I tried so many drivers and no one working.i open driver and he just close.Please give me driver conexant for Toshiba satelite p300-16e windows xp 64bit.Thanks in advice and sry for my english!
Looks like Toshiba has removed all the support pages/drivers for that device - so it's going to be trial & error and, unfortunately likely to be some questionable sources.
However, it looks like that laptop shipped with Vista, not XP?
Unless that laptop has more than 4GB of RAM (highly unusual for laptop of that vintage), you'll get nothing but problems with 64-bit WinXP. And I doubt Toshibna ever released any drivers for WinXP-64.
