Q: wi-fi: no hardware installed
I've installed Mac OS X Lion on my MacBook (white, late 2007) and lost my wi-fi connection. It worked fine with Mac OS X 10.6.8 but after upgrading to the Lion I get "Wi-Fi: No hardware installed" sign in the upper right corner of the screen. I reset PRAM but no avail.
Any suggestions?
MacBook, Mac OS X (10.7)
