still disconnect every few minutes(solved)

Very glad to have a great server to play wow . I played the game at about 1:00 am on 3.1.
At first ,as a chinese player,we all used the chinese client,the folder data/speech2.mpq(a chinese speaking) caused disconnect every few minutes. so,i installed the english client, then the game worked well. And if you delete the data/speech2, the chinese client worked well too.
but when the server restarted at about 5:00 am(i don't remember the exact time),i started disconnect from the server again,even the english client disconnect too. The client is clear,i re-installed it for times.
Then at about 14:00,after the server restarted,the game worked well again,but after i used the addons,disconnect again.
now i re-installed the client for several times,and don't use any addons,but there's nothing for help.
PS:i tried to use the english and chinese client ,but they all disconnect every few minutes. some times,the chinese will disconnect immediately,the english client disconnect one or two minutes. when you move, you'll disconnect very soon,but if you don't move,it will be longer.
last night ,i have re-installed my PC os even,but it don't work well,still disconnect every few minutes.
in the same network,my notebook worked well,so it sames not my network caused the prob.
And,at last,there is about half wow-players in asia,it lags very bad for asia players,will you pretty boys have a plan to set a server in asia, as i know it's the greatest vanilla server in the world now.
God will forgive my poor english!
