Hello,

My current-generation MacBook Pro 15" (10.6.5) intermittently has problems turning the wifi (airport) on. The usual symptom happens when I:

Sleep the machine
Open from sleep
Wifi is off (the airport signal is blank)

I click on airport icon->Turn Airport On, but nothing happens.

I googled around a bit and found one recommended solution where I delete the "automatic" location and create a new one and enable the wifi, or I delete the "AirPort" from the location and add it back, but neither of these resolve the problem. I also called AppleCare and they had me delete /Library/SystemConfiguration and restart, but that hasn't solved the problem. I have to reboot, which is very painful.

Does anyone have any idea of how to solve this?
