Maple doesn't work on my wireless. ;-;

I don't know why. On both vista and W7, it won't work. In vista, it'll get to the choose character screen then it'll force me to the login window and keep me with the "this character is logged in" message for a minute or so. On W7 it won't even show me the play button screen. On wired connection it'll work fine, and everything else works fine. (i'm on wireless as i type this)

Help. ;-;
