Alienware M18x R1 Wireless (driver?)

I cannot get the wireless to work on my laptop. I have tried every driver on the download section for my computer and nothing has worked for wireless. the only driver that works is the "Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20)" and the wireless isn't working with that which makes me think it isn't a wireless driver. If it is can anyone tell me what I'm doing wrong >.< been working on this for a while but I cant get it to work,


Also, I am an IT technician(mostly computers) by trade with A+ and Security+ so I do know troubleshooting but I also know that its usually something simple when you cant figure something out. I appreciate any help. Thanks!
