Q: wifi doesn't work with IOS 7

I have the same issue, wifi button greyed out, then I reset, then wifi works and goes off after a short while. When I try to go in to wifi settings, the screen freezes! Have tried every solution going to no avail. So I too am adding my name to this thread. Disappointing apple.

Thanks, worked like  charm:-)

Hope they fix this, stupid behaviour

I went to the genius bar today.  they really still think this is a harware issue.  My phone was under warranty so they gave me a new one.  I asked the guy why it happened when i upgraded to 7 if it was a hardware issue.  He said he's seen wifi issues with 4S's before and thought I would have had the same problem soon anyway even if I hadn't have downloaded 7.  Somehow downloading 7 just brought out the problem sooner.

It was lunacy in my oppinion, but i didn't have much motivation to argue while he set up my new phone.  I asked what my options would have been if my phone not been under warranty. I would have had three options:

1. buy a new 4s for $200
2. keep my phone and live without wifi
3. upgrade with my carrier if i was elegible.

I'm really pretty angry with apple on this.  He did forget a fourth option:

  4.  Buy an android phone.  Which would definitely have been on the table if they would have turned me away.  I buy apple products for outstanding performance.  Without that, I have no reason to buy them.  Hopefully someone at apple reads this stuff.

FYI, resetiing my home router fixed my problem.  My iPhone 5 and iPad running IOS7 will both connect now.  I hope you all have the same luck with your issues.

Same issue for me one day after upgrade to IOS 7. I've tryed all tricks mentioned here and no luck with my 4S. Please solve it and make patches in update ASAP.

Hey all...I have an appointment tomorrow at my local genius bar...Have the same issue with my Iphone 4s 16gb.  After updating to iOS7, I totally lost my wifi and cannot turn it back on.  Button on wifi is greyed out. Steps I have taken so far: network reset, hard reset, another network reset with support on the phone, network reset with airplane mode turned on...no go on any of them.  This is there issue and the support reps on the phone even said as much.  If they turn me away for being out of warranty tomorrow, I will not be getting an Iphone in the future...there are still better andriods out there...fix the issue already apple, having to use my data plan for internet all the time is starting to cause my battery to become hot.

Don't even have find my phone on so didn't work either.

Bluetooth works OK, this is a software bug.

This worked for me also

Simillar problem, My IPad was working fine till i upgraded to IOS7, now its unable to connect to my home wifi

I took my 4s to the Genius Bar today too and was told the same thing.... Almost word for word.....Sounds like they're feeding the same answers to everyone. But unfortunately my phone was past the warranty.... Still hoping Apple owns up to this and sends out a fix!

My wifi lasted exactly 3 hours using the keenovision fix. (Disable connection center at lock) I'm done!

@keenovision - thank you for your persistence and time, you should submit an invoice to Apple for troubleshooting their problem! You are a good person.

Really, Apple store is trying to say our phones just happen to brake when we upgraded.. Are you kidding me.. My phone is 1 year and 2 months old.. so I am screwed..

My phone does not have a scratch on it, been in a defender case since day one.. and never been dropped.. Figured it have good resale value if I kept it in good shape.

Does apple even look on this board.. do they really think I will buy that over 100 people's phones all broke right when they upgraded to I0s 7.. Maybe if it was a few people.

But not this many people..

If apple does not address this,, I am thnking class action law suit. I be damned if before I will give them a penny.

Worked after setting the router to "Setting the Router to this mode will let 802.11n-, 802.11g-, and 802.11b-compliant devices to join the network"

I have tried each fix, apple seem to be in complete denial, told me my phone is broke. Yet it can connect to wifi just for a short while!

You're lucky, mine won't even give the option of turning on WiFi.

I can't exactly ask every hotspot providor and our company to change their WiFi settings or try switching it off and on again.

Come on Apply disengage digit and fix the bug!
