wifi doesn't work with IOS 7

Hi,

I reset my router and my phone is working fine been almost a day now. I have my HP laptop and iPad first generation hooked up to wifi as well. I did the reset and everything is still working fine. My laptop was all messed up during the download of IOS 7 but has been working fine since I reset my router. It's worth a shot...good luck!

I left my phone in airplane mode when I went to bed, then when I woke up and switched my airplane mode off , the wifi suddenly started to work, it picked up my wifi , it did stutter for around ten mins and since then it has been ok.

Weird.

i tried almost every trick mentioned nothing seemed to work and i was sure it was a hardware problem. Try going to icloud in settings and turning off find my iphone and do a hard restart. After my phone restarted everything was working again both my wifi and bluetooth and find my iphone was on again on its own. Hope it helps

Yes, iPhone 5 IOS 7, WIFI has been working since rebooting my router; (turnning off wait 10 sec. turn back on). I think about 3+ days now. Only issue was not connecting or loosing connection after the 6 to 7 upgrade. Every thing seems to be fine now.

From the beginning I assumed this was a software problem as it occurred within hours after I upgraded to iOS 7. However, I went to the Genius Bar (Tuesday evening, 9/24) and they issued me a new 4S free of charge (note: I purchased apple care w/my original phone). Prior to leaving the store they made sure I was able to connect to wifi. I have not had a problem with wifi anywhere since I was issued a new phone. I guess at this point I feel it's a hardware / software combination bug. Either way, if you are still covered under apple care I would recommend just going into the apple store and getting a new phone.

Just a thought - if this is your home wifi connection, try shutting down the internet cable box (or whatever device/means you use to get to the internet), and also your wifi router. Wait the usual 10 seconds and turn them all back on and see if that helps....

I used to have this headache a few months ago with it recurring every other day. Every other device at home had no problem, but my iPad and my sons used to choke regularly.

No real solution to my problem - it just decided to stop its problems on its own.

I went into my router settings and changed my password and changed my security settings to wpa personal and my i phone works on wifi now-I tried all the posts on here and nothing worked -2 minutes on my router settings and i have wifi on my phone -I dont know if you have to change the wpa security or not i just did it- i think it was just the password-Good luck all

Oh Im not saying there isn't a problem. There usually is issues with any updates, be it Xbox or Computers or Iphones.... Ive updated my own stuff, along with other peoples many times and sometimes OTA has been not as reliable. One example just recently is that I was updating an Ipad 3 that I gave to my Dad. The OTA update he installed worked, but opening apps or just scrolling in the settings was a bit buggy(slowwwww). I saved a backup and did it through the computer. Corrected the problems.

The wifi thing, I dont know. I haven't experienced it. I was just weighing in that if you are experiencing anything on a software update. I would do a reset fresh on Itunes through the computer. Usually that can correct most things.

Thats all 🙂

I just got off the phone with AT & T and they said that as of about 10:30 EST, Apple has reported a "bug" with IOS 7 and wifi. There is no estimated day or time for the repair but Apple is working on a fix. I've reset my settings, etc. and lost data and this is extremely frustrating.

Let me sum up my observations in this discussion.

Everyone having a problem in this discussion has the following problem:

• All phone affected are IPhone 4s
• All problems occured after the upgrade to iOS7
• The issue we are experiencing is a greyed out WiFI button, which was not greyed out before.
• We have tried all options advised by Apple to resolve this issue.
• we are all unable to solve this problem ourselves constructively, although some of us have managed adhoc 'fixes' like hairdryers or using the fridge to 'cool off' the wifi chip.
• Our iPhone 4s's were operating without any noticable problems prior to the upgrade to iOS7

The above makes me to draw the following conclusion:

There is a clear pattern and these are obviously not individual cases. It appears the wifi chip of the iPhone 4s is being of a substandard quality and not being not fully compatible with the new iOS firmware which causes this problem. Also most of the beta testing over the past months was done using the iPhone 5 and not the iPhone 4 or iPhone 4s. Mostlikely because the 4 series were not part of the large scale testing Apple was not fully aware of this accelerated issue with the Wifi chip (when you do a Google search on "iPhone greyed out wifi" you see that this issue is not new, and you see the issue involves mostly the 4s ) But it seems iOS 7 pushed these weak and thus unreliable wifi chips just over the edge, causing them to overheat and thus to stop functioning alltogether.

Apple must be fully aware of this issue by now but they are incredibly silent in communicating with their in my estimation 'multiple thousands' of customers worldwide experiencing this problem. Apple only sticks by claiming the upgrade to iOS7 is "at your own risk" (that's what I was told) and sticking to the warranty period

(I bought my iPhone in Aug 2012, so am out of Apple warranty)

I feel that Apple should take their responsibility and help her customers in solving this quality issue.

As customers in good faith we bought this product (I paid some €600) having trust in Apple and in the faith the quality would be such that we could use it -with good care of course- for at least 2, 3 or even 4 years.

But unknown to her trusting consumers Apple created a product using a faulty wifi chip (hence the overheating issues which can eventually lead to failure)

As result of this us, we, customers are now stuck with an unusuable iPhone for which we paid plenty of money.

( One thing I am sure of, if Apple would be a car manufacturer or an airplane manufacturer they would never get away with this, and would be forced to do a recall)

My message to Apple:

It is now time to act. Taking responsiblilty never hurts (even if you for some reason feel you are not fully to blame) It gives you credit. And credit gives you loyal customers.

Thank you.

and btw my initial response was for Bin Kroon's nicely done summary in page 27:

To quote Mr Kroon:

• All phone affected are IPhone 4s
• All problems occured after the upgrade to iOS7
• The issue we are experiencing is a greyed out WiFI button, which was not greyed out before.
• We have tried all options advised by Apple to resolve this issue.
• we are all unable to solve this problem ourselves constructively, although some of us have managed adhoc 'fixes' like hairdryers or using the fridge to 'cool off' the wifi chip.
• Our iPhone 4s's were operating without any noticable problems prior to the upgrade to iOS7

i just found it interesting that point #2 would have been true for me if i jumped on ios 7 immediately. we had no WiFi issues prior to last week, and that would have been the most obvious culprit to me as well.

Other than the fact this happened to me on 6.1.3 instead of 7.0.x, I practically agree with Bin Kroon that this is a hardware problem.

I have been banging my head for hours on this **** issue.

Nothing i did fixed the issue.

Until i tried this.......!

In my routers LAN setup i decided to try and set up an address reservation for an address at the very highest range of available IP addresses. This is the range of IP addresses supplied by the DHCP server on your router. On your router you should be able to allocate an IP and link it to the MAC address of your device so it always connects on this IP address and has no conflict. For mine i set it to the highest value i had in my range which was 192.168.0.254 and attributed it to the MAC address of my ipad and voila!

It workd fine 🙂

I hope this helps someone 🙂

I apologise if someone has already posted this solution but i got frustrated after the first 20 pages of this post 🙂

Believe it or not........

I had the greyed out wifi button and malfunctioning bluetooth on my daughters 4S and read this forum.

I tried changing the phones name and doing a network reset and a full reset. No change.....

I then out of desperation, not believing it could work, tried the freezer for 15 mknutes technique mentioned below.

1. Switch off phone.

2. Seal phone in a waterproof bag.

3. Place phone (inside the bag) into the freezer.

4. Leave for 15 minutes.

5. Remove from freezer.

6. Take phone out of the bag and switch on.

Hey presto....fully functioning wifi and bluetooth.

How long for remains to be seen.

I have used the freezer method twice now. First time it worked OK for several days. Because the freezer method works, I feel quite confident that it is indeed a hardware problem with the WiFi chip used in the 4S. I also would not be surprised to find out that all the 4s's with this [problem were assembled during the same production run with the same chip from the same vendor's production run. Here is why I think that.

Remember, I phones generate a lot of heat. Most of us don't feel it due to the various cases we use. As metal heats, it expands. A key filament in the WiFi chip expands with the heat and ruptures causing the WiFi chip to no longer function. Placing it in the freezer causes the metal filament to contract thereby restoring the contact necessary for the chip to work properly until heats causes the filament to loose contact again. I don't know how many times this refreezing process will work until it no longer is effective.

What I learned is that Apple iPhones should come with al least a 2 year warranty. It is possible that Apple knew about this problem and chose to ignore it. It is also possible that this was a deliberate planned obsolence project to ensure more sales of the newer products...but I think that is highly unlikely. They definitely should institute a Six Sigma process in the plant that manufactured this line.

I do think the iOS7 introduction and this hardware problem are not a cause and effect situation, but merely a coincidence.

It is like the typical 'cult' situation, they can lap up the love, but can't hack the criticism!

Since venting on here, I did the 'turn everything on and off three times and back on' and now it's working!!! lol *touches wood frantically*
