Q: 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.

MacBook Air (13-inch Late 2010), Mac OS X (10.7.2)

A:

Potential solution to Wi-Fi problem (at least until Apple fixed the real issue)

-------------------------------------------------------------------------------- -------------------

Wi-Fi on iOS is really horrible. So far my iPhone and Wi-Fi is working after disabling "Find my iPhone", so I didn't even need to restore the device through iTunes. But it was painful process to get it working. Originally I wanted to restore iPhone, but iTunes prevented that, because restore needs "Find my iPhone" to be disabled. However you cannot disable "Find my iPhone", if you don't have network connection.

From all this it's clear that some didn't think it through. It is true that "Find my iPhone" is there to prevent unauthorized user to disable this feature, so that owner could potentially find the device. I guess that's also the reason why restore of the device is prevented when "Find my iPhone" is enabled. But there has to be  a better way to handle this, for example owner of iPhone could mark stolen device as "Stolen" on Apple's website and when some restores the phone and goes online to get updates through iTunes, it should be possbile to block the device based on it's serial number. This way "Find my iPhone" does not have to block "Restore" process.

 

After a little rant here is how to fix your phone, until Apple fixes real Wi-Fi problems:

 

Goal: The goal is to disable "Find my iPhone", which is impossible if your Wifi (or 3G/4G nework, as some users reported) does not work.

Reason: It is very likely that Find my iPhone and perhaps other services break Wi-Fi connection or networking in general. Perhaps wifi daemon cannot handle correctly parallel access to network resources.

How: You have to connect to Wi-Fi at least for a minute so you can disable "Find my iPhone".

Hint: You may need to reboot the device several times. I had to do it around 7 times, just to get wifi scanning to work.

 

1. Shut down your device completely by holding power button and then sliding Off switch. If that does not work, hold power button and home button until the devices shuts down. Start up your iPhone again.

2. Navigate to Wi-Fi page and try to connect to your router. If the device cannot connect or cannot find networks go to step 3. If you are connected go to step xxx.

3. On Wi-Fi settings page  disable wifi  by moving the switch to OFF position. This may not be as easy as it sounds. The device may continue scanning for available networks and any screen update may be very very slow. If you navigate back too soon before the information about position of the switch is saved, then the device does not actually switch Wi-Fi off and when navigating back it starts scanning again. Of course this is undesirable, because at this point networking is in bad state and it never connects. The device sometimes freezes. When I left fully charged  device overnight, the battery was dead in the morning (after about 8 hours in sleep mode). Another indication of bad device state is inability to navigate back from settings while Wi-FI switch is in OFF position. Even pressing home button doesn't work and you cannot leave Settings. In this case you may need to switch Wi-Fi On again and then try to switch it OFF again. Every time you change the switch, you may need to wait (for a minute or more) so that new setting is actually applied. If nothing works and you cannot positively change the settings, you may need to go to step 1. reboot the device and repeat the steps until Wi-FI is OFF. If you finally have Wi-Fi turned OFF, navigate back and leave Settings.

4. Now that Wi-Fi is OFF shutdown the device and reboot again.

5. Navigate to Settings > Privacy > Location Services > System Services and turn off following services: Location based iAds, Share my location, Spotlight suggestions, Wifi networking and Frequent locations. It is surprising, but you actually don't need wifi networking enabled here in order to connect to wifi (if I remember it is used to provide shared access to wifi to the other services/background tasks). Disabling these services help to keep eliminate parallel requests for networking. At this point you cannot disable "Find my iPhone", because you are offline.

6. Navigate to Settings > Wi-Fi and switch Wifi ON. See if scanning works and device can find your router. If you see your router select it. If you had problems before, you may need to actually tap on icon and  on DHCP tab enter into DNS field 8.8.8.8 (Google's DNS if I remember correctly). If your router is not found and you cannot see any other networks, that means the device or rather networking is in bad state, scanning is broken and you need to go to step 4 and  reboot the device. If you see networks in the area including your router, select it and enter password. If the password is not accepted or you get message like "Unable to connect", you may need to repeat everything from step 4. It can also help you to configure your router to channel, which is not used by any other router that your device can see. Routers usually use default channel 11 or similar (although manufacturers now started to assign different default channel on each router). Newer routers use Automatic channel assignment. Do not use this feature, if your iOS device cannot connect even after 10 reboots. You may need to set channel manually on your router, it looks like iPhone wifi scanning has problems when more than one router uses the same channel. Hopefully by now you are connected to Wi-Fi. Proceed to step 7.

7. Before your Wi-FI connection goes down again !!! quickly !!! navigate to Settings > Privacy > Location Services > System Services and disable "Find my iPhone". The device will actually connect over the internet and disables the service online, then it disables the service on your device. If that is successful. Your Wi-Fi should be working again.

8. Optional steps: Go to Settings > Privacy > Location Services > System Services and enable Wi-Fi Networking, Frequent Locations and if you want Spotlight and iAds (although I left these off).

 

Good luck !!! You are going to need it.

    Yeah pretty much. Don't get me wrong, I love using iPhones. Had one ever since the first one was launched. But I've tried all the solutions and I really need my wifi to call overseas.

    Are you serious?  A suggestion was made to assist the OP in resolving the problem and you want to start a debate.

    Jul 8, 2015 5:01 AM

    What you you done to resolve the issue yourself?

    Jul 9, 2015 9:05 AM

    So you're not looking for assistance? You're posting here merely to rant.


    1. Ok. Since you are not able to acknowledge the sentiment here let me explain it to you. Consumers have the right to expect working products from corporations. In the UK for example there are specific laws to this effect that supersede manufacturer’s warranties. When that does not occur consumers are left frustrated. We are entitled to be frustrated. I replaced a 5 with a 6. Why? Because the 'Genius' at the store told me that it was my Airport Extreme and sold me a new one - only that did not work and neither did 'switch it on and off', reboot, software updates, back-ups, new routers, etc. As has already been explained to you, we do not all live around the corner from an Apple store either.

    If you are involved with Apple and I am guessing that you are, you know that there is an issue with the product. Because of the financial implication apple will not acknowledge it because that admission would mean that that they will could be held legally accountable.

    In the software industry this type of rushed delivery often leads to lawsuits and not for $1 or a million - it is normally much larger than this and settled out of court to avoid publicity. Problem is, until this results in a class action lawsuit, apple like all other corporations will not acknowledge a problem because they are not going to be taken to court by a person that used his saving to buy his phone. Think about the tip sheet from your vehicle insurance - Never say you are sorry, never admit guilt...

    The point? People have the right to expect a working product. Apple put themselves in the spotlight when they knocked Microsoft around 2005 with their upgrade adds and are now the ones with the unreliable product. The people on this tread are here not because they are bored and trolling, they are here because they had a working product, were told that 8.4 was needed to address security issues and now they have $nnn issues. This is wasting our time because Apple has apparently forgotten what a software test cycle looks like.

     

    And by the way, you started the debate or did you just expect to make snide remarks and rely on everyone on here being to well mannered to take you to task?

    I couldn't have summed it up any better. I have been experiencing slow wifi since ios 8 and now i'm unable to connect to the wifi in ios 8.4. I don't have much time to visit the genius bar since i go to work everyday and come home very late at night. I spent all of last night trying out various fixes but none of them seem to work. If anyone can suggest any fixes that would be great. Much appreciated.

    Yes seven days a week from working 2 jobs. I would appreciate it if you could help fix this wifi issue instead of commenting random responses. Thank you.

    It's not a random response.  Very few individuals work long hours seven days per week.

     

    Now, with your situation, I have no idea what can be done to fix your problem.  Clearly you have an Apple product that is not functioning properly and it's not reasonable to expect Apple to fix it without you getting it to them.  You wouldn't expect a car dealer to fix your car while it's in your garage.

    HI,

     

    Try erasing all content and settings via Settings -General-Reset-Erase all content and settings

    Reinstall IOS 8.4 via connection to Computer through which you are able to sync to ITUNES; holding down the OFF and HOME buttons while you are in ITUNES.

    Then, disconnect from ITUNES and turn off Location Services via Setting-Privacy.

    Then, turn off the iPhone.

    Then, turn on the IPhone, and turn back on Location Services

    Turn off Find my iPhone.

    Then, go to Wifi in Settings and try to reconnect to your network.

    Leave Find my Iphone off

     

    Hope this helps

    I tried this "try resetting your network settings. Go to Settings>> General>> Reset Network Settings."

    (from http://en.yibada.com/articles/43219/20150706/top-5-ios-8-4-bugs-problems-how-to- fix-them.htm

    You'll need to reset your Wifi password.

     

    I'll update this after trying the reset.

    I havd been having occasional wifi dropouts since IOS 8.0, on my iPad, but at least it was occasional. Wifi has been very slow, but I was able to tolerate that. Since I installed IOS 8.4, however, my wifi drops out constantly. Often it comes back on its own, but just as often I have to jump through a few hoops to get connected again. My daughter has not updated her iPad to 8.4 and is not having these wifi issues. That tells the tale right there doesn't it!?

    I have refrained from updating my MacBook Pro from Mavericks, because I have heard of so many issues with Yosemite, and the wifi connection on that has remained speedy and constant. Glad I didn't update that now!

     

    By the way, during the brief time it took me to type this reply, on my iPad 2, my wifi dropped out 5 times and reconnected on its own.  :-(

    The wireless connection problem with my Iphone 6 started today after the upgrade to iOS 8.4. Ignoring the network on the phone didn't work, it found and tried connecting to it over and over anyway. I then changed my WLAN from 2,4 to 5 GHz, which was probably totally irrelevant, and then hid the SSID, so I could eventually log in from my iPhone manually. That did the trick, at least for now.

    Hi,

     

    How do you hide the SSID?  And then what do you mean you log in from your iphone manually?  Sorry, not very computer literate, so I need step-by-step directions.

     

    Thank you!
