  • Quit out of the game completely.
  • Reset your internet router.
  • After waiting sufficient time for it to fully reboot, launch the game.
  • That should fix the issue, but if not, close the game once more.
  • Connect your console or PC to another Wi-Fi network (where possible).
  • Connect your console or PC to a mobile data hotspot.
    • Note: Be mindful of any charges this may incur.
  • Launch the game under your new connection.

After performing the above steps, you should have provided a stable connection for the download to be completed. Feel free to revert back to your initial network settings once it’s done, then get back to playing CoD: MW and/or Warzone as normal.
