How to increase blizzard downloader speed


If you are here, you are probably searching the internet because you are having slow speeds on your blizzard downloader.

There is good news though, you can possibly speed your blizzard downloader up by following some simple steps! That is what you are trying to do right? I recently ran into this problem while downloading the Diablo 3 client from the pre-sale and was getting right around 200kb/s. That was no good as it would have taken me about 12 hours to download the 7gb worth of files. So, this is what I did to my settings to speed things up a bit.

You can find below some simple steps and things to try to see what kind of results you get. Try these.

  • Check/Uncheck the "Don't throttle background download" box
  • Check/Uncheck the "Enable peer-to-peer transfer" box

If you see a speed increase after messing around with these, excellent! Both of those settings are checked for me.

Now the kicker for the article that most of you probably would have never thought to try.

  1. Open up internet explorer (not firefox) if you aren't already in it
  2. Go to tools (or settings) (might look like a cogwheel in the right-hand corner of the IE window)
  3. Go to "Internet Options"
  4. Click on the "Connections" tab
  5. Click on "Lan Settings" at the bottom
  6. Uncheck "Automatically detect settings"

My speeds went from about 200kb/s to around 2.8MB/s. That is a huge jump, and I'm sure you would agree. To get these kind of speeds, you need to make sure of what your internet speeds are to begin with. Go to to see what your speeds look like.

And that is all that I did to get my results. I downloaded the Diablo 3 client which was more than 7gb in under 30 minutes. That is the way Blizzard products should be downloaded.

I hope this helped your Blizzard downloader speed issue out. If you have any questions, thank you's, hate mail, or anything else, just leave it in the comments below.
