IPhone 4 can't find wifi - have to reboot

Hi, all. I've been having intermittent problems for the last month at least (maybe two months) where for no apparent reason, my iPhone 4 can't find any wifi networks. I've been updating my phone as soon my Macbook Air tells me a new iOS version has come out, and I'm currently running 5.0.1 I have found that 100% of the time, if I reboot the phone, it can find wifi immediately upon restart. Sometimes I'll go a week or two without the problem; other times it recurs within four days.
Any ideas for solving this issue would be greatly appreciated!
Sandy

Unfortunately, I had to reboot the phone last night, so resetting the network settings did not solve my problem.
Still looking for a solution.

Iphone 4 Can't "find" Wifi

Hey all. I had an iPhone 3gs with iOS 4 installed, and it was able to connect to my wifi network.
When I bought the iPhone 4, it can no longer connect to my wifi.
For reference, MAC filtering is NOT on.
Also, I am NOT broadcasting the SSID of my wifi network.
In short, the iPhone 3gs was able to connect regardless of the network name not broadcasting, whereas the iPhone 4 simply states it cannot find my network.
Any tips?

You say you're not broadcasting the SSID of your home network (no real reason not to since anyone with Netstumbler or the ability to read a wireless packet capture can find your SSID in seconds)... did you manually add in your home wireless network on the iPhone 4?
If you did and you're still having problems, have you picked the correct security method, spelled the SSID correctly, and entered in the correct pre-shared key or whatever you're using to secure your wireless network?

HT5569 My iphone 4s can not find wifi after updating to iOS 7.0.4.

I went to the Apple Store today and explained what is wrong with my phone, they didn't even bother checking it, they said I need a replacement for £150, as it's in Apple T&C's that they are not liable if a phone breaks because of an update. My phone was working perfectly fine before I updated with iOS 7.0.4, how can Apple now not take the responsibilty of fixing their mistakes. When will we receive a fix, I have tried every suggestion possible and still no wifi!! HELP..

iPhone 4S: I have the same problem. After updating to iOS 7, wifi worked for some time, and then it stopped working. I can't even enable wifi. I just updated to iOS 7.0.2 and it didn't help at all.

IPhone 6 screen freezes and can't find wifi after iOS 8.0.2 update

iPhone 6 screen freezes and can't find wifi after iOS 8.0.2 update. Have to do a hard reboot. I am Extremely disappointed and lost ALL trust in Apples Quality Assurance. From now on I'll wait a week before I update.

Hey there Shortos,
It sounds like your phone touchscreen is not consistently working for you after updating to iOS 8. I can see how that would be pretty frustrating. It sounds to me like this could be a software issue or an issue with the screen itself. I would start with the troubleshooting in the following article to help troubleshoot the screen itself:
iPhone, iPad, iPod touch: Troubleshooting touchscreen response
Restart your device
Hold the On/Off button until "slide to power off" appears. Slide to power off your device. When it is off, press the On/Off button to turn it back on.
If you can't restart your device, reset it by pressing and holding the Sleep/Wake button and the Home button at the same time for a least ten seconds, until the Apple logo appears.
Clean the screen with a soft, slightly damp, lint-free cloth.
Avoid using the device while wearing gloves, with wet hands, or immediately after applying hand lotion.
If you have a protective case, or if you are using a plastic sheet or film on the display, try removing them and testing the device without it.
If that does not resolve the issue, I would next quit all the running apps on the device:
iOS: Force an app to close
Double-click the Home button.
Swipe left or right until you have located the app you wish to close.
Swipe the app up to close it.
When you have done that restart the device and test the issue again:
iOS: Turning off and on (restarting) and resetting
Thank you for using Apple Support Communities.
All the very best,
Sterling

I accidently deleted my pre-installed safari program on my iphone and can't find it anywhere. I have tried to search spots to download it again, but not sure which is the right download as only see for mac users etc. Need help to get safari back Iphone 4

Hi,
I have accidently deleted safari from my iphone and can't find it to put it back. I did it ages ago as I didn't know what it was and I was trying to create extra space! Now when I click on a link say in an email, it doesn't come up with a browser. I have looked at the apple site but can only see a download for mac users. Not sure if this is the case because it is preinstalled on the iphone.
Help needed please!
Linda/Phillip

Try this...
Reset your Home screen to the default layout:
Choose Settings > General > Reset and tap Reset Home Screen Layout.

I can't connect to wifi network and bluetooth on iPhone 4S. Need help. Have already rebooted everything and reset network setting

I can't connect to wifi network and bluetooth on iPhone 4S. Need help. Have already rebooted everything and reset network setting

I have the same problem; tried a phone restore, both restoring data and setting up as new phone with factory settings, reset all settings, re-boot, remove apostrophe, put in fridge, you name it!
I think there's quite a few iphone 4s users with the same problem!
I called Apple they said it's a hardware problem, but it has worked for nearly two years; they say go to the Apple store and they can provide a replacement phone for approx. £150!
I've been into the O2 shop where I bought it and they knew the problem exactly; said they had sent a few phones off for repair and had them back awith a report they cannot fix it because it's a software problem!
An assistant in the shop had the same issues; logic says it's a software problem and hopefully Apple will fix it with a patch but at the moment they seem to be avoiding everyones comments!
If anyone else has any ideas these would be appreciated?

Thanks.

Here, let me explain the way you use the word "crap" in a sentence like this, especially when I'm asking for help from a total stranger such as yourself. It's rude, obviously I know now not to do something like download something like that to my computer. It's not the difficult to figure out, and obviously I'm suffering the consequences for it now. So are you planning on helping me? Or should I not reply to your next reply if it has the word "crap" in it? I'm sure this whole discussion board was created to be used in a professional way, which is how I would like to keep my responses.

My iPhone 4 can not find network after updating to 7.0.6

The Bluetooth low energy protocol is not backward compatible with classic Bluetooth protocol. My iPhone 4s can not find my sonny in-dash player. However my iPhone 3GS does it. Very disappointed with this. Any idea how it can be fixed???

Hello,
You are correct, Blue tooth low engergy, BTLE.(only) devices are not backward compatible with Classic bluetooth and cannot connect.
However the Apple 4S and above have Bluetooth 4.0 support.. Hardware wise it has bothClassic Bluetooth, like the 3GS, as well as Bluetooth Low Energy. There is no good reason why your 4s cannot communicate to your Sony in-dash player using the Classic bluetooth that resides in the 4S.
I know that this does not answer the why it does not work, but it should work. Do you have to somehow re-pair the new phone up to the player? Not knowing the model of the Sony it is hard to investigate.
And I hate to ask but are you sure that the Bluetooth radio is on in the phone?

HT4061 i lost my iphone how can i find it through find my iphone

i lost my iphone how can i find it through find my iphone

Well, Firstly, It Is Only Possible to find it using 'Find my iPhone' If location services are turned on on the device.
you can track it using a computer or any iDevice.
if you have a computer, login to www.icloud.com using yor iCloid credentials and click on Find My iPhone. You can track the device, provided location services are turned on and it is connected to the internet.
if you have any iDevice, login to the 'Find My iPhone' App[Download it from app store for free if it isnt there already] and do the same.
All the best

There is an app I want to purchase for my iphone , but can't find it on the app store from my MacBook Pro

There is an app I want to purchase for my iphone , but can't find it on the app store from my MacBook Pro. I have credit on the Mac Book, but can't see it from iphone.

Are you checking from within the Apps section of iTunes on your computer? Is there a reason you can't download it directly to the iPhone?

I misplaced my iphone. i cant find it. i downloaded find my iphone but i can't add my device (my lost iPhone) how can i find it since it is on silence. is there a way i can add this device from my macbook?

You have to have enabled Find My iPhone on your phone before it was lost in order for it to be located. If you did, you could play a loud two minute sound on it even if it was on slient, as explained here: http://help.apple.com/icloud/#/mmfc0f19b5.

AirPrint - iPhone 5 can not find printer after router change

AirPrint - iPhone 5 can not find printer after router change; however router is exact replacement of previous one (Zyxel, issued by Imagine wireless). AirPrint was working previously.

IPhone 4s can't find cellular network. iPad logged right on. Tried soft reset and two button reset, neither worked. In Detroit airport any ideas?

Iphone 4s can't find cellular network in Detroit airport. iPad logged right on. Tried reset network and hard boot and airplane off on. No luck. Any ideas?

So, I can see that nobody had any ideas. In case anyone is interested, I did cave and get an Airport Extreme. My iPhone 4s connected in about 3 seconds, as did my MacBook, my iMac and my old 3G phone. The router is in the EXACT SAME SPOT as my Netgear router. No reception problems, no dropping wifi.
The Sony Blu-Ray connected on the second attempt, but the TiVos are another story. Reset my N-adapters to factory default and then did setup, found the network just fine assured me that my wifi was configured to the new router, but the TiVos refuse to connect. It's always something! lol I'm sure somebody can tell me how to fix this.
