Forgive me if I've posted this in the wrong place.

Found this fix while troubleshooting a laptop with a broken external wireless internet on/off switch; I thought I'd share it with the world. The problem is as follows: external switch breaks, so computer thinks wireless internet is to be disabled. This is a problem for anyone who wishes to use wireless internet on a laptop. Here's the solder-free solution provied by Freddyspam from notebookforums.com, albeit a bit ghetto:

"
For miniPCI cards: Pin # 13 controls the "silent RF" mode. That is what most hardware switch activate in order to turn off your wireless. You'll notice that while you lose your internet connection when the switch is turned off, your hardware is still visible in device manager. The solution is to take your wireless card out, and apply a small amount of tape over just pin #13, and put it back in. That's it. Your wireless card will always see the hardware switch as being turned on. You can still disable the wireless using Fn+f2 or whatever the hotkey is for your laptop.

The pin numbering alternates from side to side so that all odd pins are on one side and even pins are on the other. So if this is your MiniPCI card, tape this pin:

The gap between 1 and 3 represents the notch in the card. I hope this helps someone else as this took me hours to figure out.

Mini PCI express: it is pin #20, which is responsible for the same function (also active low). It is located on the underside of the board, second pin from the notch toward the side with more pins.

I did try this with a miniPCI express card and to pleasent surprise, it worked perfectly.

Hope this helps someone!
