WOW Error Code 51900319

Very simply put, WOW’s genre is ‘multiplayer’. To run MMORPG and in connecting to any player anywhere in the world, you require the internet. Therefore, you need access to the internet. If there are internet issues present when attempting to play WOW then correspondingly, you’ll likely see the WOW Error Code 51900319 you are facing right now.

According to Blizzard entertainment support,

WOW Error Code 51900319 means you have likely lost your internet connection and have disconnected from the server as a result.

However, multiple players have encountered this error while having a perfectly stable internet connection as well.

Why Do I Keep Getting Disconnected From The Server In WOW?

From what we have gathered, the error can result from both the server and player sides. In a tug of war type action, players blame Blizzard Entertainment when they lose connection citing that they have a stable internet and conversely,  stating a problem with WOW’s game engine or server. Likewise, Blizzard Entertainment keeps saying that the error is most likely user-caused and has nothing to do with their game or servers.

We have researched that the connection can be a result of various reasons, that all translate to “You have been disconnected”. WOW has a tightened latency network which means it disconnects immediately at the first moment of data or network loss. This can either result from bad internet, or  can also be caused by weak graphic cards or CPUs which can’t take a load of heavy internet and extensive graphics or WOW at the same time. 

How Do I Fix WOW Error Code 51900319?

  1. Click on Esc to open the Main menu
  2. Click on System
  3. Then click Advanced
  4. Go to the background FPS in your video settings.

  1. Go to the Settings section
