wifi doesn't work with IOS 7

My wife's phone is doing the exact same thing. iPhone 4s 64G and soon as ios7 was installed the battery life has gone down the drain (yes I did all the suggested fixes to cut down on the battery drain), but the battery just drains for no reason. It was at 100% this afternoon and now it is at 23% and the phone has been sitting on the dresser not doing anything. Also the Wifi is greyed out. The phone is mint and has always been in an otter box. I am not going to try to freeze or heat my phone, it is clearly something with the update to ios 7. My wife was so mad about the battery thinking it wa apples way of making people ugrade to a new phone, she went out and bought a Galaxy S4. I am also due for an upgrade and was looking at the 5S, but if Apple is not going to do anything about this, I amy also look to another manufacturer as well after having an 3S, 4 and 2 4S's, 2 ipods, itouch, etc (10 apple devices over the last 4-5 years). This thread is also making the news http://appleinsider.com/articles/13/10/10/ios-7-update-brings-more-wi-fi-issues- for-some-iphone-4s-owners

My wifi button finally gave up and grayed out a couple weeks ago. I tried gverything I could think of except for the stupid idea of putting it in the freezer. No luck.

So I decided that better a frozen phone than a brick and put it in for fifteen minutes (good thing I set a timer, because I had totally forgotten about it by 15 minutes). Brought it out, let it warm up and turned it on, and........ Drumroll please! For the last 12 hours, perfect consistent wifi.

Okay, so maybe not such a stupid idea after all.

Now the question remains: "For how long will this fix last?" I don't know, I'll post again when it dies again, but for now I'll rejoice in a phone that actually works.

I lost wifi connection on my 4S, it is 2years old and had been fine with IOS7 for some time. We took it to Apple and they checked the aerial which was fine and diagnosed a hardware problem. Luckily I was insured so got a brand new replacement with IOS6 on which worked perfectly, foolishly I upgraded to IOS7 and instantly lost the ability to select wifi. This really needs sorting or the ability to revert to IOS6.

iamjpv,

Toggling the wifi router's security first to none, then back to wpa2 AES, and change to a new password.

If that doesn't work, I'd try toggling airplane mode, bluetooth on and off. See if these would help.

Same problem here in Australia.

I have had my iphone 4s for 18 months or so with few problems. Shortly after upgrading to ios 7 I lost wi-fi and bluetooth. I first noticed the problem as I was driving when a phone call arrived and my bluetooth was not connected. Two days later I noticed my wi-fi was not conencted at work or at home.

I went through the support forums and followed all the official advice (thank you for the links to the support information everyone) and then opened a support ticket with apple. After following the intructions I too had no luck and the wi-fi is still greyed out.

I would like to downgrade the ios as the early ios 7 adopter was able to do (previous post) but this is no longer an option. When my car service people upload new engine management software and it fails in some way, they call me back in for an update/fix (I had this situation last year with my peugeot 308 hdi). When you upgrade your iphone ios the first response seems to be that there is now a hardware fault with your phone.

I have now racked up some real costs on my phone plan as a result of no wi-fi connectivity and am interested in class actions in this regard.

To Sandskrit,

My router SSID name is in all capitals and my two iphone5es and ipad2 accepted it ok.

This may be fluke with a particular make and model of router?

But one thing is certain, whenever an idevice has problems joining a network, a good way to troubleshoot would be to change settings back and forth. Such as change SSID name, security type, password, anything to toggle the current state of the router.

for context see my earlier post 10/1/2013

After fiddling around unsuccessfully a bit longer with my family's two iPhone 4s, I went to the local Apple store. I was told I was dealing with hardware problems and since both phone had been purchased recently they gave me two new iPhone 4s. These new iPhone 4s had iOS6 installed and Apple personel updated them to iOS7 in the store while I was waiting. After the software update both new phones had no problems with WiFi and BT, so I became adventurous and decided to also update while in the store the iPhone 4s I use myself for work to iOS7. And it also worked fine. I left the Apple store with 2 new and 1 old iPhone 4s running iOS7 with the feeling that may be it what I had experienced was really related to some early revs of some chip and things would be fine from now on. UNTIL YESTERDAY! My wifes 'new' iPhone 4s, i.e., the new phone I was given in the Apple store, is showing the dreaded greyed out WiFi and BT switch since yesterday. No more WiFi operation at home, the FitBit no longer synchronizes (BT), the hands free in the car no longer works (BT), ...

Given the above, it is most likely just a matter of time until our other two iPhone 4s show the same problem. Can't wait for it ... BTW, so far I have kept our iPad2 and iPad3 on iOS6 ...

And no, nothing changed over the last couple of days. No new iOS downloads. No changes to the networking environment, which actually is irrelevant as the issue is NOT not being able to connect to the network. You simply can't turn WiFi and BT on in the WiFi setting screen!

Something seems fundamentaly broken here. It would be nice to hear at a minimum an acknowledgment of the issue from Apple.

I upgraded a few weeks ago from iOS 6...something to iOS 7.0.0 - nothing special happened. Then a few days later upgraded to 7.0.1, to 7.0.2, to 7.0.3 and yesterday finally to 7.0.4.

I realized that all of a sudded I didn't get contact to any internet address.

I checked the IP config - no IP address - ups - by the SID of my WiFi router is visible

I checked the protocol on the DHCP server - the iPhone didn't send a DHCPREQUEST at all. So, there is no reason for the server to send as an answer an IP address :-) server is doing what he is supposed to do.

If I configure a fixed IP address on my iPhone -> all fine

I would call that (very) poorly tested software

There is basicly _nothing_ on the WiFi (wire :-) )

neither a DHCPDISCOVER nor a DHCPOFFER nor a DHCPREQUEST nor a DHCPACK and so on and so forth ...

I don't wanted to bore you to death with the protocol details but wanted to pointout the issue.

I traced the network using tcpdump on the DHCP server

The iPhone does not request _anything_

Does not get any respons (what would be corect)

No request no answer no IP address since iOS 7.0.4

Same problem here. Can use wifi next to modem but no where else. Tried all solutions - airplane mode, restting all settings, changing modem settings etc. etc.

Luckily my phone was still in warranty and went into store and they've changed the handset. Now works perfectly. They think it is problem with wifi chip.

I am sorry to say it but you will have to wait for a later iOS software update, if all the troubleshooting articles have failed. A newer version (can't bee too specific for obvious reasons) should be coming soon, as this is a major issue. Why not file a bug report if you haven't done so yet, and be specific to your case. https://bugreport.apple.com/

It's not the iOS. It's the hardware. Your hardware was replaced, and the replacement has a 90-day warranty. I suggest that if you are planning to upgrade your iOS at all, then do it soon, to be confident that there are no issues with the replacement.

It's not because of the latest iOS update. If it was, then all units would be affected.

Either pay the out-of-warranty fee ($149 for iPhone 4 and older, $199 for 4S, and $269 for iPhone 5 or newer) or get a new device.

Dear Mr. Deduction aka TJBUSMC1973,

If you read through this thread you will find that Apple has admitted to many the IOS is at fault. Many people, including myslef, have been told by Apple Care representatives that the iPhone 4S is set up with different components than the newer phones. It is a single compent in the 4S that caused phones to overheat, not hold a charge and have oddball problems including the very common, for iPhone 4S, lack of WiFi connectivity. Numerous silly solutions like placing your iPhone in the freezer have resulted. Also, numerous petitions, televisions news stories, class action suits and web threads like this one with 66 pages have resulted.

Now you can continue to be in denial and say that everyone with an iPhone 4S involved in upgrading to IOS 7 is just a sour customer. You can continue to defend Apple's warranty program even when it is Apple that is causing the defect and it's staff admits this. And you can rely on your decades of troubleshooting to come to a logical conclusion a la Spock. Beam me up TJBUSMC1973.

But deductive logic says you are delusional. Everybody on the planet is having problems but, in your mind, they are all crazy and you are the only sane one? Give us a break and find another thread to be the cheerleader for Apple. What we do deduct from your gibberish is that you have not been in touch with reality for a while and your decades of experience are not aiding you in maintaining a grasp on reality.

Apple screwed up. It won't admit it rolled this IOS out too soon. They did so to appease Apple stockholders due to a misplaced and poorly timed promise. They won't admit it now so stockholders won't revolt when hearing of the mistake and the cost and shame it would bring to Apple. In doing so, Apple has completely let down and aliened a huge number of Apple iPhone 4S owners. Apple screwed up, it won't admit it. It won't fix it. It is throwing its 4S customers under the bus and looking toward the future. There are more customers where those iPhone 4S customers came from is the Apple mantra. That is the deductive logic and it is a sad tale about a once trusted company.

Keep living in Dreamland. We're all wrong and you are the only logical thinker in the threead. Have it your way.

Us, we want Apple to fix our useless phones that it broke. This is called fair play. This is called responsibility.

Which is it? Is it the iOS that is at fault, or a component of the 4S? It can't be both. It's either the software or the hardware. Also, since not every iPhone 4S has this issue, and since this issue has been around during iOS 6 and iOS 5, your logic is flawed.

And nowhere has Apple 'admitted' this, at least not officially. At best, an Apple employee may have thrown that out there, but that's not an official Apple response by any means. Additionally, any such accounts listed in this thread are second-hand, anecdotal comments. There are far more accounts of Apple employees telling customers that it is a hardware issue, and they need to replace their devices.

Show me an official statement by an Apple representative that is authorized to make such a statement that indicates it is the operating system. Please. I'm anxiously awaiting your proof.

"Everybody on the planet is having problems with their iPhone 4S"? That's hilarious. Please, provide any kind of proof of that, please.
