Windows Seven Connection Problem

Hello folks ! I've got a big problem ! I formatted my acer 8920g to install windows seven. Everything went fine from installing the os to the drivers. But now I can't connect to my wireless network ... It says I've got a limited access to my network and the troubleshoot didn't help , they say I've got the wrong password which is not the case. I also have a program wit my router that create an install file on a usb key and when I try it on my laptop, it says my radio is off. That made me notice that my key that I habitually use to toggle on and off my wireless card is not working. I know what is the problem, but I don't know how to turn it on from somewhere else in the computer My bluetooth button right under the wireless button is working so it made me suspicious about the problem.

Except from that, only my Cineash Media Console volume controls are not working ( but the play/next/back/pause/mute buttons are ) but I don't really care about that since I havn't used it really much .


Now the main reason to buy a laptop is no more working

Thanks a lot to whoever find the answer to my question with their precious time

Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller and
Intel(R) Wireless WiFi Link 4965AGN

I've got 1 thing in other devices, and I don't know what is it to update the drivers, even windows can't find anything to solve it...

Everything is working on my laptop except for the wireless ...
