Diablo 4 is finally out, and just like the previous Diablo games, this game has also managed to garner millions of players right from the launch day. Just like the earlier Diablo titles, Diablo 4 is extremely engaging. In fact, Diablo 4 might be the best Diablo game yet.

But we cannot deny the fact that despite being a wonderful game, Diablo 4 has its fair share of problems. Players have been experiencing innumerable amount of bugs, glitches, server issues, errors, and performance issues since the release. This shouldn’t be a surprise, as most of you probably know how always-online titles are nowadays.

The issue we are talking about here is the extremely slow download speeds while downloading or updating Diablo 4. This is actually a huge issue because Diablo 4 is a fairly large game.

The game is already around a whopping 84 GB in size, and we all know how frequently Blizzard releases updates for their games (*cough* COD *cough). Imagine downloading all those updates with your download speed stuck at 1-2 MB/s.

How to fix the slow download speed

If you do a bit of research, you will find a ton of websites posting all kinds of “fixes”. But until you have awful connection issues that actually need fixing, none of them will work. You will be only wasting your time with those fixes. Let’s see how to fix this issue. But first, just visit Speedtest once and do a quick speed test to make sure that there is no issue from your side and that you are getting full download speed.

Sorry to say, but there is no “free fix” for this issue. And I am telling you this because I was struggling with the exact same issue. I have a 400 MB/s Fiber connection where I get a download speed of 40-50 MBPS almost everywhere.

But on the Battle.net app, I was getting a download speed of only 1-1.5 MBPS while downloading Diablo 4. Now, this could be very much because of the overloaded server. But, I was sure that it wasn’t the case. And it is very frustrating as you have to sit for hours before you can even start the game.

That is when I decided to try out a VPN. I already had a year-long subscription to a VPN called Private Internet Access. So all I did was:

  1. Installed Private Internet Access
  2. Set VPN Server to US New York City
  3. Restarted the Battle.net application
  4. Restarted the download

My download speed went from 1-1.5 MBPS to 25-26 MBPS. Check it out:

Yes, I know that it is not 50 MBPS, but it is way better than waiting countless hours for a single update to download.

The slow download speed is not an issue from the side of your connection. It is a server-related issue that can only be fixed by Blizzard. I have tried downloading other games from Battle.net as well, and every time I got my full download speed.

You can use any good VPN for this, actually. You just have to make sure that the VPN you are choosing doesn’t have data limits.

There is another theory that I have seen people on Reddit talk about a lot. According to some of them, the slow download speeds are due to the game being installed on a slower storage device. A lot of COD users have claimed that they have fixed this extremely low download speed issue by just installing the game on the exact SSD where they have Windows installed. Though, I haven’t tried this, hence cannot confirm.
