HP Laptop 2125nr, XP SP3, completely updated... Everything involving the integrated wireless adapter & its drivers have vanished. The hardware profile (Device Mgr) is displaying as if it never existed. Installing fresh copies of the adapter & drivers from the HP website didn't work, the lap is thinking that there's nothing to install. Rolling back service pack 3 didn't work as well. I've also did an online scan of the hardware, found & unidentified - no luck. Any ideas? Please?
