This seems to have solved a network problem where, when awaking from the sleep mode, WiFi would not find networks.
Thanks.
Never had a Wi-Fi problem with mine upon reboot or waking from sleep.
You must be holding your PeePee wrong. I mean PeeCee…
After a couple of days on the phone to Apple, they said this was an ongoing problem with many users and they were working on it. So you should keep your hands off your pee-pee for a day or two – give it a rest BLN.
Plus that firmware update failed to fix the problem.
Now I suggested you leave that thing alone, and you’re at it again.
I intermitiently had this issue with reconnect after wake as well. Fingers crossed – downloading now.
Sorry, it does not fix the problem for me. I ‘miss-spoke’, (to quote any politician).
Seems snappy to me! 😀
This seems to have broken the virtualization support in Parallels….
I just installed this update along with a WiFi update – my Mac now only boots into the recovery console.
I did not power cycle the machine (or do anything else, no power outages etc) whilst this update ran.
I did notice an initial long beep when first starting up doing the EFI update which I thought odd at the time, I’m now resinstalling Lion from the recovery console.

The Option key seems to have been stuck after the update! Never had such a problem before (Macbook air, latest OSX). Now I can get the Option key unstuck! Anybody else with the same problem?
