Packet loss Diablo 3

Diablo 3 is a popular hack’n’slash game developed and released by Blizzard Entertainment. It’s the third title in the Diablo series and was released way back in 2012. That’s 8 years ago and the game is pretty much still alive.

But that shouldn’t exactly come as a surprise, considering that even Diablo 2 still has a lot of active players.

In Diablo 3, players create a character by choosing one of the 7 classes available in the game and embark on a journey to defeat Diablo, the demonic overlord. You can do that solo, or join others.Main screen Diablo 3

If you’re familiar with previous releases, you’ll know that teaming up doesn’t mean it’s going to be easier. In fact, the difficulty of the game increases as more and more players join your server.

However, we didn’t gather to discuss Diablo 3’s awesomeness. Instead, we’re going to analyze one of its less-fun parts: sudden packet loss.

What is sudden packet loss in Diablo 3?

Packet loss is usually the same, no matter where you encounter it. Packets of data that are transmitted through your connection never make it to their destination. As a result, you can experience more noticeable issues.

For instance, the game slows down to a pulp, you rubberband all around the map, you can’t really use your inventory, and the game simply stops responding to your commands.

If the packet loss is severe (what we like to call a packet loss storm), you might even disconnect from the game. And that’s not exactly something you’d want happening while you’re battling Diablo or any of its spawns, believe me.

How to see packet loss in Diablo?

1. Use pathping

  1. Go to the pathping article page on the website
  2. Select Diablo III from the combo menuIP address Diablo 3
  3. Write down the IP address you want to run the test on
  4. Launch an elevated CMD instance
  5. Type pathping x.x.x.x (replace x.x.x.x with the IP you wrote before)CMD pathping
  6. Wait for the test to come to an end
  7. Check if there’s any packet loss and where is it located

2. Use Blizzard’s Looking-Glass tool

  1. Head over to the Blizzard Looking Glass website
  2. Select your region from the menu
  3. Choose Diablo 3 from the service menuLooking glass Diablo 3
  4. Make sure at least MTR is selected
  5. Hit the Run Test button
  6. Wait for the test to complete
  7. Check if there’s any packet loss in the Test Result screen

On the bright side, a VPN can help you solve many other issues such as privacy concerns, securing your connection, and circumventing geo-restrictions.

2. Perform manual troubleshooting

  • Restart your router and/or modem
  • Try connecting straight to your modem or home line
  • Use a wired connection instead of wireless (Wi-Fi leaks packets often)
  • Check and replace/repair/update/upgrade any faulty component on your end (drivers, cables, PC, router)
  • Avoid peak hours if possible
  • In the launcher window, click the Diablo 3 Options button and select Scan and RepairDiablo 3 scan and repair
  • Restart the game
  • Call your ISP if it seems the problem is on their side
  • Contact Blizzard and inform them if the server seems to be having problems

Keep in mind that the most frequent cause of packet loss is network congestion. There’s pretty much nothing you can do about it, except if you’re a network administrator and know how to optimize routing and manage subnets.

Thus, the best way to improve packet loss is more often than not waiting for it to fix itself.
