How do I restore the Airport status menu in Finder Toolbar and Network in System Preferences so I can turn Airport on and off with them? The only way I can turn Airport on or off is to unplug it or plug Time Capsule in. The Airport status menu Finder toolbar and Network in System Preferences look OK, the right controls are lighted, but they don't work. This has only been for a few days. I've tried to fix it by reinstalling OS 10.6.8 with no luck.
