What causes packet loss in Black Ops 4?

Let’s get one thing straight: packet loss occurs whenever data packets transmitted throughout the connection never reach their destination.

That goes both ways, so you may not receive packets from the server, or the server might not receive packets from you.

Unfortunately, there are several reasons for why packet loss occurs. Here are some of the most frequent ones:

  • Network congestion (most common reason)
  • Improper connection maintenance
  • Poor ISP traffic management
  • ISP bandwidth throttling
  • Insufficient bandwidth (cheap Internet plan)
  • Using Wi-Fi instead of a wired connection
  • Server-side problems
  • Subpar hardware components (including old routers)
  • Outdated drivers on the system
  • Router running an older firmware version

As you can see, there are more than just a few reasons why you may experience packet loss in Black Ops 4.

Since there are several potential causes for packet loss, it’s also more difficult to troubleshoot fix this issue.

How can I fix packet loss in Black Ops 4?


  1. Buy a VPN subscription plan (we recommend Private Internet Access)
  2. Download the VPN installer on your PC
  3. Install the VPN client and launch it
  4. Log in to your VPN account
  5. Connect to a fast server (nearby servers are usually the fastest)
  6. Launch Black Ops 4 once more
  7. Check if you still experience packet loss

Chances are that simply routing your connection through a VPN tunnel will take care of things.

However, you must keep in mind that a VPN won’t do wonders if the issue is caused by bad hardware, outdated drivers, or server-side issues.

In fact, using a VPN will only fix your Black Ops 4 packet loss if your ISP throttles your connection or there’s some heavy network congestion.

Long story short, the packet loss must occur somewhere in the middle, and not on either endpoints, for the VPN to work.

We recommend Private Internet Access since it features a huge network of over 22,000 high-speed servers (and counting).

Therefore, there are plenty of servers you can switch to in case the one you’re currently on doesn’t work or is extremely slow.

Flush your DNS

  1. Launch a CMD instance with Administrator rights
  2. Run the following commands, one by one:
    • ipconfig /flushdns
    • ipconfig /registerdns
    • ipconfig /release
    • ipconfig /renew
    • netsh winsock reset
  3. Restart your PC

It’s common that cached data build-ups can affect a system’s connectivity and cause issues such as packet loss.

The same thing could happen with Black Ops 4, since it requires a stable Internet connection in order to run as intended.

Therefore, you could try flushing your DNS using the steps described above.

This process should clear any faulty DNS records on your system and maybe even solve your Black Ops 4 packet loss issue.

Troubleshoot the issue manually

  • Reboot your computer
  • Restart your modem and/or router
  • Check your cables for damage and replace them if necessary
  • Upgrade your cables to a higher category (i.e. CAT 5 to CAT 6)
  • Restart the game
  • Use a VPN to change regions
  • Close any background bandwidth-hungry apps and services
  • Update your router’s firmware to the latest version
  • Make sure your system drivers are up-to-date
  • Call your ISP and ask them if they can look into the matter (if you notice it keeps occurring)
  • Contact Activision’s support team and ask if there’s any technical issue with the servers
  • Avoid peak hours if you suspect network congestion (or use a VPN)
  • Check that your firewall/antivirus isn’t restricting Black Ops 4 in any way
  • Always use a wired connection instead of Wi-Fi, if possible (Wi-Fi packet loss occurs more frequently)
  • Change your wireless router’s broadcast channel
  • Upgrade your Internet plan if it’s a cheap one with limited bandwidth
