One of the best role-playing games for a long time now is definitely the World of Warcraft. While playing it, the worst thing that can happen apart from distraction is experiencing some problems such as the WOW51900319 Error.

The frustrating thing with this error just as you will find out with any other error that occurs when you are gaming is that it can almost destroy your gaming experience. There was a time that it became a very serious problem among gamers which has led Blizzard and other gamers to start looking for solutions.

Meaning of the WOW51900319 error and causes

Generally, each time you come across any error code as this, there is usually something that it could signify. As revealed by Blizzard, what this error simply means is that “you have been disconnected from the server.” Essentially, you have lost connection with the servers of World of Warcraft.

Instead of seeing that particular error code, one may get to see things such as Disconnected with error BLZ51900075 or even Disconnected from World of Warcraft. These, according to Blizzard, also mean the same thing as the first error.

While Blizzard is insisting that the problem is from the gamer’s end, gamers insist it is from the other end. Nonetheless, there are some things that have been linked to the error including playing the game on high FPS and failure of the network to respond. Others have claimed that they experience the problem when they switch programs to do something using the ALT and Tab keys.

The good news, however, is that no matter the cause, there are many available fixes for the WOW51900319 error.

First Method: Change Your FPS

More than almost all other things, what has been said to cause this problem is taking your FPS too high. This is because it will make it hard for the internet connection you have to move with the servers of Blizzard because of the network latency, hence you will get the error.

The simple fix to this error is to have your FPS set at 30. Here are the steps to fixing that:

  • Either directly click the Game Menu icon of the game or press ESC. Both will take you to the Game Menu.
  • Select System in the Game Menu
  • On the left side of the System, select Advanced.
  • Check the box for Max Background FPS
  • Set your FPS at 30 and then click Okay

Note: Also following the same steps above, you can decrease the Foreground FPS which has also been found to solve the problem. Once you get to the Advanced option, you will see the Foreground FPS. Decrease it a little and save.

Second Method: Check your Network

Since as earlier pointed out, the network latency requirements of Blizzard has been tightened, your network has to be very good. If you are using a modem, there is the possibility of fluctuation in the network which can easily open you up for the error.

The solution to this will be to get an ethernet cable because it offers a more stable connection once you have a good ISP. The advantage of using ethernet cable is that while the network latency is less, the speed is higher than what you get with a wireless connection.

Third Method: Log out from
