IOS 7.1 iphone 4S wifi not available .. help..

I totally agree with you, well explained. I also have this issue with my 4S unfortunately and waiting for iPhone 6 to come out. Hopefully, there won't be any issues regarding this.

I ended having to upgrade my phone 2 weeks ago. The store said the wifi chip was shot. I got the 5s I'm happy now but upset because I wanted to save my upgrade for the next phone. I'm upset that this issue never happened to me before so therefore I should feel lucky but I don't.

So ummm.. if you wound up upgrading anyways, why didn't you just blow a dryer to the top of it and see if it brought back wifi like it has for 100% of us? You had nothing to lose. Seems to me you didn't even read the replies here because otherwise you'd know that AC was bs'ing you about the chip. Oh well once a fool....

I actually have this problem for at least a year now, and I was planning to buy the 5S, but then, we are a few months away for the next generation to be revealed, so I decided to keep the 4S for a couple of more months, then buy 6.

Em contato com a Apple, a mesma informou que para a correção deste problema é cobrado o valor de reparo do 4S no valor de R$549.00. Isso é um absurdo, pois trata-se de uma falha criada com a própria atualização da versão 7.1. Vamos procurar nossos direitos perante a justiça.

I'm having the same prolem, I'm not seeing a ny solutions on this thread. I tried all the resets already.

OMG tell me you aren't serious. There a MANY solutions mentioned in this thread and the one that HAS WORKED FOR MONTHS AND MONTHS is the blow dryer trick. Just blow hot air from a blow dryer into the headphone jack about 2-3 inches away for a tad over 5 mins and wifi comes back on and stays on until ios updates again and just redo the trick. What's so fkn hard? Oh I know, you just felt like responding without reading the thread.

So I tried the blow dryer method and it worked for me too. So untill iPhone 6 comes out, I think I'll do fine.

I have an Iphone 4s and I am having the same issue!! Have tried all solutions mentioned except for the renaming SSID. I am on the latest release of iOS (7.1)... Apple can we please have a fix for this??

Blower+freezer trick helped me to get back my wifi one week ago, but last night, the WIFI gray out again, and I did blower_freezer again then the wifi came back again...I do not know how long it can last! I hated it!

Just got back from local Verizon Store. They knew about the issue!! Seems that iOS 7.1 was really "designed" for the iPhone 5 not the iPhone 4S. Their solution is go back to the old operating system 6. something or just live with it until my upgrade comes in July to upgrade to an iPhone 5 which I am not going to do.... I'll just wait for the iPhone 6 Ugh :-( Learn to live with the lower speeds...

Hi,

did you use control panel in lock screen to switch wifi on/off before it greyed out again ?

I have tried the blow dryer & freezer method, it works for like 2 days & then I have to do it again. It is getting fustrating now

WARNING

Greetings all,

Myself: Iphone 4S (White) running IOS 7.1 - never had any issues with WiFi (through all the IOS upgrade from ios 5x on) - until this morning after the phone for stuck and rebooted.

I followed the hairdreyer trick and just wanted to everybody a heads up:

After aiming the hot air towards to audio jack hole for about 2 minutes (I was moving the hairdreyer around the top of the phone and a little underneath it) I saw what looked like some of the LCD liquid start to run over the top of the display! I stopped immediately and it "seemed to subside/clear/retract back towards the top of the screen. I didn't see any temperature warning.

So please beware: you might not see any "temperature warning" and you could in fact fry your phone.

I'm not sure if IOS7.1 removed that "temperature warning" message, and I'm sure some folks might say the video said "you don't want to melt it - just heat it up" - but it's a fine line, and I would be very careful.

Phone in the fridge at the moment so will give some feedback in about 20 minutes if it did solve the issue (temporarily at least)

EDIT:

The trick seemed to have worked - WiFi back on 🙂 - and LCD in tact.

So just be careful. It's worth saying my phone was heated to such a level that touching it was tricky - so the excessive heat must have "re seated/soldered" any pins - which in my opinion points to hardware. No temp warning, no " hard reset" required, just some heat.
