Ok! thanks for everybody helps....after days of trying. Realised that the cable is fault after borrowing one working one from another neighbour.
Now I have another problem....with W2k Profiles.
I am using wpc11 pcmcia card on my notebook. when with adminstrator log in, the card can access the AP.
But when log in as another standard user profile, the card is stated active but no link...why ??
