TS1398 iPhone 4 IOS 5.1.1 can no longer connect to my home wifi.

I upgraded my IOS using the latest version of iTunes on my Win 7 PC. Now, I'm unable to connect to my AT&T U-Verse wifi. When I try, I get the message "Unable to join network". I tried restarting the iPhone. I tried restarting my wireless router. I tried resetting my network settings on my iPhone. Help...

I've tried the following:
* Settings | General | Reset | Reset Network Settings (Twice)
* Settings | General | Reset | Reset All Settings (Once)
* Plugging it in and doing a "Restore" through iTunes (that's how I downloaded iOS 5.1.1 in the first place)
All the passcodes and restrictions are are turned off.
When I first try to connect to the network, I'm prompted to enter my username and password (I've elected to "forget" the network a few times so I can get this screen again). If I enter it wrong, then I just get an error that I'm not connected. When I enter it right, I get a warning that the certificate is "not verified". When I click on "More Details", I can see all the information that got pulled from the network (Issuer Name, Signature Algorithm, Public Key Algorithm, Key Usage, etc.). When I choose to "Accept", I get the little icon indicating that it's trying to connect...this never goes away (I let it run for an hour).
The encryption type on the main Wifi I'm trying to connect to says it's RSA (I'm guessing it's WEP though...I didn't set it up, our IT group did that).

Downloaded iOS 5.1 and can no longer connect to any encrypted Wifi?

I just downloaded the latest iOS and did a full factory reset on my iTouch in hopes of getting it ready to go to a co-worker. I've been test-driving the device to see if we wanted to use Apple vs Android products for the applications we're developing for our research facility. Things were going fairly smoothly until I did this. Now, I no longer have access to any encrypted network (I have access to 2), which essentially has given me a nice paperweight I can give to my co-worker (we deal with HIPAA information that has to be encrypted). It does have access to guest networks, so I know it's a software problem (not a hardware problem). I tried calling Apple, but we're outside our 90-day limit. I thought they were known for their excellent support, but if I have to pay for fixing something their update broke (sounds like a great way to make money if you ask me), I won't be recommending it for our software development.
Anyone aware of any settings I need to dig-into to get this to work? (I feel like my hands are tied because I can't poke around in any of the directories to browse through files and settings; something I'm not afraid to do as a software developer.)

TS1398 After updating to ios 6 my iphone 4 would no longer connect to my home wifi. At work we have a free wifi connection that does not require a password. However my wifi at home is password protected. I have the right password. It works on my ipod touc

After updating my iphone 4 with the ios 6 update. My iphone would no longer connect to my home wifi that is password protected. I know that I have the right password entered in. At work we have a free wifi connection that does not require a password and I can connect no problem to it. My ipod touch has no problem connecting to my home wifi. It is a 3rd gen ipod and does not have the ios 6 update on it. Please help!

I'm having the same issues. Started when I upgraded iphone 4S and ipad1 to 5.1.1. Wife's iphone 4g on 4.4.2 has been ok. I've forgot the network on both devices and restored the iphone, none of which changed the issue. I've upgraded to ios 6 on the iphone 4s, problem still persists.
One thing that will help for a time: go to your router and change the wireless control channel. When I first did this I got full connectivity for about 48 hours... and now the problem is back. I'm now changing the wireless control channel every 12 hours, which is a pain but at least keeps me connected. I've tried a few other solutions that are out there and that has been the best one so far.
to do this on a motorola router: type 192.168.0.1 in your address bar.
username: admin and password:motorola if you have not changed the factory defaults.
Click on the word "wireless" and look for the "control channel" field. This may be set to auto or to 1, try changing it to 6 or 11 (preferred) or any other channel.
The control channel can cause static in the wireless system IF there are several networks nearby that are on the default setup.
There is a fair bit of buzz about this issue out there, some other things I've seen:
This is a hardware issue. Go to the store and have your wifi antenna checked, some users reporting that they get free replacement devices.
Check against other wifi networks that require a password (this is next for me). Logon to those networks and surf until your wifi stops. If your wifi connects to the internet but stops responding, then this is a software (or hardware) issue and apple needs to step up. Some are claiming this to be the case.
IF you connect and stay connected/on the internet on another password protected wifi, then the issue is with your router. this is where things get cute.
Comcast may tell you to update your firmware. Motorola may tell you that your cable provider is the only one who can push through firmware updates. Comcast may tell you that you are not in an area that is being updated. It's unclear if they say that to all customers, or just those who have purchased cable modems and aren't renting them from comcast.
Good luck, more to come if I figure out anything else, and please post any solutions you may find.

my iphone will no longer connect to my home wifi. it recognises it, but the searching cirlce is constant next to network name. there are three laptops and another iphone on the same wifi that have no connectivity issues. i have reset the network settings but that did not help. the issue started last week when the second iphone was introduced to the house, could this be the cause?

No.
Any problem connecting your iPhone to any other wi-fi network besides your own?

Updated to iOS 7.1.2 - Can no longer connect to WiFi

There is clearly a bug introduced after updating to iOS 7.1.2 and I inadvertently repeated this mistake on two iPhones (5 and 4S).
Immediately after updating to the latest iOS, I was experiencing sporadic WiFi drop outs, especially for short time immediately after taking the phone out of standby.
Then I attempted someone's 'brilliant' suggestion of selecting "Forget Network" and then adding it back in. THAT was a huge mistake because after doing that and reconnecting to my WiFi network, everything seemed fine until I woke the phone (iPhone 5) from its next standby. Since then, I can no longer connect to my WiFi network. In fact, no WiFi networks in my vicinity appear! In order words, I am now completely reliant on my limited data plan!
To make matters worse, because of this screw up, my cell data plan exceeded my 3 GB usage and I had to pay $60 in overage for July! I am not happy!
This is made even more outrageous considering that Apple hasn't acknowledge this issue!
BTW, I have tried and wasted a LOT of time trying each of these so-called Apple remedies:
Blog entry titled, "
How to fix Wi-Fi issues on your iPhone or iPad after updating to iOS 7.1.2"

There is no need for Apple to acknowledge anything, because it is not a bug.
Yeah, I've seen the play out before with past iOS updates (re: unresponsive slide to unlock/cannot answer calls). Thousands of people complain but the AFB's jump all over them by calling them newbs or worse. Then Apple releases a patch and the problems quietly disappear. It is kind of annoying to see this replay! Please don't be so sure that it isn't a bug. The fact is, Apple made patches and despite the homogeneous nature of iPhones, there are still literally millions of possible ways that iOS patches can affect some phones but not all phones. You cannot claim unequivocally, that this is NOT a bug.
So you are suggesting that all the complaints about this issue are imaginary?
As it relates to my situation, I have two iPods, one iPad, two iPhones, a desktop, and an Android tablet.... only the two iPhones lose the WiFi connection (during standby) and these devices were both updated to iOS 7.1.2.
Solution: It's the WiFi on my router that is at fault?
AmishCake wrote:
Millions of people are NOT experiencing this issue. Have you tried rebooting your router by unplugging it for 30-60 seconds?
I never made any claim as to the number of people affected. Besides, even if only 50 people posted messages to this forum, the number of people who do not participate in the Apple forum far outnumber the people who do.
With all due respect, I appreciate your attempt to help. In fact, to humor you... I will power off my router, just like you describe (can't hurt... it hasn't been powered down in about a year now).
I'll reply back with a "thank you", if your suggestion worked.

IOS 8.1.1 can no longer connect to corporate wifi

After updating a couple of corporate iPhone 5s' they now no longer connect to the corporate wifi. This happens whether updating OTA or a complete wipe and reload in iTunes. Wifi worked fine before the 8.1.1 update

We have 2 separate discussions going on here. You jumped into a thread about a problem connecting to a corporate WiFi network with a post about a different WiFi problem. You have been answering questions asked of the original poster, which kind of confuses the issue. Look at who a post is in response to before answering.
For your problem, does the phone fail to connect to all WiFi networks, or only one (e.g., your home network)? Do you see WiFi networks when you tap Settings/WiFi?

IPod 4th Gen will no longer connect to my home wifi, what can I do?

This problem started recently, I would arrive home, take my iPod off airplane mode (and yes, wifi did turn on) but my iPod would just not connect to my home wifi. I went to wifi>choose a network and manually selected my network but when I did, it would say "Unable to joine the network 'network name'". This problem slowly got worse: when I would wake up in the mornings or after not using my iPod for a long period of time, the same issue would occur! Usually it would take at least an hour if i was lucky of consatant retrying before, miraculously, it would connect. That was, up until yesterday though, when it would just simply not connect and display the message. I have tried almost everything I could think of: forgetting the network, restarting the iPod, restarting the modem/router (its an all in one setup), and even resetting the iPod but it just won't work, so now i'm stuck with a wiped iPod that just won't connect. One last thing, all my other wireless devices (iPad, PS3, laptop) work just fine and my iPod can connect to other networks. Please help me as I use my iPod very frequently and can't even restore to iCloud back-up.

Does the iOS device connect to other networks?
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

TS1398 I can no longer connect to my home wireless on my ipad2, have done all the suggested fixes, still cannot connect. Daughter cannot connect her iPod, but husbands laptop is connected to wireless.

All of a sudden my ipad will not connect to our home wireless. I have reset the wireless settings, turned my ipad off and back on, turned off wireless and back on, basically have done all of the fixes suggested and still I cannot connect. My daughter cannot connect her iPod either, but my husbands laptop can and is connected to our wireless. The wireless is working and until two days ago I had no problems connecting.

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Why can I no longer connect to my home WIFI

Hi All
This is my first post and I know from searching online for the last week or so for a solution that this has been a problem for others before. I have tried all of the proposed solutions I have found including, resetting the network settings, resetting all settings, turning the wifi on and off, manually enterring information used within another phone on the manual element of the wifi setup.
I still cannot connect my phone to my home WIFI despite it being conencted for over a year with no problems, and also having other iphones, laptops and Ipads that can connect.
The phone that wont connect can still pick up other WIFI networks and barely finds my home WIFI.
I would really appreciate some help with this as we rely on the WIFI due to not picking up great 3G in my area.
Thanks in advance.
Mark

I have had the same issue many times with Apple products (Mac, Macbook Pro, IPad) when I have been travelling (hotel, restaurant, coffee shop etc. wifi) or using an "off-site" wifi system. The solutions seems to be to unplug your router from the wall and wait about 10-seconds than plug the unit back in. Works everytime for me.

Why can't I connect to my home WiFi after the 8.3 update?

I have updated my iPhone 6 to the latest iOS 8.3 and now I cannot connect to my WiFi at home, why? I've done a clean install and rebooted my home router and still no connection. However the device does connect to my workplace WiFi. All my other devices are connecting to home router as well.

Do you get an error message?
Reboot your router again, but this time do it by removing all power for about 30 seconds.
If it still doesn't connect and doesn't display an error, wait 1 minute after selecting the SSID on the phone, then go to Settings/WiFi and tap on the i next to the SSID. Look at the IP address. If it begins 169.254 then it's a router problem; the router has failed to assign an IP address to the phone within 30 seconds of a request from the phone. The phone then self-assigned an ad hoc IP address.

Why can't I connect to my Home wifi?

I have one everything I can think if but my ipad mini will not connect to my home wifi

Have you worked through http://support.apple.com/kb/TS1398 and if the WiFi is greyed out, http://support.apple.com/kb/TS1559 and have you tried a full restart of the router by shutting down, wait about 10 minutes and then restart it, restarting other equipment one piece at a time waiting a few minutes for each to capture a new IP address.

HT1695 i downloaded the IOS software upgrade and can no longer connect to any WiFi network, what can I do to fix this?

I have attempted to reset the network settings, nothing changed. The wireless router is working and has nothing wrong with it. Ever since I downloaded the software update, WiFi connection can not happen and every time I try to do anything that uses the internet it directs me to the apple support site. How can this be resolved?

I've tried the following:
* Settings | General | Reset | Reset Network Settings (Twice)
* Settings | General | Reset | Reset All Settings (Once)
* Plugging it in and doing a "Restore" through iTunes (that's how I downloaded iOS 5.1.1 in the first place)
All the passcodes and restrictions are are turned off.
When I first try to connect to the network, I'm prompted to enter my username and password (I've elected to "forget" the network a few times so I can get this screen again). If I enter it wrong, then I just get an error that I'm not connected. When I enter it right, I get a warning that the certificate is "not verified". When I click on "More Details", I can see all the information that got pulled from the network (Issuer Name, Signature Algorithm, Public Key Algorithm, Key Usage, etc.). When I choose to "Accept", I get the little icon indicating that it's trying to connect...this never goes away (I let it run for an hour).
The encryption type on the main Wifi I'm trying to connect to says it's RSA (I'm guessing it's WEP though...I didn't set it up, our IT group did that).
