Apple delivers Airport Utility Update

Ever since installing this update, my MacBook Pro has been unable to connect to the internet, although it can connect to my airport network just fine. My iMac (not updated yet, and won't be until I get this fixed) can get internet, it's on the same network. I've tried rebooting all three devices (MBP, iMac, Airport Express) to no avail.

Anyone else getting this problem/Know how to fix it?

3 new updates just dropped
idvd etc

I was befuddled after returning from a short vacation only to find the our Apples could not access the internet, my list of networks were invisible and nothing seemed to work. I turned everything off and on, although I did not hard reset my Airport base station. Meantime, I ended up hard wiring my MacBook to my cable modem just to hook up. Apple help told me to restart the modem. It would seem that they would know the fix to an update problem.

@JP: I forgot one single detail. After I upgraded the firmware, the AEBS (Airport Extreme Base Station) wouldn't restart itself. So I did a hard reset to factory settings (holding the reset button while pluging the AEBS to the power, for about 10 seconds or until the light flashed). then configured it with no security, then reconfigured it with the security and then the rest as it was told at first.
Then again, I'm not absolutely positive about how it worked with the windows machine... I'll keep you informed.

Cheers!

Might be a coincidence, but I had to manually restart my airport extreme after this update ran. None of my Macs would connect to it, despite the green light indicating that all was well.

All is fine now, but probably worth pointing out as it's never happened to me before.

Francisco: Wow that's kind of wacky. I just tried what you did (updating everything, setting "no security" etc.) and no joy. So I downgraded again to previous firmware which is my happy place.

Johnny: Agree.

Everyone: If you suffer this issue too, please do file the bug report (link above) in hopes of encouraging a fix. Zillion thanks to all.

JP:
I tried again with the new airport utility. Same feedback but this time, I thought what if I after I install the update, install the firmware update (which is by now like 3 months old) and configure it with minimum settings (no security for instance). It worked. Then I went back to Airport Utility and configured the network again (WPA2 this time) and it worked again. Then put my MobileMe info... and it worked fine.
Shall I say the update to the airport utility fixed my problem or it was the way I installed the firmware that made it, I'm not sure. Will see how it behaves during testing in windows machines but for now, it's quite stable with both iphone and mac.

I hope that with this update I can update my airport extreme (gigabit ethernet) base station to the latest firmware. Anyone with the same problem?

so.... crappy fixes eh?
