I have an HP dv6, icore 7 second generation, Windows 7 64 bit, I was using the internet the other day and my wireless stopped working. I was given error 651. It seems as though my laptop is not recognizing my wireless adapter (realtek PCIe GPE family adapter). I also noticed that in device manager there is now an unrecognized device. Is there anyone here that can tell me how to fix this problem?
