However, the WoW error 51900319 is a problem which appears in random times when playing the game and it causes big problems to the gamers because of the fact that it interrupts their gameplay which is pretty much important to the whole experience. Follow the methods we have prepared to try and solve the problem!
What Causes the WoW Disconnected Error 51900319?
The error is mostly caused by an in-game option called “Optimize Network for Speed” and you should disable this option as soon as you have the chance to. Also, the problem tends to appear to users using NETGEAR routers with old firmware or with the Dynamic QoS option disabled. Finally, the problem can sometimes be blamed on the IPv6 entry in your connections setting so make sure to try and disable it.
Solution 1: Disable the “Optimize Network for Speed” Option
This problematic option seems to have been the culprit for the error and disabling it managed to stop the occurrence of the problematic error code which disconnected users. The option is available from within the game options which can be accessed directly in the game or from the main menu.
Solution 2: NETGEAR Router Problems
If you are using the NETGEAR router on the computer you are using to play WOW, you might experience this issue quite often and it can be caused by two things regarding the router: old firmware or the disabled Dynamic QoS option. Both of these problems can be solved quite easily if you follow the steps below for both scenarios. The second thing you might want to do if you use a NETGEAR router is to enable an option called Dynamic QoS. Dynamic Quality of Service (QoS) helps improve your router’s Internet traffic management through better application and device identification, bandwidth allocation, and traffic prioritization techniques.
Solution 3: Disable IPv6 on Your Internet Connection
Disabling this option for the Internet connection you are using might solve the problem for you easily. The Internet Protocol version 6 is quite new and not a lot of older games support so it’s best for you to completely disable it as it won’t affect your experience.
