Looking for ways to fix packet loss in Modern Warfare 2? We've got some tips for you.

So you have got your hands on Modern Warfare 2 but the packet loss issue is really bothering you, huh? Packet loss can cause lag in Modern Warfare 2 as well as high ping, which is extremely undesirable in gaming.

The good news is that it's actually not that hard to fix. Here we have compiled a list of things that might be able to help you out.

How To Fix Packet Loss In Modern Warfare 2

As the name suggests, packet loss or data loss is when packets of data fail to reach their destination. Network congestion is the most common cause of packet loss, but it can also be caused by a number of other problems, such as software bugs or hardware faults.

Here are our solutions to fix packet loss in Modern Warfare 2. Before trying out the following tips, makes sure your OS, game and drivers are fully updated.

Some easy troubleshooting tips

Let's start with easy fixes before we get into more complicated stuff.

  • Restart your modem or router.
  • Enable QoS – Some routers come with a Quality of Service (QoS) feature, which when enabled, allows you to set traffic priorities to the devices on your network, as well as traffic types.
  • Try a VPN to connect to a server in a different region, which might be experiencing less traffic. Have a look at the best VPN services.
  • Try to minimise the amount of traffic on your network. Close any background apps that might be using data. Also, disconnect other devices from your router, if possible.

Still no luck? No worries! We have other suggestions to tighten up your connection to help reduce the potential for data loss. Keep reading!

Play on a wired connection

While convenient, Wi-Fi connections are often unstable which can dramatically affect the quality of online gameplay. Even the strongest wifi signals experience packet loss - which causes lag, disconnects, freezing, matchmaking errors, etc.

On the other hand, wired Ethernet connections offer better speed, lower latency, and more stability, which is vital for online gaming. Activision too recommends using a wired connection.

Change your NAT type

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:

  1. Type in your routers IP address into your browser
  2. Log in to your router
  3. Find your router’s Port Forwarding section
  4. Put the IP address of your PC or console in the correct box in your router
  5. Enter the correct TCP and UDP ports for your game in the corresponding boxes. These are as follows:


  • TCP: 3074,27014-27050
  • UDP: 3074,3478,4379-4380,27000-27031,27036

On PlayStation 4

  • TCP: 1935,3478-3480
  • UDP: 3074,3478-3479

On PlayStation 5

  • TCP: 1935,3478-3480
  • UDP: 3074,3478-3479

On Xbox One

  • TCP: 3074
  • UDP: 88,500,3074-3075,3544,4500

Xbox Series X|S

  • TCP: 3074
  • UDP: 88,500,3074-3075,3544,4500

Hopefully, one of the tips will definitely work for you. If it doesn't and you are finding that it is a constant issue, consider contacting your ISP for support, as well as Activision support for further advice.
