wifi doesn't work with IOS 7

Same problem with my iphone 4s after ios7 upgade. Did the airplane mode - reset network settings fix. Seems to have sorted the issue for now. before that i was told by apple tec help that it was an hardware problem and i would need to pay for a repair! Come on apple not what I expect from you!!

I tried absolutely everything mentioned on this and other threads. Yesterday, just feeling crazy I tried once more turning on the airplane mode, turning off the control center, resetting the network, and turning on the notification to join networks. The airplane mode on / off "switch" froze for a while afterward but then seemed to recover. After that, I was asked if I wanted to join my office network, and it actually worked (for the first time). When I went home it asked if I wanted to join my home network, and again it worked. When I left and returned home, it automatically re-joined the network, and it did the same at my office today. So -- fingers crossed -- it seems to be working as before the update (note: I never had my wifi button grayed out and my bluetooth always worked).

Still, there are some very strange issues that still occur. For example, if I launch Safari, there are times it starts and then suddenly just returns to my main phone screen. Other applications similarly shut down from time to time for now reason. But, those instances thusfar are not all that frequent and are tolerable.

There is no way these issues are hardware related -- too many different devices mentioned by others (4S, 5, iPads, etc.) and too coincidental occuring only after an update. And, it's nonsense that the update could cause hardware failures in all those devices (or else Apple products are really just too precious to be relied on).

I tried this and it seemed to work.

1. Turn OFF find my phone
2. turn ON airplane mode
3. Do a master reset

   push top button and home button at the same time until the apple appears.

4. turn airplane mode OFF
5. my wifi immediatley came on
6. Whoot whoot

Hmm, this problem seems to have appeared in the beta period

One of the messages in that thread talks about iCloud Keychain

"iCloud Keychain is the culprit for me.

I tried turning this function on again, went through all the steps and then got home and it had difficulty connecting and then I had to select it and the password was gone. I did not have this problem for all the days I had iCloud Keychain off. So, I turned iCloud Keychain off and, after getting on wifi w/password and such, back to normal.

This is the first iteration of iCloud Keychain, so I'm sure it'll improve in future beta releases, I'm staying away from it myself, will try again in beta 3 (next week!)"

I'm going to try that. By the way, my iPhone4s seems fine, but my iPad (latest generation) is experiencing the problem.

My iphone 5 began to access the home WiFi network after rebooting the router. Had all the same connection issues after uploading IOS 7. Tired several of the folk-programming ideas, non-of which worked for over a few minnutes. Now have IOS 7.02 and wifi has been on line using several WIFI spots for 5+ days now.

I've had the same problem. Tried many things you proposed, but what worked for me was this: I disabled Control Center, turned on the airplane mode and Do not disturb mode and then did the hard reboot of the phone. After that I got the connection. I hesitated whether to turn on the control panel again, but I did and it is still working. Hopefully it'll be all right now.

It will not work with this router no matter what I do. I attached another router to my wifi point and went thought that and it works fine now. Same problem with appleTV. I have fios and their action tech router. I piggybacked an old apple router out the back. I think it an ios7 conflict cause my pc and laptops connect fine just not my updated iPhone 5 ios7 and Apple TV. They need to fix it but this is my work around

same here my wifi is greyed out wont even come on they ruined my phoone

Have you tried ANY of the troubleshooting steps in http://support.apple.com/kb/ts1559 or http://support.apple.com/kb/ts1398 ?

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!

iphone 4 uk o2. updated to ios 7.00 no wifi issues. updated to 7.02. instantly wifi stopped working. not greyed out just couldnt find any networks. tried network reset did not fix. tried soft reset did not fix. tried airplane mode on off did not fix.

then removed apostrophe from phone name, reset network settings. wifi then showed networks but would not remain connected, intermittently switching on and off wifi to home network. "forget this network" wifi off, wifi on, reconnect. so far working correctly.

also, read the whole thread first. just because it doesnt happen to everyone doesnt mean it doesn't exist. something must be changing in background but not affecting everyone. if i'd have spoken to apple pretty sure they would have told me hardware issue too even though following the suggestions posted by people here seems to have fixed problem for now. everything worked fine for 3 years before 7.02. good luck to people who have same issue. almost gave up hope myself but messing withe settings in different ways will hopefully ix.

i did not reset my router once during my 5 hour troubleshoot

Hi DfwTex,

Please may I ask a followup qquestion - after the freezer trick got wifi button back, did it stay working?

Or did it revert back into greyed out state again?

This issue is so confusing!

Phone: 4S

Lost all Wi-Fi connectivity after istalling ios 7.

Wi-Fi not grayed out.

I reset the phone twice, reset wifi network settings multiple times. Apple support told me they would repair it for $199.00. After 10 days traying everything I decided to do what some people were saying. Turned wifi off, turned the phone off and put it in the freezer for 10 minutes, turned the phone back on and then the wifi came back 100%, it has been 5 days an it is still working like new. I know it does not make sense, I tried it because I had tried everything else. I called apple support to let them know, left a message with my case number, they have not call me back.

I don't think the WiFi issue is just with the 4S model. I have the iPhone 5 and every since I upgraded to iOS7 my WiFi does not work properly.

Here is my problem. If I have Bluetooth turned on my WiFi will not work properly, will not keep a consistent connection. If I turn bluetooth off, the WiFi works perfect as it did before. I have reset my phone back to factory settings and set the phone up as a new phone in iTunes, still the problem exists.

My phone worked fine with iOS6, but since I upgraded to iOS7, I now have WiFi problems. I should be able to have both WiFi and Bluetooth turned on at the same time and my phone should work with no problems. I should NOT have to have one or the other off.

For the person earlier in this thread that kept saying it's not a iOS7 problem because then everyones phone would be having the same issue, it's hardware problem, that's a bunch of cr@p. If you have a PC running Windows 7 and has a bad graphic card in it, installing Windows 8 on the computer is not going to fix the hardware. If that computer was working fine with Windows 7, then you install Windows 8 and all of a sudden the graphics are messed up, that's a problem with the software and that's the problem everyone is having. If the hardware is bad, then WiFi wouldn't work at all regardless which iOS the phone is running.

The problem is, not all iPhones are made exactly the same. When the iPhone 4S came out many people complained that the displays had a yellowish hue to them while other 4S phones had the same blueish tent that previous iPhone models had. I had one of the yellowish hue displays. It wasn't bad hardware, but the yellowish hue displays came from a different manufacture than the others. I think we have the same situation going on here with iOS7 and WiFi. The WiFi antennas in all iPhones are not exactly the same. The antennas themselves work fine, but iOS7 is not configured properly to work with all the antennas.

All I know is, my phone worked fine with iOS6, now that I have iOS7, and even after I reset my phone and set it up as a new device, having Bluetooth turned ON makes my WiFi not work properly That is NOT a hardware problem, that is a software problem, that problem is iOS7 !!!!!!

Don't give up. Keep on calling Apple and let them know of your issue. I don't know if Apple is finally listening or what the reason is but Apple replaced my out of warranty phone just yesterday after talking with a Apple Care Representative.

After about 4 weeks of my wifi and bluetooth not working on my 4s immediately after upgrading to iOS 7 and about 4 conversations with Apple Care and 5 Apple Store representatives who did nothing. On my final call with Apple Care Rep they finally agreed to replace my phone.

Keep calling and let them know of your problem. Don't give up!

I had delayed updating IOS for a number of weeks due to travel commitment and then when I went to 7.0.3 I experienced the same problem as described here with greyed out wifi, not resolved by changing 'apostrophes, resetting phone etc.

Well after being told that UK Apple would want to charge £146 + for a hardware repair on the basis that the fault was a hardware problem that coincindentaly occurred when I upated IOS with no clear supporting evidence.

I thought I have nothing to lose and made a decision that the only suggestion recorded above I had not attempted was a stint in the Fridge. Well I will be amazed the wifi function has fully returned and is now 24 hours later with out an issue. I can only imagine that the IOS install is overheating the WIFI chip.

I am apalled by the lack of engagement by Apple for what seems to have been a simple solution to try. I have had to reset phone probably for no gain.

coming to the end of my contract and will seriously take this attitude into account on next phone.

Hello Mitbags13,

Apple usually has a very high customer satisfaction rate. I am sorry to hear your account of things.

This matter is NOT a "hardware failure". Your "coincidence" is no differnet from our multiple examples of the same problem. It is simply not concievable that multiple units would develop an identical fault and it be a hardware fault on all units.

I popped down to my local Apple Store with and explained that the firmware update had irreversibly disabled the WiFi an BlueTooth capability. I explained that all "soft reset" and "hard resets" had already been attempted along with full restores. The Apple Rep' appreciated we know our products.

Apple could not have been more helpful. On explaining this to the Rep' he swapped out our units for new replacements instantly.

The service and the attitude of Apple was first class.

Perhaps you might visit your local Apple Store [not a Reseller]. Things may work out fine.

I hope you resolve your issue as we did.

Enjoy.
