chili555 thank u so much for your help and support, u r really so kind.

i really get off with this problem, so i removed the ubuntu and installed kubuntu 12.10
and this time 64 bit, and w-less worked just since 15 min perfect.

and I'm still test it but i didn't test the LAN cable yet.
and sure if something wrong happened 'll back to u again.
