I assume your laptop does not have a hardware wireless switch button on the side. If I am wrong try to switch it on and off. <br />
If the wireless card needs to be replaces then watch this video: <a href="https://www.youtube.com/watch?v=QoItpvjDRjw" rel="ugc">https://www.youtube.com/watch?v=QoItpvjDRjw</a>

Even if switched off, it should still, I think, show up in Device Manager<br />
<br />
Post Note: &nbsp;I turned Wireless OFF on my laptop (Function to do this). It still shows up in Device Manager because the card is there and connected to the laptop board

Thank you all. I already solved the problem, I just wanted to figured out a possible reason why.<br />
<br />
John, I do not believe the card got unseated, since it was secured down with a screw.

Yes, the wlan card was secured to the system board &nbsp;via a socket, I just unsecured the screw, removed the metal guard, removed the card and re-inserted it.<br />
Maybe the motherboard or the card (WLAN) is on it's way out. I will have to request another card, if the problem happens again.
