Constantly Disconnecting to Error 51900319. Can't seem to find any helpful advice!

I’ve been playing WoW with no issue for the last few months, but ever since I upgraded my PC a week ago, I’ve had numerous disconnections in Classic. I’m sure that all my drivers are up-to-date, I’ve reset and flushed my DNS, I tried removing out of date add-ons, nothing is working to solve this issue.

The biggest mystery us that this is an inconsistent issue. Sometimes I get back to back disconnections, I can’t stay online for more than a minute. Other times, I can play for hours with no problem. It’s giving me a lot of stress and making group play really hard.

I’ve seen people with similar issues reporting this, with no solutions that have worked for me thus far. Is there anything I can do to solve this, or do I just need to give up on WoW?

I don’t think previous posts would be related to your issue because you said:

Probably something on the new PC, either bloatware that came installed with it or the network interface card (NIC). Only way to check is to look through your Windows Event Viewer logs under system logs and see what’s reporting a disconnect.

Thanks for the reply! Here are my logs from just this morning, where I experienced at few disconnects during normal questing:

Hey friend - I was having a similar issue after updating my internet provider. I did everything you did. I had my internet provider out here three times telling me it was a WoW issue and that there was nothing on their end.

As a last request, we had them upgrade all of our cabling to Cat6 (from Cat5) and I haven’t had an issue since. It is worth a shot.

Thanks for the reply! Were you having issues with other parts of your internet as well? Or was it just WoW? I’m just trying to see how similar our situations might be.

Try switching to a different DNS in Windows and also make sure Ethernet and WiFi aren’t enabled at the same time (Windows is very bad at managing the two).

I was only having an issue with WoW nothing else. All other video games devices played fine on the new internet. I have three kids - we run VR, playstations, and our computers all at the same time. Only WoW was disconnecting.

We hardwired my husband’s computer - still dropped
I ran wifi at the same time - still dropped.

We found one cable that was a few feet long that actually would impact both the hardwire and wifi computers. Had him change that and we haven’t had an issue since.
We made our internet provider change out all Cat5 cables in the house, which he happily did since he just ran it along side the old cable then pulled the Cat5.

No issues with any other internet. I love our new fiber line. Fast and now this is fixed, I am beyond happy.
