You bought a windows laptop with a built in wifi which actually works with a turn on and off button or you may call it a wifi switch. After some days, the wifi stopped working because the button was unable to turn it on. Typically most of the new laptops have now a wifi switch to turn on and off the wireless hardware which if fails gets a status of wifi not working for the user.
When the wireless components of a laptop are turned off the wifi switch shows a red light else it shows a white light in working condition. When the switch fails to turn the wifi on there is a red light which never turns to white one.
The same problem can happen when you upgrade your wireless card driver or else upgrade your windows XP to windows 7 or else windows 7 to windows 8. In windows 8 it is a common problem while trying to turn on wifi with button but simple wifi not working.
