Windows 7: Impossible to connect wifi with my ASUS laptop

Hi,
1st, sorry for my English, I'm french and I'm not really good in IT.
I have an ASUS with an Athéros Wireless R9285.
Since the last update, I can't connect in wifi anymore (but it's ok with the cable, and ok with my other computer).
I first though it was the on/off wifi button, or the Fn/F2 command, but no.
Then, I tried to connect/unconnect the card, change the power specification, try all the anti viruses I've got and make a "restauration" at a date before the update and so the issue... Nothing...
I've read all the forum I can found on the subject, try many solutions, but still nothing.
I was close to be desperate when somebody told me it could be a problem with the Microsoft virtual wifi miniport, and give me your site adress.
Could somebody help me please ?
Thank you by advance

Hi and welcome to the forums.

First things first, could you please fill in your system specs for me so I can give better assistance. Thanks.

Now in the meantime I have two ideas. One, do you have a system restore point to go back to. It should make one whenever you install an update. That might solve your issue. If that doesn't work, go to the ASUS website and go to drivers. Download the latest drivers for your laptop.

Hope this helps
