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?

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).

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"

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?

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.

I just upgraded to Yosemite and can no longer connect to the WIFI any suggestions

I Just up upgraded to Yosemite and can no longer connect to internet - any ideas?

I have the same problem after loading OS X 10.10 Yosemite on my MacBook Pro (Late 2008). Wi-Fi (Time Capsule) connects OK, then I open Safari and it waits for a minute and then gives me a message that it can't load the page because I'm not connected to the Internet. The Wi-Fi is fine. When I run the network analysis, it shows that everything is fine up to the Internet; the dots are red after that. I have another MacBook Pro (Retina, Mid 2012) and it loaded and runs with no known problems (so far). I am writing this message on the Late 2008 MacBook Pro, so you can see that there is no problem with the Internet connection. It is a Yosemite problem. My iPhone and newer MacBook Pro connect with no problem. I loaded Yosemite TWICE, then ran the Disk Utility and fixed some disk permissions but there were no other problems identified. Restarting after reloading Yosemite and the same problem is there. Restarted after running the disk utility and fixing disk permissions and it still can't connect to the Internet. Same problem. Does anyone have an idea how this might be fixed? What's going on? Thanks for your help.
Update: Air Drop also doesn't work. Thanks.

XP can no longer connect to corporate VPN

Since I replaced my Linksys router with the AirPort Extreme, I can no longer negotiate a VPN connection with the corporate network. After password verification, the error I receive is "Unable to establish connection to server to validate security files."
The corporate Help desk tells me that "the most common problem with PPTP is negotiating a connection on TCP port 1723 and being able to send and receive data from the PPTP server using the GRE protocol (IP Protocol 47, 0x2F in Network Monitor)." I've opened port 1723 in AirPort Utility, but there's no change.
Is there some other adjustment I can make to the AirPort Extreme's settings? Do I need to enable GRE somehow? (I don't remember any special adjustments to the Linksys's settings.)
Thanks for any help you network experts can offer.

Have you tried making this computer DMZ? Probably already have but just makin sure

After I updated my iphone 4 to the iOS 5.1.1, I cant longer connect to any wifi/internet.

After I updated my loved iphone 4 to the iOS 5.1.1, I cant longer find any internet at the wifi? I know there is a internet connection here, im at that network on my computer, so yeah... it always worked before, until i updated. WHAT TO DO?!
i have reset all the settings, and now im trying to reset the whole iphone.. heelp

This happened to me the same day that ios 5.1.1 came out. I went to iTunes to sync my iPhone, as I normally do. I declined the 5.1.1 upgrade. Shortly after syncing, my phone started acting slow and went to the black screen where the Apple logo usually pops up.
I turned my iPhone on and off. Then, when I tried to connect to the internet, I was told that i had no connection. I went into the wifi screen and it would appear to look for a signal, but never could find any wifi network whatsoever.
I turned my iPhone on and off again. When I went into Settings, the Wi-Fi option was now grayed out and the message where the wifi network name would normally appear showed "No Wi-Fi.'
I restored every possible way. I called Apple Care and they told me to do the same restore which I already did.
Since that didn't help, I went into the Apple store and they looked at the phone, said it was a hardware issue and gave me a "new" phone.
I really don't think it was a hardware issue, as I only had my phone since February and the wifi always worked fine. It's too much of a coincidence that the wifi was working just fine right before the sync but failed right after th sync.
What I do believe might be related to the issue is: prior to the ios 5.1.1 update, there was also a Carrier Update which I declined. I believe that Carrier Update had to do with adding new Hotspot features. That option was never on my phone before, but it appeared in the General -> Network tab after I synced that day. I think iTunes somehow automatically did the Carrier Update and that somehow screwed up the wi-fi option in combination with other unknown factors. My phone is also unlocked from Apple, if that has anything to do with it.

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.)

Phone will no longer connect to home wifi.

My phone just sits there loading on the the Belkin router option that is my home wifi. I've tried resetting my phone and syncing to itunes and nothing seems to work. I've also tried forgetting the network, then reentering the wifi code; this also doesn't work. I have a limited data plan so I need this wifi to keep from going over that 2 GB limit as the overdraft fees will wreck me.

I can only choose hotspot browser as my default browser, I have no other option available.
I am on an orange 12 month canary plan.
Please help me connect to wifi!
I forget which Orange UK plan I'm on, but it works fine so
Does you plan include Data?
Which carrier's SIm were you using before? Have they turned off your service yet?
Have Orange enabled your BIS (data plan needed)
If you do not have a data plan, why not? (not meant to offend - but need to know to assist)

Who can shed some light on my ongoing connection problem.
After upgrading my iPad Air with IOS 7.06, I could no longer connect to the internet.
I have 2 MacBooks Air, 1 ipad mini and one iPhone 4S running on the same network, and they are all connected to the net and function well.
So I cleaned up the ipad completely, installed the latest firmware and reinstalled my apps : no connection.
I tried all things of resets and forgets. No result.
I have been fondling with my Airport Extreme 5 , but that did not help much.
This morning I went to a neighbor , hooked my ipad air on his network, typed the password and the thing all worked fine.
I have tried to connect the ipad air as an ethernet client, but that did not work. „Not enough power“ was the statement
Ideas anyone ?

Yes I tried this manyfold. But did not work. Reading on, I took Tesserac's advice. Shut down router and computer.
Start router after 15 minutes and wait another 10 minutes before starting the computer.
Et voila.... everything is back in working order,

After I updated my iphone 4 to ios 6.1.3 I can no longer connect to my bluetooth, plantronics model M25. I tried reset all settings after turning on and off also submitted diagnostic. Do I have to buy yet another bluetooth set?

Thank you wjsten for your soon reply. Unfortunately on these days I'm in a country that Apple don't have any retail store here and for sake of time I prefer to fix it myself to DHL it to the nearest country to use its warranty. Do you have any idea how can I fix it? Do you think it's a software issue?

Can no longer connect iPad Mini 2 to iPhone 6 Personal Hotspot (iOS 8.1.2 on both)

I can no longer connect my iPad Mini 2 w/ iOS 8.1.2 to connect to my iPhone 6 (iOS 8.1.2, Verizon Wireless) running Personal Hotspot.The iPad displays the error "Remote Hotspot Failure - Unable to start personal hotspot "iPhone. However, my Windows 8.1 laptop connects to the iPhone just fine. The iPad connection problem occurs with or without the Windows laptop connected or even turned on.
Both the iPhone and iPad have Bluetooth and WiFi on, and the iPhone has Hotspot active. The iPad shows the iPhone Personal Hotspot on the WiFi Settings page, but throws the error each time i attempt to connect. Additionally, the iPhone shows 1 Connection on Personal Hotspot even though I have no devices connected. I have reset my network settings twice on both the iPhone and iPad.
BTW - I used to be able to connect the iPad to the Hotspot prior to updating to iOS 8.1.2 on both devices.

Forgetting the hotspot on the iPad sent me in the right direction. I now have it working correctly, and seem to have diagnosed the cause.
The cause seems to be that I had connected the iPad to the Hotspot via Bluetooth. Once I figured out how to delete that link, I was finally able to connect to the Hotspot. Here is what I had to do:
On the iPhone:
- Turn on WiFi and Bluetooth
- Turn on Personal Hotspot and change the Hotspot password (this may not have been necessary, but things are now working)
On the iPad:
Reset all network settings:
Settings -> General -> Reset (at bottom of page) -> Reset Network Settings (deletes all known networks and their passwords and restarts the iPad)
Turn on WiFi and Bluetooth (I had found that Bluetooth must be on is necessary in some other research)
DO NOT CONNECT TO THE PERSONAL HOTSPOT USING BLUETOOTH - DON'T GO THERE!
Connect to the Hotspot using WiFi
Settings ->WiFi
- Wait until you see "iPhone" under PERSONAL HOTSPOTS (or maybe CHOOSE A NETWORK)
- Select "iPhone"
- Enter the (new) password that you set on for the PERSONAL HOTSPOT on the iPhone
You should now be connected via WiFi
Bottom line: Unless you have some VERY compelling reason to connect to the Hotspot via Bluetooth, NEVER do it. WiFi speed is multiples that of Bluetooth. With WiFi using Broadband Speedtest over Verizon LTE - 2 bars/dots - I am consistently getting between 15 and 20 Mb download and 3-15 Mb upload. With Bluteooth using the same test, I was getting about 1 Mb maximum upload and download.
I hope this solves the problem for all reading this thread. And thank you ManSinha for the helpful clue.
