    I updated using usb cable to laptop and itunes on the laptop. Have experienced greyed out none working wi fi button, not seeing my own network, a network asking for my apple p-word, all of these things at different times today. Then magically my network was there to be recognized, acted normally for awhile... and the next time I looked, it was all gone and I am back to the greyed out none working wi fi button and out of ideas :-(

    I tried everything also. I restored to factory settings and still nothing. I can't even "Start Using Your iPhone" because I can't sign in with my Apple ID. It says there is an error with the server or something. I'm about to go to the store where I bought my phone and maybe get another one. I just don't know what else to do.

    I have WIFI grayed out right after IOS6 upgrade. no physical damage to phone. Soft hard restore / restart did not fix problem. I am very unhappy with such upgrade problem.

    Sorry, didn't work on a Verizon 4S.  Still grayed out for me.  I would love to go back to 5.1

    I just want to add something here.  First, there appears to be different wifi problems.  My problem is simply - I cannot turn the wifi on.  The wifi switch is grayed out.  Turning off the carrier date does nothing for me.  The switch is still grayed out.  Now, this happened yesterday when I updated both my Verizon 4S to iOS 6 and a non carrier iPad 2.  No problems with the iPad, that works just fine.  But not the iPhone.

    Turn off iphone, open itunes then connect iphone with usb and hold power and home button for 10 seconds, let go of power button keeping home button pressed til itunes recognises iphone in recovery mode. Then hold shift down and press restore, you need then to find the ispw 5.1.1 file and pick that press ok and it will downgrade.

    I agree there are two issues.  The first is that wifi won't turn on.  The second is that data does work.  Hopefully 6.01 will be out soon (I assume they are working on it by now) and we will all be happy again.

    Did a quick search to figure out if this was a network related issue that may have triggered this orginally, rather than a purely software related issue.

     

    Pretty interesting signal to noise issue on this specific problem.

     

    There was a Tweet  that IOS checks to see if it can reach a certain test site at Apple and claimed that it was apparently not-reachable during the upgrade process, but is now reachable.

     

    http://www.apple.com/library/test/success.html

     

     

    The person that figured this out probably did a fairly basic network (but non consumer) test, i.e. looked at the network traffic going between his device and Apple, probably by hooking up the usb to his Mac, and monitoring the traffic using a traffic analyis tool to see if the program was getting the right thing on the Apple end.

     

    If you have watched the entire download and reboot process it is fairly complex, and involves verification of the downloaded upgrade, that verification is based on having a valid set of credentials on the phone such as a Apple digital certificate.

     

    At one point Apple discovered and patched  a fairly large mistake, an IOS security hole in which the installed  iPhone digital certificates could be used to sign additional certificates that would validate any software to load onto an iPhone..They did not apply the same patch to older iPhone 3 models.

     

    A similar thing recently  hit Microsoft and is being fixed. Generally no people look at this data, but software does and you shouldn't have to check this.

     

    This kind of network debugging is far beyond what can be offered at the Genius support level, and if this is actually the case, (and that the site was somehow down, and required, and obviously now working) it might break the automated install, but would work after a restore after they brought the site back up.

     

    Since many people fixed this doing one of the many restore options, and others got their phones replaced with 5.1 installed there's probably some people that a full restore and it still failed.

     

    But did they do a DFU restore? That's about as far as one can go. My guess is they did a restore, but not at that level.

     

    That's going to be the more interesting case (since many people have already fixed this), and then I would wonder if the software "hung" at a certain spot, but the fact is that if one got a valid software image, i.e. properly signed from Apple, it would either be rejected, or accepted as coming from Apple.

     

    While it could be a software glitch, with a patch issued at some point,  there also the outside possibility with a network upgrade to  hit  a site which could load a slightly modified image that could possibly run, but was not actually Apple signed.

     

    This is essentially true with any operating system software, and there are companies out there currently who sell the ability to load compromised software onto phones.

     

    The only way that verification check can take properly  place if for the device to check the digital  software code signing signature, and the only way to make sure you have the entire security chain working at the most basic level is to start off from the device firmware update state which validates the underlying security model for accepting new software.
