iOS 7.1.1 update causing wifi problems

I am also having issues with my iPhone 4 since the 7.1.1 update. (Lastnight April 29th)

My wifi will not connect and states the wireless password is incorrect.

(Yes, I checked the password and entered it in while I was looking at the Network Settings page on my router)

It didn't remeber the network either and will not let me renew the lease.

Any advice Apple???

Perhaps a new update coming soon?

If not, can I revert back to a previous update?

Well, the Almond worked, which pretty well seals the deal for me that my problems are linked to the 7.1.1 push. Apple fail.

I'm having the same issue with my iPad 2. All other devices like iPhone, iPod and the other iPad have no problem connecting to WiFi. It's only the ios 7.1.1 iPad 2 which keep loosing network connection. Also the connection strenght is lower then before and lower compaired to the other ios devices.

My wifi no longer works on iPad3 after the 7.1.1 update. Was working before update. Network reset did not help. Go figure that major functionality of the device would be adversely targeted by an Apple software update. Makes one wonder about the intent and competency of these updates.

Same issue on 2 devices after 7.1.1 update other devices not updated are fine.

Issue every few minutes ios 7.1.1 device drops wifi have to go back and reconnect via settings.

Issue occurs on home and work networks and started 30mins after update.

Restore / factory reset did not make a difference.

I am having an issue with this also.

After 7.1.1, my wifi disconnects but specifically when I'm downloading from itunes and usually a larger file I.e. A movie.

Some app updates also do this.

I am on BT Infinity 2 with unlimited downloads.

My wifi/internet works fine everything else including Netflix, apply TV so this is purely down to this update.

I updated my iPhone 5 and my iPad 3 to 7.1.1, but I did not update my iPad Mini Retina.

The 5 and the big iPad now load pages in Safari painfully slowly. The Mini is still darting from page to page like a happy squirrel.

Coincidence? I think not.

Here's hoping for another patch soon.

Same issue on my ipad 2. I was using the internet fine, did the update then my connectivity was dramatically reduced and the wifi signal keeps dropping. However the whole time my son has been watching Netflix on his TV with no interruptions and my PC still connects fine. DEFINITLEY AN UPDATE ISSUE. I desperately need a fix.

Thank God I'm not losing my mind :-) I thought my iphone 5 was possessed - I updated last night - same thing was happing - similar stuff happening.

I had 3 different work emails on my phone (all with same domain) - but my main email account kept saying my incoming mail server not responding or can't verify - then that would fix it self - and then it wouldn't retrieve any of my emails at all - yet my ipad with the exact same settings would retrieve my emails.

So I deleted the whole account reset it up using same network and same server settings - it would do a complete dump of 100 emails - but then i would start getting the same message again. I even tried a restore from as far back as February - iphone would work for a few minutes but then it kept dropping my network server details - both in receiving and sending.

There's no logic to the sequencing *shaking head*

I can't get that far

From settings > wifi > no more optiona available

Wifi not available is my message from control center

We had a similar problem on just the home network, on other networks we could still connect. I went into the modem'a asdministration and reset the pre-shared key for the network and reset Network Connections and when I put in the network's new password I had no further problems.

I'm having some what similar issues, since updating to 7.1.1. The slow connection is across all forms of data transfer. My wifi and my LTE are both running very slow, since updating. Simple things like browsing Facebook or watching videos on YouTube now take twice as long to accomplish.

Everything was working just fine, before the update.

It should also be noted that my battery drains at a completely unacceptable rate now. I never have bluetooth or anything like that on and I rarely even use it while at work, but for the occasional text.

I got to work 6 hours ago and my battery was 100%. It is now at 17% and it has been just sitting idly on my desk for the majority of the day.

I'm having the same problem. I don't understand my ipad is working fine but my phone is dropping internet every like 2 minutes. I hope apple fixes this problem

Resetting the "Network Settings" seem to have worked so far for me.

Same problem with iPhone 5 since updating to iOS 7.1.1.

So far I have tried:

1) resetting network setting

2) restoring to factory settings to a new as well as to a backed-up setting

3) restarting wifi router.

4) using different wifi networks

What baffles me about this wifi problem is that despite pretty consistent and in apparantly unchanged signal strength, the actual measured speed/performance of the wifi has dropped significantly.

In order to ascertain what exactly is going on with the wifi, I ran a speed test on the wifi from different locations throughout my office. Near the router it still seems to work as well as before. Step a few feet away from the router and the wifi's speed seems to drop rapidly despite fairly consistent signal strenght (3 bars throughout). In actual numbers, my work's wifi used to have download speeds at about 11 to 13 kbps with a(n expected) neglible to moderate drop throughout the space away from the router. In earlier tests I had logged similar speeds throughout various locations in the office.

Presumably since the update to iOS 7.1.1, I am still able to measure 11 to 13 kbps in close proximity to the router, whereas about 25ft away (without any significant obstructions that may shield my reception), the wifi speeds drop to 0.5 to 1.0 kbps.

Surprisingly, my room mate who owns the same model iPhone and runs the same iOS version does not seem to experience these issues.

A visit to the apple store and a preliminary diagnostic test there only revealed that the wifi antenna itself seems to be fully operational.
