wifi: no hardware found after 10.7.4 update

Hi -

After I did the 10.7.4 update on my mid-2010 macbook pro core i7 this evening, my wifi adapter/internet is not working, it is grayed out and says "no wifi hardware found". I have re-booted my machine 4-5 times but that did not help.

Apparently, if I boot into recovery partition via holding Cmd+R > there my wifi is working and is properly connected. Infact, I am writing this message through that receovery partition safari window connected to wifi just fine.

Another weird nothing I noticed is if I boot into the Safari-only Guest User account, there also wifi is working just fine, no problem.

However, in both of my user accounts, it is giving me this "no wifi hardware found" error and won't connect to internet. In fact, ethernet wasn't working as well in user accounts.

Any suggestions besides taking to apple store?

MacBook Pro, Mac OS X (10.6.7), 8GB, 500GB, core-i7, late 2010

Can you paste your kernel.log here after a reboot ? It can point to some reason as to why this occured. Did it work well on 10.7.3 ?

Make a backup of your system and make a fresh installation of 10.7.4.

Likewise, I can't really post my whole kernel.log but at boot time I do see it refuse to load some kexts versioned 11.4 because an 11.3 module is already loaded.

Being that Mach 11 came out with Lion I'm assuming that 11.4 would be the 10.7.4 version of the module and 11.3 would be the 10.7.3 ?

Ideas for how to defer or stop the first load of the 11.3 module? Or i'm barking up the wrong tree?

Does your WIFI works when you start from the Recovery HD ?
If yes then I would recommend you that you reinstall Mac OS X.

If you doesn't like to do it. You can also try a fresh installation on an external hard disk or 2nd partition and test there.

How do I boot from the second HD?

I already created a second encrypted volume because I need my code on a case sensitive FS so I'm backing up to there.

Just checking I still have the keys to all encrytped volumes..

When you created a 2nd parition, then start from Recovery HD. There click on "reinstall Mac OS X", there you can choose where you want to install the Mac OS X. In this case on the 2nd partition.

YES, my wifi works in Recovery HD mode just fine.

My wifi even works in Guest user Safari-only account as well, just fine.

It DOES not however work in any of the two user accounts, it is grayed out and says "wifi: no hardware found". So it can't be a hardware issue since it is working perfectly in the above two cases.

Something in the 10.7.4. update screwed it up. I do have filevault 2 ON but that should not matter.

I REFUSE TO RE-INSTALL OPERATING SYSTEM, this is silly to have to re-install OSX Lion for issues like this, there is got to be another way out.

I have taken a genius bar appointment today and see what can they do for me.

I had the same problem, I changed my hosts file to original one and it fixed the problem

The same thing happened to me after 10.7.4 update. That's really disappointing: what did I do wrong? I just updated my OS. Recovery HD has wifi though. Restoring /etc/hosts file didn't help.

Same symptoms of non-working WiFi on my used-to-be-working-just-fine-with-10.7.3 2008 Aluminum Mac, with FileVault on.

I restarted under guest, WiFi was working.

I shut down the Mac, booting back up as myself... and WiFi was back.

The hick-up seems to be happening around

I just solved my problem by disabling FileVault (it was enabled when I updated and the problem appeared). After disabling it, I restart my Mac and WiFi was working again. I didn't need to reinstall Mac OS.

I'm reinstalling now.

When I configured OSX I sanely put my music and code on seperate paritions to the core OS so if something like this happened I woulkdn't lose anything.

OSX claims that it "Can't boot from" the old parititon even after formatting it, and the disk utility in the installer is crippled and won't let me alter the partitions.

I've had to hose the entire disk and start over. Pretty spectacularly unhappy about this.
