Found the problem (with the help of linux wireless mailing list). I am very sorry for disturb. The problem is that: Ubuntu have startup script network-manager i disabled graphical network manager, but i didn't know that ubuntu has a startup network-manager script (and wpa supplicant script). I have killed process related to network-manager and wireless work correctly.
