I have posted about this problem in past years with no explanation and seemingly no one who has responded knowing what i am talking about , at least in regards to blizz response.
At times in a BG when i go to enter a vehicle i will get DC and once back in game will get DC after 4 seconds and then going into DC loop over an over on that toon until the BG is ended. Also happens in Gravity lapse brawl when i land on ground some times. This has been an occasional thing over the years no matter what expac , across different PCs , with and with out add ons , modems , routers and with and with out VPNS
And the only solution for the old Wow Error 51900319 message is just reset every thing ect. But my problem is not getting DC loop from the game its just random BGs once in a while and has been on increase as of late
I know other ppl in my pvp communities who also have this happen sometimes also and i was hopping to find a solution rather than having just to suffer this
