HT4972 I cannot connect to wifi since upgrading to ios 5.1

Since upgrading to iOS 5.1.1 I cannot connect to wifi. I damaged my last phone so Apple replaced it with my current phone but since I've had it it won't connect. The 'choose a Network' message just has a whirly circle like it trying to connect. I've tried resetting my phone and resetting my router but it doesn't work. Can anyone help? I'm now getting a message saying I need to back up to iCloud but I can't do this without connecting to wifi.

Thanks but this has not helped. I've booked an appointment at the Apple store on Snday. Helpfully they will be able to fix it without charging me alive only had this phone since May this year.

MY iphone 4s cannot connect to wifi after updating to ios 8.1.1

after updating to ios 8.1.1, my iphone 4s cannot connect to wifi at all.

No connection to Wifi after upgrade to iOS 7.1 AND poor battery life

Hi,
after upgrading my iPhone 4s to iOS to 7.1, I cannot connect to any Wifi anymore. Does anybody have an idea how to solve this issue?
Additional, I am wondering why battery life is much worse after the upgrade. I closed all apps via multitasking view. Nevertheless, battery is empty within a couple of hours. (before the upgrade, it lasted approx one day!!!)
Any help is highly appreciated!
Thanks!

After every iOS update there are reports of users experiencing faster than normal battery drain. Most find that basic troubleshooting from the User's Guide resolves the issue.
Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).
I am not having issues with battery drain on my device, it was at 50% around 2PM today, removed off the charger at 6:30AM and I'm a fairly heavy user of the device.

Not sure what you mean that you have no signal but are on 3. What are you trying to say?

Cannot connect to wifi since signing in to drop box sincce long

unable to get wifi to work after trying everything.

Also correct what you wrote but I have had so many issues ,with my more than fast reliable with the highest specs MBP, got that firesoved with great help from Apple support, than Ableton (music production program started to play up for no reason at all, so Ableton support solved about 80 % of it, lost all my pass words on my non jailbroken iPhone 5s that can not be restored via iCloud, for that you need yosemity. My work passion and to keep sane is producing music, Ableton is not ready for yosemity therefor I stick with Mountain Lion (I am also a manager of a big shop :-( ) I password gave my as the only solution first to sync with dropbox via drop box to iPhone. Not big fan of drop box and as I know that Drop Bopx can take and use quite a bit of tour broadband (i wish, I am in Thailand) but wifi so all this stuff first with my Mac, Ableton 1 Password, Dropbox, I always triy do resolve it my self witch at least takes me a day or longer. So loosing my wifi my tired but simple way of thinking is Drop Box is using all the wifi in the background.
Just to make things a little more clear. Just lost my patience completely, 10 hours behind the comp 5 hours sleep , does nobody any good.
Anyway.
All is good and sorry again

Cannot connect to server since upgrade to 31.6. Cannot create a new account either.

Tried to change port settings, but that did not work. Chatted with comcast, but they couldn't fix the problem. Made it worse by suggesting that I delete old account and reestablish a new one. Deleting old account made it worse by removing my large inbox. New account message from Thunderbird is that it "failed to find the settings for your email account." In addition, the error console has this message "Timestamp: 4/6/2015 11:51:08 AM
Warning: mutating the [[Prototype]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[Prototype]] value using Object.create
Source File: resource://gre/components/steelApplication.js
Line: 783"
Tries to reestablish using POP instead of changing to IMAP. Same message. see image

First of all get the correct server settings from Comcast.
If Thunderbird fails to detect the correct settings automatically follow these instructions.

Can't connect to WIFI after upgrading to IOS 6

After upgrading to IOS6, my 4S stopped connecting any available wifi networks. It keep poping up "Unable to join the network "***" " when I tap any wifi spots I've been used so far. My problem is not like most people says. Instead of taking me the the apple website, mine doesn't even connected! This problem has been around for a week. I have to relay on 3G so far. I've tried resting the wifi setting, resting the iphone and even tried a lot of public wifi spots. It still doesn't work. Is it the problem of hardware? Help me, plz!

The solution lies in the router password encryption. There is the option WPA2 instead of current WPA/WPA2 on my router. I changed the setting to just WPA2 and it worked now. But the former option worked on iOS5.1.1. Thanks!
[Update]Turns out it is still unresolved. After the changing the encryption I restarted the router and it is still the luck I got before. The connection will not last long. Still unable to connect.

Some iPhones cannot download our podcast since upgrading to IOS.5?

Our podcast can be downloaded fine on iTune sand on most mobile devices, but some people say it stops downloading after 15.6kb. Why would this be, they have said it has happened since they upgraded to the IOS.5?

Hi, I found your question whilst trying to work out why my podcasts were doing this. Thought I'd update with my solution in case it's of help to you.
I found the solution by trial and error in the end. I moved the mp3 files onto another hosting space that we had to see if that helped, and it fixed it.
I can only assume that because the files were uploaded into our CMS originally, something weird was happening on ios devices to stop it downloading.
Might be worth moving your files just to see? I found your site (saw a similar question you posted with the feed in another bit of this site) and I noticed it's made with Drupal. I don't know Drupal myself but I'm guessing if you have uploaded the mp3 files as assets in the CMS, it might be the cause of the problem?
Cheers

Anyone still having issues with connecting to wifi since updating to IOS 6.1.1 (iPhone 4S)?

It worked for about 5 mins every 40 mins up until 12 hours after updating the software. The wifi is greyed out (can't turn on or off) now, and I am becoming rather frustrated with this as I have been without internet for at least a week now, with my work relying heavily upon internet access. Any help would be great, I have done the hard reset, a normal shut-down, and I have restored my iPhone twice now and still no change. ANY help would be fantastic!

I'm having the exact same problem! However, mine hasn't worked at all even after resetting network settings, restoring phone from back up and as a new iPhone, drained the battery and turned the phone on and off. I am really angry because apple released an update yesterday to fix bugs specifically on iPhone 4S and it has done nothing. My idea would be to book an appointment with your local apple store. I have one on Saturday and hopefully they will replace the phone as I am still under warranty. If you're not still under warranty I think it'll cost you some money, which ***** because its apples fault.

Cannot play video on ipad 2 since upgrade to ios 6

Cannot play any video since upgrade to ios 6 on ipad 2! Anyone else having this problem?

Yes! Immediately after upgrading our iPhones and iPads to iOS6, they lost the capability to play back CCTV camera streams both on network and 3/4G. Our customers are experiening this issue as well.
I held back from upgrading one of my iPads and all is normal with it.
I am a Savant AV dealer and this is quite troubling especially since the issue has very little buzz.
Has anyone heard from Apple regarding a fix?
Thanks,
Phil

TS1398 my iPad will not connect to wifi since the ios7 upgrade

Since updading my iPad to iOS7 I cannot connect to WIFI. I have put the device in airplane mode, reset newtork settings per other suggestions but it didn't work. I have powered the device off and on. I have reset home router. iPhone 5 still works as I refuse to upgrade to iOS7 for now.
Finally got it working. Continued following the above steps and it worked. I've tried this at least a dozen times with no success but all of a sudden it worked. I hope it continues to work.

Try a soft reset or turn the device completely off then turn it back on again. Also you can toggle Airplane mode on for about 10 seconds and then turn it off. Sometimes that resets the radio signal inside the device.
A soft reset is basically holding onto the power button and the home button simultaneously together for about 10 seconds or until you see the screen flash and it should go completely black. Afterwards, tun the device back on like normally and see if that fixes the problem.

If these don't work you may have a hardware problem. Visit an Apple store for an evaluation or contact Apple Support.

Upgraded to Maverick. Now cannot connect to wifi. All my other devices will connect. Have rest wireless hot spot switch and cable modem. Other devices still connect but MacPro does not. MacPro wireless is self assigning an IP address blocking access.

MacPro wireless is self assigning an IP address blocking access. It will connect if I connect to my iPhone hot spot via wifi. Any ideas?

If you follow this video you'll see how to delete your WiFi AP from the OS, this will allow you to select it again which I feel will correct your problem.

Since upgrading to IOS 8.0.2 I can't connect to wifi

Since upgrading to IOS 8.0.2 last week I'm unable to connect to anyones wifi.
I've cleared the network settings, updated the carrier settings and restored it as a new phone and nothing works.........
PLEASE HELP ME

I have been to the Apple store twice about this problem I have with my iPad. Wifi does connect to non-password or authentication wifi. In my humble opinion, I believe the problem is no hardware or wifi, it may be related to keyboard languages or a keyboard recognition bug in the update. My iPad recognizes the correct number of characters to allow me to click the join button, but that is where I get my password incorrect, or can't connect message. I have 1 language and emoji which now has no ability to remove. Maybe it is defaulting to emoji?
