Problem with N5010 WLAN Driver

Hello guys, I'm new to this forum, but anyways:

I have a problem with my Inspiron N5010, I just reinstalled Win7 Ultimate x64 and I can't get the drivers to work. I have downloaded R252544 and many more drivers, but an error keeps coming up, saying that it is not compatible with my system or cannot be installed. I am currently using Ethernet cable but I need to use WiFi. Any help would be greatly appreciated.
