Hello guys , How are you ?
Will go into the issue directly
when I updated my minecraft to 1.3.2 and 1.4.2 , then when I press multiplayer in minecraft ,
the servers come so slowly like ( hunger game servers ) , and become high ping for all servers
it's just in update 1.3 and 1.4.2 ! in other meaning , when i back to 1.2.5 it's ok , no lag in multiplayer the servers come very fast in 200-300 ping  !
I expect that this problem from my wireless router , but my internet is so good ..
or maybe from the new feature -( lan ) !? 
 I took my laptop to my cousin's house , and i test the multiplayer and there are no lag ,and knowing that my cousin has weak internet connection compared with my connection ..
So please guys , if anyone have an idea of that problem please help me !
