Warzone Packet loss in Call of Duty can be immensely frustrating, so how do you fix it? In a game that relies on quick thinking and rapid reactions, packet loss can make the difference between winning and taking a bullet to the head. Warzone packet loss can manifest in a variety of ways. Problems like stuttering, high ping, rubber banding, or even being booted out of a match, are all potential indicators of packet loss.

With several other issues such as Warzone Shadow Bans and Warzone Error Code Diver also impacting the latest Warzone Pacific update, suffering from packet loss may be the tip of the iceberg when it comes to trying to play Warzone.

So we'll discuss today what your options are when you are suffering from potential packet loss on Call of Duty, and how you can try to mitigate it.

How to fix Warzone Packet Loss in Call of Duty

With Warzone packet loss, there is not always an obvious cause for it. With some errors like the Warzone Dev Error, there is a specific cause, and therefore a specific solution. But packet loss can be caused by a wide variety of factors. As such, it means there are a few different potential fixes. While not guaranteed to work, these top tips have the best possible chance of succeeding:

  • Use a wired connection. Put simply, the more stable your internet connection, the better. A wired connection will almost invariably be more stable than a wireless connection.
  • Try a VPN. A common cause of packet loss is network congestion, so if your local server is particularly busy, a VPN may help. This will allow you to connect to a server in a different region, which might be experiencing less traffic.
  • To get the most reliable network connection, set your NAT type to Open or Type 1. Activision says, Open/Type 1 NAT will provide the best connection quality. So if you have a NAT setting of Moderate/Type 2, or Strict/Type 3, then port forwarding can help. To do this:
    • Type in your routers IP address into your browser
    • Log in to your router
    • Find your router’s Port Forwarding section
    • Put the IP address of your PC or console in the correct box in your router
    • Enter the correct TCP and UDP ports for your game in the corresponding boxes. These are as follows:
      • PC: TCP: 3074,27014-27050
      • UDP: 3074,3478,4379-4380,27000-27031,27036
      • PlayStation 4: TCP: 1935,3478-3480
      • UDP: 3074,3478-3479
      • Xbox One: TCP: 3074
      • UDP: 88,500,3074-3075,3544,4500
      • PlayStation 5: TCP: 1935,3478-3480
      • UDP: 3074,3478-3479
      • Xbox Series X|S: TCP: 3074
      • UDP: 88,500,3074-3075,3544,4500
  • In addition to these fixes, you can carry out some other basic troubleshooting checks. Check whether you have any pending updates such as game updates, software updates, or driver updates.
  • You can also check that your internet connection is working properly. It's also worth doing a speed test, to ensure there isn't a problem with your ISP.

What is Warzone Packet Loss?

Packet loss is, as the name suggests, when packets of data fail to reach their destination. They get lost somewhere along the way, between your computer and the game server. This missing data is what then leads to issues such as ping, stuttering, and getting thrown out of the game.

It obviously isn't an issue exclusive to Warzone. Packet loss can occur in almost any scenario where a server and a computer are communicating. However, gaming is one of the worst affected by it. As we mentioned earlier, there are lots of possible causes for packet loss. The main ones include:

  • Network congestion - a busy server struggling to deal with the amount of traffic
  • Software bugs - you may find packet loss happens more frequently after an update for COD
  • Hardware faults - so check your router, your firewalls, and your cables

The good news is that packet loss is very often a temporary problem that can either be fixed by the solutions we outlined above, or it just sorts itself out automatically. If, however, you are finding that it is a constant issue? Consider contacting your ISP for support, as well as Activision support for further advice.
