I recently upgraded from Windows 7 Pro to Windows 10 Pro. Sony Vaio VGN-FZ290 laptop. The machine went through the Microsoft testing OK prior to the update. After update I am getting periodic blue screens with error "IRQL_NOT_LESS_THAN_OR_EQ..."
Also, now am unable to access network drives from this computer. I receive error message for this that "one or more network protocols is missing from this computer."
I have tried all suggested fixes for these problems already on the forum. I believe the problem is the driver for the Intel WiFi card 4965agn. There is no Windows 8.1 or Windows 10 driver for this card that I can find.
Anyone have any other suggestions? Thank you!
