Wireless not working/missing drivers after installing new hard drive  

My hard drive went out, I purchased a new one, installed it and then I re-installed Windows 7 home premium 64bit on my Asus x53e laptop. Installation went good, but I don't have wireless connection. I went to device manager and there is yellow triangle on my network controller tab as well as PCI Simple Communications Controller and it says that I'm missing those drivers. I assume I need those drivers to connect to wireless. I've downloaded just about every driver on ASUS support site, and so far none have done the trick. I'm hoping someone can help me out.
I have the VEN and DEV code/number things for each,
network controller ven - 168C dev - 0032
and
pci simple communications controller ven - 8086 dev - 1C3A
if those help at all.

I just tried both of those, and both yellow triangle exclamation marks are still there
Any other suggestions?

I should have probably mentioned in my original post, that while I understand this stuff somewhat, I really have no clue what any of it actually is. If that makes any sense.
And no I haven't tried either of those.

Thank you both so much. I'm not 100% sure which one(s) it was that did the trick. But All the yellow triangles are gone. It's fixed.

Glad you got the problem fixed. Sometimes, Windows Update will have a generic wireless driver that will work until you can find the one from the manufacturer. Just a heads up.
