It sounds like your WiFi is turned off but depending on the manufacture the switch to turn it on can be in a number of places. Most Laptops it is a FN+F1 through F12. You look for the Function key that has a picture of an antenna on it. Some laptops have physical switches just above the keybaord or on the side of the laptop.
You would be better off calling the Manufacture of the laptop to get help on this.
