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.

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

Go to the pathping article page on the Battle.net website

Select Diablo III from the combo menu

Write down the IP address you want to run the test on

Launch an elevated CMD instance

Type pathping x.x.x.x (replace x.x.x.x with the IP you wrote before)

Wait for the test to come to an end

Check if there’s any packet loss and where is it located

2. Use Blizzard’s Looking-Glass tool

Head over to the Blizzard Looking Glass website

Select your region from the menu

Choose Diablo 3 from the service menu

Make sure at least MTR is selected

Hit the Run Test button

Wait for the test to complete

Check if there’s any packet loss in the Test Result screen

How to fix sudden packet loss in Diablo 3?

1. Try using a VPN

Download Private Internet Access PIA Diablo 3

Install it on your PC

Launch it and log into your account

Connect to a low ping server

Run any of the tests above

Check if the problem still persists

Private Internet Access is a great all-round VPN service from Kape Technologies that can help you tackle packet loss in Diablo 3. However, note that it might not work if the problem is not on your ISP’s side.

Experiencing sudden packet loss in Diablo 3? PIA could come in handy.

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 Battle.net launcher window, click the Diablo 3 Options button and select 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.

Diablo 3 packet loss can be solved

To wrap it up, you’ve learned how to check for packet loss in Diablo 3 and discovered a bunch of quick fixes for this issue. If the issue lies on your ISP’s side, the most effective fix would be investing in a trustworthy VPN.

However, there are many potential causes for packet loss, and your ISP might not be responsible for all of them. Thus, you might need to rely on your troubleshooting skills to improve, if not fix packet loss altogether.
