem.

Fix 2: Use a wired connection

If you’re a serious gamer, you should be using a wired connection. We can all agree that Wi-Fi is convenient, but it’s hardly ideal for AAA shooters. So if available, use a network cable from reputable brands.

If you’re on Wi-Fi, make sure you’re using the 5 GHz band. You can also test your internet speed on speedtest.net. Normally you’ll need at least 20Mbps for Warzone. And if the result is much lower than the promised speed, contact your ISP to sort this out.

Fix 3: Update your network driver

The constant high ping could indicate a driver issue. In other words, you might be using a broken or outdated network driver. If you don’t know when was the last time you updated your drivers, definitely do it now.

You can update your network driver manually, by visiting the motherboard manufacturer’s website, finding the latest correct installer for your model and installing step by step. But if you’re not comfortable playing with device drivers, you can use Driver Easy to update automatically.

  1. Download and install Driver Easy.
  2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
  3. Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system.
    (This requires the Pro version – you’ll be prompted to upgrade when you click Update All. If you don’t want to pay for the Pro version, you can still download and install all the drivers you need with the free version; you just have to download them one at a time, and manually install them, the normal Windows way.)
The Pro version of Driver Easy comes with full technical support. If you need assistance, please contact Driver Easy’s support team at support@drivereasy.com

After updating all the drivers, restart your PC and check the gameplay in COD: Vanguard.

If the latest network driver doesn’t give you luck, simply take a look at the next fix.

Fix 4: Change your DNS settings

If you don’t know what DNS servers are, they translate domains to the actual IP address. Normally we’re using DNS servers assigned by broadband providers, but you can change them to faster public ones.

  1. At the bottom right corner of your screen, click the computer icon. Then click Network & Internet settings.
  2. Under the Advanced network settings section, click Change adapter options.
  3. Right-click your network adapter, select Properties.
  4. Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
  5. Select Use the following DNS server addresses:. For Preferred DNS server, type 8.8.8.8; and for Alternate DNS server, type 8.8.4.4. Click OK to save the changes.
  6. Next you need to purge the DNS cache for the changes to apply. On your keyboard, press Win (the Windows logo key) and type cmd. Select Run as administrator.
  7. In the pop-up window, type in ipconfig /flushdns. Press Enter.

Once done, restart your Battle.net client and test your game.

If this trick doesn’t work for you, take a look at the next one below.

Fix 5: Use a VPN

If there aren’t any reports of servers being down, it’s likely that the issue is on your end, or it could be a regional issue. Either way, you can give VPN a try.

Usually you don’t need VPNs for gaming, unless you’re having constant packet loss and lag spikes. VPN servers offer a stable and private connection between your PC and the game servers, giving you smooth gameplay even during rush hours. You can use a VPN for the time being, and circle back to troubleshooting when you feel like it.

Here’re some gaming VPNs we recommend:

Fix 6: Reinstall the game

Frankly speaking, this usually has little to do with network issues. But some players reported that they can play normally after a reinstall. If none of the above seem to work for you, you can try this nuclear solution and see how it goes.

If it’s too much hassle for you, first try verifying the game files in the Battle.net client. This will check if there’re files missing or corrupted, and it will download the available updates.


Hopefully this post helps you stop the lag in COD: Vanguard. If you have any questions or ideas, feel free to drop a line and we’ll get back to you.
