Turn wifi on dell - Dell Studio XPS 1640 Notebook

There should be a switch on the side or at the front of the laptop. If the switch is on, then you can also toggle the Wifi on and off by a set of key strokes. Normally you can hit either the ALT, CTRL or FN key + the F1 thru F12 key that toggles the wireless. Most times its the FN key, but I have seen the Alt key used. Press and Hold the FN key then hit the correct F1 thru F12 key that toggles the wireless. The correct F1 thru F12 key will have the wireless icon )))) on it. Normally if you hit the correct keys to toggle the wireless the screen will display Wireless On or Wireless Off.
