wifi doesn't work with IOS 7

I've contacted Apple following this link http://www.apple.com/support/contact/, follow the steps. If your Care Plan has expired click on Exception -> IOS7.

It seems my iPhone 4s had a hardware issue with the WIFI chip. Apple replaced my iPhone without costs and mine had no warranty!

Hope it helps!

I am in Canada. iPhone 4S, iOS 7.0.2.

Experienced the same greyed wifi issue since update.

My phone is out of warranty by more than half a year.

Followed instruction from Apple's knowledge base, all the tricks explained here and in other threads, except the dryer/freezer ones.

Sometimes, immediatly after applying a fix, wifi/bluetooth became enabled, but never more than half an hour.

Yesterday, Oct 5, I followed user Tommeucanyellas recommandation, quoted here.

I chose the right Country, and clicked the following:

iPhone > Service request & Troubleshooting > Restore or update not working as expected.

Then I entered my serial number. Then choose iOS 7 in the next menu.

I chose to schedule a call. The phone rang at the exact scheduled time. Spoke to a first nice and polite representative who asked if I tried the workarounds explained on the Apple knowledge base, as well as backup/restore and reset network settings. Then I've been put on hold for a couple of minutes. When she came back, she transferred me to a senior representative.

The senior representative acknowledged the situation and apologied. Without me asking anything yet, he offered me to make an exception, a free replacement.

To get the new phone, he proposed to

-go to an apple store (this is a 3 hours drive for me)

-I send my phone, when they get it the send a new one.

-They charge my CC, send me a phone, then I have 10 days to send them the faulty one with the box I received my new phone in. Then they undo the CC billing.

I chose the last option of course.

The same day the new phone left the warehouse in PA and is scheduled to arrive at my place by tuesday.

At the end of the conversation I asked if he was aware of the technical issue. He couldnt tell me, but said that was a known issue and some customers were experiencing this.

I must admit I've been pleasantly surprised about the outcome of this issue.

For those not having luck at an AppleStore, I suggest you try this.

Thanks to Tommeucanyellas for bringing this solution out.

Hi guys,

My girlfriend had this problem with her iphone 4S, but I didn't (also on an iphone 4S). I can't explain this.

I have 2 Airport Express and a Time Capsule, and I noticed that my Time Capsule wasn't on up-to-date firmware (7.6.3 needed to be upgraded to 7.6.4). My two Airport expresses were already on 7.6.4 - I guess I just missed out on the time capsule.

Before the Time Capsule firmware upgrade, she couldn't connect to the wifi at all, but after upgrading the firmware to 7.6.4, everything worked a treat. She had also performed the restore etc., but this didn't fix it.

If you have Apple networking equipment and you've taken the ios update, consider using airport utility to make sure you're on latest firmware across all of your networking equipment as one of your vectors for solving this problem.

I have an iphone 4s 16gb that had wifi and blue tooth issues. If you haven't done anything about it, this is my story, which might help some of you. I checked with an Apple call centre agent over the phone and was told that in my case the phone would be replaced under warranty as it is just over 10 months old. I booked an appointment at the genius bar and I took my phone along to the Buchanan Street Glasgow Store and the phone was replaced no problem at all, the staff were excellent. What I managed to find out, that my hardware chip was probably faulty already, but the fault was hidden until the update sending the chip over the edge affecting the wifi and bluetooth. If your phone has either the full warranty or Applecare extended warranty: Call an Apple agent to check if you can get a replacement, Book an appointment at the Genius Bar at your local store, take your phone along, hopefully it should be replaced with a new handset providing there is no other damage to the existing handset. You will get a new handset and the staff should update the software for you before you leave. Make sure before going to the Apple Store that you back everything up either to your computer or icloud so you can get it back. Make sure when you go to the store you know your Apple Id and Password. In my case my problem is resolved

I have read well over a hundred messages over the last few days and I can see the anger and frustration that this problem has caused. I am still disappointed with Apple because the way that this matter is being handled overall. In my opinion, If Apple can do alot of PR for IOS7 on how improved it is, then naturally people will want to download the latest software to there devices to keep up to date. Apple should realise that people spend alot of money on Apple products because of the quality and the brand name, so customers should expect nothing but the best and the products to work. Yes things can go wrong, but if there is a recognised chip error with IOS 7 to Iphones 4s that is only coming to light as a result of the IOS 7 update, then I seriously hope hope that Apple do something about it and look after all their customers. If Apple does not sort this out then they could loose alot of valuable customers to other well known brand names. COME ON APPLE SORT THIS OUT YOU KNOW YOU CAN. On the other side of this, maybe think about investing on Applecare extended warranty, before your main warranty runs out, I know I will be soon. I hope this helps some people and good luck.

This helped me

One of the most common complaints we are hearing from users is that they have been unable to access wi-fi and Bluetooth after installing iOS7.

Here are a few things you can try:

- Change the name of your device

The new operating system seems to have an issue with apostrophes. At least when it comes to wi-fi.

Check out your device name. If it is called something like “Claire’s iPhone” it could be the apostrophe that is causing the problem.

To change your device name go to Settings > General > About > Name. Tap on the name to edit it and remove the apostrophe. Save the change. Switch off your phone and then switch it back on again.

Your wi-fi should be working.

We have no idea why this seems to work but many users in Apple’s community forums have said that it works.

Hey , I want to add what fixed both my Iphone 5 and iPad after the latest updates.

I tried many complicated methods, soft reset, reset network settings in airplane mode, removed apostrophe, reset privacy and location settings, reset router blah blah.

I removed apostrophe but I only had that on one device so not sure that was the ticket but can't do any harm.

Soft reset, press sleep and off button.

Then in this order I did the following.

Choose to forget your home wifi option.

General setting-reset- reset network setting

Turn off phone/iPad (I was doing this on BOTH devices at the same time and it fixed both!)

Turn off router for 5 mins.

Power up phone/iPad and router together but soon as you turn router on hit reset.

Rejoin the network on your devices and add password.

For me, for both devices it fixed the problem.

I was stuck for days with no wifi and trying various methods were useless, can't believe some people put their phone in the freezer but hey, whatever you want!!!

Don't skip a step as outlined above.

Reset that router as soon as you turn it on along with the apple devices before they start searching for it.

And it worked when nothing else would for both devices that were clearly affected by iOS 7 updates.

Do it in that order and I hope you also find you don't need to hard reset or freeze then blow dry your devices!!

Let me know if it worked for anyone!! Fingers x'd for you all!!!

I am not sure fi apple is listing to our isues (or) not? any luck I tried airplan mode and all mentioned in http://support.apple.com/kb/ts1559 no luck

Try this:

- Restore from backup. http://support.apple.com/kb/ht1766 (If you don't have a backup, make one now, then skip to the next step.)

- Restore as new device. http://support.apple.com/kb/HT4137
For this step, do not re-download ANYTHING, and do not sign into your Apple ID.

- Test the issue after each step. If the last one does not resolve the issue, it is likely a hardware problem.

Removing the ' from my iPhone's "name" seemed to solve my wifi problem. I'm running 7.0.2 on an iPhone 5.

My guess is it is not a problem with IOS but the router firmware in the handling of strings. The apostrophe is now properly being sent in the identification string to the router by IOS. The router sees the apostrophe as a single quote mark and searches for the ending quote mark (apostrophe). Such ending quote is never found thus the identification string is not correct and improperly formed according to the router. An apostrophe is not improper in the string, it is just the router that is incorrectly processing the string.

One possible solution is to upgrade your router firmware to the latest revision, or purchase a new router. A lot of advances have been made in the last couple of years with router technology and firmware. You will get a stronger and more robust signal.

Many have had success connecting to more current routers at their work location and public WIFI spots.

I've just spent over an hour on the phone to Apple. They make out that this is not a problem they've really come across. After restoring my phone as a new phone and wifi still greyed out they insist that it's is a hardware problem that was there before the iOS.7 update but the update has bought out????? Makes no sense to me. Anyway in the uk they offer to replace the phone for £146 or if your handset is via a monthly contract they say to contact your network provider, as in the uk the handset is covered by consumer law for 2 years. My provider offer a courtesy handset while my phone gets sent off to be looked at, it will either be repaired or replaced..

Took our broken iPhone 4s into the Apple Store today and they immeidately replaced the phone for free (even though the phone was out of warranty) because the issue is an incompatibility between the WiFi / Bluetooth firmware of some phones and iOS 7. Confirmed my suspicion that this is a software issue, but not one they've solved yet so for now they are replacing phones. The Apple Store Genius Bar person I spoke with had replaced several phones with the exact same issue. He didn't have any information on when an iOS 7 fix was coming. So if you have this problem get the phone replaced for free - in our case none of the workarounds listed worked. Now if only Apple would acknowledge the problem publicly... a small percentage of millions of devices is still a lot of people.

I struggled with this issue for more than a week. Tried every single solution from this thread (except the freezer) - nothing worked. Until I finally decided to erase everything from my iphone and DO NOT RESTORE, but start as NEW PHONE. Then you need to turn the phone off and on again and IT WORKS! (When I restored it, it didn't work).

It is harsh and takes time, as you have to download all your apps again one by one and transfer contacts without connecting to iTunes on your computer. You also lose your iMessages and all data etc (unless there's a way to do backup on iCloud that I don't know about). But I have my wifi connection at last - I've had it for a day now and I hope it would stay (I'll let you know if it doesn't).

There is one more problem - I don't know yet how to synchronise my "new" iphone with my computer without restoring the "old" one. I'll try it soon and see what happens.

All, after being affected with this issue for a few weeks now and monitoring this thread I decided to bit the bullet and call apple support. Despite my phone being out of warranty they made an exception and replaced my phone (had to go into apple store to do the swap).

It is truely sad the way in which apple has handled this situation. The fact that *nobody* from apple support has yet to chime in on this thread is astonishing.

Hopefully my replacement 4S will not suffer the same problem as my previous one but if it does the replacement phone does come with 90 more days of warrenty.

I suspect that no software fix is coming quite possibly because the bug caused hardware damage to the integrated wifi/bluetooth chip in these phones.

Maybe if everyone demands a replacment someone will take notice because it is clearly not happening in this thread.

I'm convinced there's some sort of airplane mode bug in iOS7.

My problems first started on the first flight I took after updating. I used the airplane mode from the quick access tray a few times and poof! Glitches galore. Dozens of hard resets and slew of other troubleshooting didn't work. I tried turning Airplane Mode on (from the quick access tray) and did a network reset. Has worked like a charm for about a month now.

So I tried doing these steps again: Try going to Settings > General > Reset > Reset Network Settings but putting the phone in "airplane mode" first. That seemed to solve the issue for me. Weird.

I may have found a workaround. it took me a while to figure it out, but it seems to be controll center tha'ts causeing the issue. turn controll center off both from lock screen, and from apps, put into airplane mode, and reset network setting. worked for me, just now. hope I can help some people with this.

I have a potential fix.

I could not connect to Wifi when I first set up my iPhone after ios 7 upgrade. I had to restart my router (which is in a unified device with my modem) after disconnecting everything plugged into the router/modem. Then, once the router/modem had completely cycled back up, I inserted my password on the iPhone, and I finally connected. I hope this helps. (I joined the community because after calling on the resource so many times, I'd like to be able to assist someone.) Best wishes.
