What is the reason of not working of wifi in hp laptop after the driver is insta

a lot of HP users are experiencing this problem after an HP update. I use an HP 1000 notebook. Here is what worked for me
Restart you computer and press f8 during startup. From the menu that appears select "Disable Driver Signature Reinforcement". When the windows is started you should have your WiFi back.
This is a temporary fix, you'll have to do this every time you start your computer.
