The Transmission Error in Call of Duty has been effecting players of both Modern Warfare and Warzone. While bugs are an inevitable part of any online multiplayer game, especially one as popular as COD, they are still frustrating when they present you from playing your game of choice. Today we'll be taking a look at what the Transmission Error actually is, and what you might be able to do about it.

How To Fix 'Disconnected Due To Transmission Error' in Modern Warfare and Warzone

There are a few steps you can take to fix a transmission error on COD:

  • In the very first instance, check the server status for the game. If there is a server issue, there isn't a whole bunch you can do about it, other than sit back and wait. Maybe make a sandwich or watch a film.
  • If there is a server issue, you might consider trying a VPN, in case the issue is a local server problem. A VPN can connect you with a different server, that may not be experiencing issues. On the flip side, if you are using a VPN, turning it off, and connecting to your local server, may have a similar effect.
  • Assuming all is well with the servers, the next step is the tried-and-trusted, turn everything off and back on again. Restart your device and relaunch the game.
  • Next, is to see whether any of your game files have become corrupted. If you're using the Blizzard launcher, then do the following:
    • Open the Battle.net desktop app
    • Choose your game, click the Options menu, and select Scan and Repair
    • Click Begin Scan
  • If you're using Steam, you can do the same thing by following these steps:
    • Open the Steam client
    • Select your game from the library and click on Properties
    • Choose the local files tab, and then click on the Verify Integrity of Game Files tab

If these steps haven't worked, it's time to break out the big guns. Next, its time to take a long, hard look at your router settings.

  • The first thing to do is change the NAT type on your router. It usually comes in three flavours, and changing it to open will give you the best chance of fixing those communication problems.
  • It's also worth ensuring that UPnP (Universal Plug and Play) is enabled on your router. You can do this via your router's online account page.
  • Once you've updated your router settings, you can check to see if you have an antivirus that may be blocking the game, and disable it, or make sure your game is on the 'approved' list of apps.
  • If none of the above has worked, it's time to consider uninstalling and then reinstalling the game, as a last, desperate act.

What is the Call of Duty Transmission Error?

When players are hit by the transmission error, they receive the following message:

Disconnected due to transmission error

This, perhaps self-evidently, renders the player unable to access COD to play online. Typically, the cause of this is because of an unstable connection between the end user's device, and the game server. This can be caused by a number of different factors, most frequently:

  • An unsuitable NAT type
  • A problem with the router
  • Issues with the game server
  • Corrupt data
