 4. Connecting with an Ethernet Cable (Optional)

Blizzard’s stricter network latency restrictions are one cause of the WOW51900319 problem. As a result, WoW Servers automatically disconnect when their network fails to react. As a result, we are able to use high-speed Ethernet. A high-speed Internet connection is ideal for gaming.

Wifi isn’t as reliable as Ethernet because it fluctuates even if it’s the best quality. Optic cables transport data over Ethernet connections. In this case, the ISP is correct, therefore there is less fluctuation.

It may be concluded from the foregoing that Ethernet connections provide excellent throughput while also exhibiting low network latency. There will be fewer disconnects as a result of this. There will also be no more Non-Responsive behaviour. Error WOW51900319 will be fixed.

The server slowness can be a problem for only one user at a time. This is the result of a software bug or other technological issue. Ping times can be drastically reduced.

5. VPN

In some cases, one region’s server is extremely busy. A large number of pings raises the server’s load, and an error message such as WOW51900319 appears. Pings can no longer be processed by the server.
