Had always had a weird issue with Airport/Wifi on this laptop, 2.93 duo. If I would turn off Airport, then turn it back on the machine would freeze. Often when starting up it would freeze (verbose logging startup seemed to point to an Airport issue). Then other times it would start up no problem and Airport would be on. Today installed Lion. Airport was working fine, was doing emails, browsing. Updated Little Snitch and did a re-start. Since then I cannot get Wifi to turn on. Have disabled LS, thinking that might be the prob. I choose "Turn on Wifi" and nothing happens. In system prefs it won't turn on there either. Click the button and nothing happens. Have deleted the Wifi out of the interface box and re-added it, thinking that might fix it. Nope. Under 10.6.8 that interface was called Airport, now under 10.7 it's called Wifi...weird. Is that something Apple changed? Someone please help. Airport/Wifi is dead on my MBP with Lion.
