Fix 1: Reset your network devices

When faced with the Diver error, the first thing you should check whether it’s a local network issue. It is possible that your router or modem has been overloaded with data, grinding your internet to such a halt that the download has failed. In this case, restarting your network devices may fix it.

Here’s how you can restart your modem & router:

  1. Unplug your modem (and your router, if it’s a separate device) from the power socket.

  2. Wait 60 seconds for your modem (and your router) to cool off.
  3. Plug the network devices back in again and wait until the indicator lights are back to the normal state.
  4. Restart your computer.
  5. Connect your PS4/Xbox One/PC to the internet.
  6. Launch Warzone, then check to see if the download has been successful and the error is resolved. If yes, then great! If the error persists, please try Fix 2, below.

Fix 2: Update your network driver

The network adapter driver, which works as an interpreter between your network adapter and your PC, is essential to the proper functioning of the network adapter.

  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 Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version– you’ll be prompted to upgrade when you click Update All).

Fix 4: Use a VPN

Some players have managed to download the update with the use a VPN, so you could give it a shot to see if this does the trick for you. It can be tempting to use a free VPN service, we do not recommend it since a free VPN may not provide secure, fast or private enough connections.

Below is a list of VPNs that works with CoD:

According to CoD’s Terms & Conditions, you may only face being banned if you use a VPN to gain “unfair” advantage during gameplay or to manipulate stats and game data. This means that so long as you don’t cheat in the game, you will likely be fine. If you want to be on the safe side, you can use a VPN with strong encryption and leak protection.

Fix 5: Contact Activision Support

If you’ve tried every possible fix but the error still lingers on, it is time to check Activision Support for the online status of the platform you’re on and see if it’s experiencing down time or connectivity issues. If this indeed goes on, there’s not much you can do but wait for the servers to be recovered.
