Tried a few more things without any luck:
- Reset SMC, PRAM and NVRAM
- Deleted /Library/Preferences/com.apple.alf.plist and rebooted
- Changed my ipv6 settings to link local
I've found out that Lion updates the firmware of the Airport card and the Airport utility so i think it has to do with that. I have a Broadcom BCM43 Airport Extreme (0x14E4, 0x88D) card. I don't have AVAST software or a firewall running but even if i did, that won't cause this kind of issues.
Apple really needs to fix this, i can't work without wifi.

Wifi on Lion is DEAD. Won't turn on.
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.

Are you also able to see your Wifi card in System profiler? Click on the apple logo and go to 'about this mac'. Please also give us the name and type of your airport card so that we can find out if it's limited to a few airport cards or more.

Just tried a few more things:
- Deleted all airport related files in /Library/Preferences/
- Deleted all airport related files in my user library
- Did a permissions scan and fix with disk utility
- Verified my disk with disk utility
Nothing has worked for me yet. I really think Apple messed up with the firmware versions. I'm sure that if i'm able to flash the firmware back to the SL firmware it works fine.

I have the same problem with my 2008 unibody MacBook. Have now reverted to 10.6.8 again, can't work without wifi.
Aiport card: AirPort Extreme (0x14E4, 0x8D)
Firmware: Broadcom BCM43xx 1.0 (126.96.36.199.4)
Looks like the same type as yours Kevin.

Yep. Can confirm that Bert. This is the firmware version on Snow Leopard, right? The firmware version on Lion should be 188.8.131.52.6. It seems that more people are having difficulties with Airport under Lion. Connections that are dropping, slow speeds etc... I think that alot of these problems have to do with this firmware fail.

Hi, the same problem here. I upgraded yesterday to Lion an Wi-fi is death. Only during several minutes i could turn on "Wi-fi" and have signal. I've tried the following but nothing happens:
- Restore permissions.
- Reset SMC, PRAM and NVRAM.
- I've created a new location with only the Airport card under System preferences - Network.
- I've made the airport card inactive and active again.
AirPort Extreme (0x14E4, 0x8D)

Macbook Unibody bought in summer 2009, LION upgraded from SL 10.6.8
I supose is a firmware problem... We'll have to wait!!
