Q: iOS 6.0.1 WiFi Still Greyed Out

Hi All,

FIrst of all.  I am in the same boat as 75% of you. 

iPhone 4s just out of warranty

iPhone 4S updated to 6.0.1

iPhone 4S's wifi greyed out.

iPhone 4S taken to the store. Extremely bad Genius bar experience.  Upsell to 199 phone. Recommendation to upgrade to 5 at full price to get a full year warranty vs. the 90 day with 199$ phone.  General apathy, brusqueness and a "want fries with that?" attitude.

iPhone 4S lack of wifi racking up Data Bills

I am hesitant to stick the phone in the freezer or against the heater.  However I did noticed several temperature related alerts on the Usage and diagnostics on a fresh install of iOS 6.0.1 indicating a high temperature after 4-6 hours of install as a fresh iphone.  No restore from backup.

My comments from that experience are in the post pasted below. I believe it is a software bug where the temp readings are not calibrating properly and indicatinga  high temperature to disable wifi. Freezing and Heating the phones resets the calibration for a while and the problem comes back again.

Hope this helps.  This problem is in a class of it's own where actions are required to show the electronics makers that while they may not be breaking the law, the mass exodus of users should make them tremble in their suits. May 35th!!!

Point taken... But it doesnt explain this thread. Warranty active or not..

If putting it in the freezer fixed it, it's a hardware fault. A poor/broken connection somewhere inside the phone. It's simple physics. You can not fix a software problem by altering the temperature of the device.

That would be a great point if low-level software was not a thing.

If this is a hardware fault, how do you explain the fact that it started affecting lots of users immediately after the iOS 6 update?  Planned obsolescence?

Interesting.

The one from iHandy

I just got off the phone with a senior support manager... He stated it may have been an underlying hardware issue before the update and that the update "capitalized" on this issue. So basically they sold me a defective phone and since I'm 23 days over my warranty, my ONLY option is to pay the 199 to get it replaced. Some lvel of support I tell ya................ Though the only difference form working to not working is io6!

So did you do the fresh restore notice the diag data for temperature abberations?

People keep arguing its hardware because freezer method works - I haven't tried it - or found the description of how to do it, but I will say this, my phone is often very hot and I don't remember that being the case before???

So maybe the freezer issue is just helping cool off a hot phone that then temporarily behaves in the same way that sometimes running the battery down and doing a hard reset also helps now and then

I've done the freezer thing and it worked temporarily but I've also let the phone completley drain and waited till the next morning to charge it and try again, that didn't work. Which technically the phone should have been cooler because it wasn't on for long. So I don't know if it's heat, but yet the freezer works. All I know is that my wifi is still out and Apple only wants me to pay for a replacement which I'm not....

DJ,

Have you checked on the new restore and temperature readings under diagnostics.

Thanks

Where exactly would I see a reading?

Settings .. General -- About -- Diagnostics&Usage

Yes Ive checked that. I see nothing about heat or temperature. I see some crash reports of some apps. Is it somewhere specific?

In entries which begin with awdd or log.

I see nothing. Under diagnostic & usage I only see some istrobe, facebook, reset counter, siri and low battery plists. I see nothing with what you said,
