Hello everybody!

I just finished installing Lion on my laptop Acer Aspire 5750 with 3GB Ram and Core i3. I'm trying to put Wi-Fi to work in Lion but I guess that I'm doing something wrong.

First, I downloaded a kext for my device and installed it with Kext Utility. Reboot and nothing happens, it stays without any Internet connection frown.png

My Wi-Fi chipset is Atheros AR9287.


If someone knows how to put it working, tell me please!


Thanks and sorry for my bad english.


I already edited the kext with my Device ID and Vendor ID...
