I can confirm this is happening to me too - I have gotten into the habit now of logging my team in and just waiting for a few minutes at the character select screen before "Entering World". Invariably anything between 1 and 3 accounts will just disconnect with the 51900319 error. It's not the end of the world of course........just annoying. Once I log them back in, everything is pretty much good as gold.
This has been only going on the past few weeks.
Things I have tried (this is a wired connection as well btw):
- Dropping InnerSpace load aggression down to moderate
- Logging them in one at a time
- Disabling Optimize Network Speed in WoW Client
- Flushing DNS cache
- Restart router
None of that worked.
I am currently running development updates of InnerSpace after Lax was kind enough to add some support for my Razer Tartarus V2. So as an experiment, I rolled back to the live version which is 6423 and logged in a few times. No disconnects.
Then I re-patched to the lastest dev build of 6461 (I NEEEEED my Tartarus
) - and so far, no disconnects - I will do a more thorough test tomorrow as I just logged my teams on for a few minutes to check if they disconnected and they didn't.
If you are getting disconnects, perhaps try a roll-back to live if you are running the dev patches, then re-patch. Perhaps something broke somewhere in the update process between the various dev builds as there have been quite a few in the last month or so.
