Wi-Fi not working on iOS 8.4

Hi,

I had problems on iOS 8.3 where Wi-Fi worked at the beginning, but then stopped. Sometimes iPhone 4S attempted to connect, I saw wifi icon and then it disappeared. I tried Reset Network Settings, I managed to setup Wi-Fi connection again, but it worked for a few minutes and then again the same issue.

I was hoping that the issue will be fixed on 8.4, but now it's worse. After resetting network settings I cannot even join wifi network. After entering password, it says "Unable to Join the network. I have correct password, because I'm using it for other devices.

I tried to restore iphone through iTunes, but I cannot do that, because I'm getting error message "Find My iPhone" must be turned off. The problem is that I cannot turn Find My iPhone off in iCloud settings on the device, because Wi-Fi is not working. Now I cannot restore iPhone and I cannot setup Wi-Fi.

Another issue is the fact that device may not have 8.4 installed. Although it reports version 8.4, the device didn't show locked screen after update, like it did on iPad. It seems that device only shows version ioS 8.4, but hasn't really been updated, otherwise I would see locked screen after restart.

Is there a way to force iOS 8.4 update again on the device?

How can I fix wi-fi problem? Wi-Fi scanning seems to be a little slow. On that page the device often freezes for 20 seconds or so. The quality of iOS and Mac OS X has gone down dramatically.

I have $800 iPhone 4S, which has the antenna problem and I don't think I want another Apple device, if I can get Android device with better spec than iPhone 6 for $200. Over 3 years I made around 50 calls with this device and I'm not using much. I'm just using password manager app and need wifi for sync and backup.

You know what, forget this, because no one is going to fix/revert wifi code back to what it was on 8.0 or older.

iOS 8.4 with broken wifi also drains battery. In 3 hours battery capacity dropped from 100% to 73% (loss of 27%).

I recommend users who experience wifi issue to completely disable wifi until Apple fixes the problem. It looks like device is occasionally scanning wifi networks while in sleep mode.

After you disable wifi, avoid enabling it again or even navigating to the wifi settings. The device may freeze. In that case you need to press and hold power button and home button at the same time. When the devices shuts down, power up again and don't try to change wifi setting, leave it off.

I think the device must be doing something on the background that causes high CPU usage, device slows down and after a few ore seconds it freezes completely. Clearly some multi-threaded deadlock in wifi or networking routines.

I Already did the usual tactics and resetting. My wifi router is on the 2nd floor, and i loose connecting when i am on another floor. This never happened with previous ios version, from 7 up to 8.3. Phone doesnt even bother to search for wifi. Oddly enough it sees the wifis from 2 houses over, but it doesnt find my own.

I Always get ****** when something stops working after a change, which clearly isnt caused by myself in this matter.

When you took it to the Apple Store, did it work OK there?

OMG! I also can't connect successfully with my router unless the phone is directly beside the router. Whatever Apple did in this latest update is causing the same WiFi issues throughout. Are these problems exclusively to the iPhone 5/s/c? If so, maybe the plan is too "push" people towards the newly released 6.

What happened when you tested it at the Apple Store?

The nearest Apple Store is 2 hours away! Even though I live in a city/area with over 375000 people! I'm sort of in a quandary as to what to do, outside of dIrving 4+ hours round trip!

With my iPhone 6 I could not connect to my own WiFi, nor could I connect to my husbands phone if it was on hotspot - in fact I could not see either WiFi option nor could I enter it manually. I could connect to WiFi's if it was a 5ghz router. I was also having Bluetooth issues - if it did connect then the music was jittery and so was any phone call. I have tried everything even a factory reset. I used apples chat and spent hours and hours talking with them both on chat and by phone. I have ended up getting a new phone and it arrives probably tomorrow. I'm not sure that mine was related to the update or more a coincidence. Use apple chat if you can - I didn't pay for it I selected the exception option and pick hardware issue and could chat with them every time.

Interesting. Thanks for your response, letting us know we're not alone in this mess. However, while you chatted hours with Apple Support, they did not give you a solution, other than "buy a new Phone".

Fingers crossed the 8.4.1 update gives a solution.

Jul 25, 2015 11:16 PM in response to Joker1974

Apple replaced it when we ran out of things to try - didn't cost me a cent.

Jul 25, 2015 11:53 PM in response to davemegan

Aha, but my old "5" isn't on any warranty anymore. Still odd, that your 6 was messed up, and a new 6 is doing ok? If so, a clean install of 8.4 seems to be ok, compared to updates from pre 8.4 to 8.4 on existing machines. Kudos to Apple for putting out a working "update"..

Jul 26, 2015 1:17 AM in response to Joker1974

My new one should be with me tomorrow so will know soon. I think my old one really just had a fault but yes happy that Apple replaced it. Kudos to them 🙂

I too have a 5, how do I get a "working" update. I'm thinking I have to connect to iTunes and do a complete restore.

Megan I would love to know how your new phone is working. I'm struggling with this issue myself...

My wife has an iphone 5s and my work phone is a iphone 5. Both running 8.4 with no wifi or bluetooth issues. My personal phone is an iphone 6 running 8.4. Until this update everything worked great. After the update it cannot hold a wireless connection unless I'm <15ft from the router. My bluetooth pops and hesitates while playing music in my car. This is music that is downloaded to my phone, so it's not trying to stream off 4g or wireless. Not sure if this matters but my iphone was one of the first. I preordered the first day and got the 2nd wave of shipments.

So far I've reset my network settings with no luck. I then performed a full system reset then restored from backup... twice. Still no luck. Now I'm considering doing a full system reset and reloading all apps hopefully over a fully functioning wireless. I know it's not my router as 2 other iphones running 8.4 and multiple other devices are all running fine. The bluetooth shows me it's software, not hardware. I'll continue to update as I try more things.

Best of luck everyone who has this issue.
