i have same problem , but only in prime time

the day when people working in europe , i dont have any problem, micro lag ( connection) for 1 sec max

but then when its prime time, everyone freeze around me for sometimes 40 sec ...

and it end up with error 90000, i get kicked , and cannot come back in game

im using WIFI also, my friend can log out of the game and come back with no problem minus the queue ( but numbered queue)

so i think when there are too many people on server , the worse connection start exploding, and SE put you on a list, or if its not a list, there is the following process :

if connection worse than "x parameter" => world full 1017 and you wont be able to log again before world get emptier

conclusion ( my opinion)

game keep only best connec at prime time
