Hello, i have a compaq presario 103LA, i buy it used. The problem is that the atheros AR5BXB63 is not detected by the system, even from its start, the button of wifi remains red and then, into xp the system is not capable of detect it, so i can't install the drivers or whatever i want to do with the wireless network. I dissasemble the card but nothing seems be bad, i don't know what to do in this case. ¿Can you help me? I tried to see if i can fix it from the bios, but it seems to don't show the advanced settings, so there i can't do nothing. (The bios is phoenix F.3E) Thank for your answers, good bye.
