You may drop into one of the below situations after updating to iOS 11 final version today. Of course, these WiFi not working problems may also happened in iOS 10 on your iPhone iPad and iPod touch.

Why iPhone Wi-Fi not working sometimes?

The WiFi requires 3 parts, the router, your device and the Ethernet network, which play important roles. If any of these parts goes wrong, the Wi-Fi won’t work on your iOS device, whether in iOS 11 or iOS 10.3.3/10.3.2.

For example, you won’t get a fast WiFi surely if the network is so slow. Besides, if the router was incorrectly set up to connect the Ethernet, you definitely can’t surf online and play online games but you may get a full WiFi signal on your device.

  • If you are using iPhone 7 or iPhone 7 Plus: Press and hold both the Sleep/Wake and Volume Down buttons for at least ten seconds, until you see the Apple logo.
  • If you are using iPhone 6s and earlier, iPad, or iPod touch: Press and hold both the Sleep/Wake and Home buttons for at least ten seconds, until you see the Apple logo.

Many users report that they solved their iPhone Wi-Fi problems in iOS 10 by disabling Wi-Fi Networking service under Settings > Privacy > Location Services > System Services.

    1. Why? Because im just realising Apple dont really care. 30% bug, wifi, bluetooth. Not addressed any of these issues. Samsung s8?

  1. 10.3.1 avoid avoid avoid the wifi issue is worse then ever drops out constantly and shows as wifi is connected! Back to android for me

    1. 🙁 same issue here pm 10.3.1. Wi-Fi keeps turning off and resulted in huge cell data usage even when near the Wi-Fi AP. Was find before this update.

    1. Yes! Same here… wifi is greyed out and I can’t even click it to select a network. iPhone 6 Plus 10.3.1

  2. I found this to be a problem only on an iPad Pro device (regular iPad and iPhones continued to work fine). Turns out that after the update to 10.3, the Pro refused to connect to the 5GHz network. I created a separate SSID for the 2.4GHz network on the same router and voilà—the Pro connected without a problem. Of course before I tried that, I had exhausted all other options including resetting the network settings on the iPad and reinstalling the OS. If that works for you, please reply to this comment as I would be curious to see if others were affected in the same way. Thanks!

  3. None of these tips fixed the problem. My iphone 6 and can only get wifi when my phone is sitting on top of the router. We can’t afford to buy a new phone and I don’t have a data plan. I hope this issue is resolved soon.

  4. My iPad 4th gen WiFi only can no longer turn on WiFi or Bluetooth, tried all of the above suggestions, cannot do a restore because I cannot turn off ‘find my iPad’ due to not being able to connect to the server, tried all methods whilst cabled to macbook still no joy.
    Well done apple, you killed off my iPhone 4, you’ve now killed my iPad, the macbook is is staying on its original os just in case!!

  5. me too, my i phone 6 began forgetting the pass words of the works place WiFi and remembering the home WiFi password after a couple of days the home password also forgotten , then began to come and goes rapidly , then i must enter the pass word when i enter the pass word i got a question again enter the password ????? today my iPhone is not seeing any WiFi around absolutely is blind , thank you apple at last i will get a rest from re entering the pass word !!! thank you

  6. My wife has had same issue since upgrading to iOS 10.3.2 on her iPad Air. After trying various tips here and elsewhere to no avail I noticed that there was some new option under Settings about switching on 2 Factor Authentication which she had not done anything with. I drilled into this option and chose the Do NOT to enable now (or words to that effect) option. After this hey presto the wifi response time suddenly soared from around 1 Mbps to 36 Mbps. No idea what happens if you choose to switch this option ON but with it OFF it has defo fixed this issue. 😜Come on Apple we shouldn’t have to do your legwork for you ☹️.

    1. Hello Camille,

      You mean that you have tried all methods, like Reset Network Settings?
      And you have restored your device twice?
      And did this problem happen after updating to iOS 10.3.2?

  7. I’ve restored my 6 plus 10.3.2 three times and tried every other fix you mentioned multiple times. Wifi toggle is still greyed out. Any other suggestions?

  8. i have the same problem. when i try to connect to wifi it says “incorrect password”, but im very sure i have entered the correct password. what i noticed is that i can only connect my iphone to wifi without any problem when i am near the router and it works very fine. so i think its a hardware issue but i dont know how to solve it.

  9. Same problem here too. If you ever went to Apple Store, they would do their in-store wi-fi test and suggest a total system reset. I did it many times and the problem were the same. Then, they would do a hardware exchange and it had the same problem again. Does Apple ever admit they have a problem? With the wifi on & off, the phone became unusable.

    1. Thanks for your sharing. Agree with you, now there is no effective way to fix this common issue except resetting device. And I believe most of these issues are software ones, not related to hardware.

  10. iOS 10.3.2 on an iPhone 5s and iPad here having the symptoms mentioned above.
    My 9y old daughter found out the following workaround on her iPad when it once again forgot my (hidden) WiFi and not wanting to enter my horrible network password again:

    On the device go to Settings > Wi-Fi
    Under “Choose a Network” pick “Other”
    Type in the name of the hidden network, don’t select a security option, just press “Join”
    A dialog appears stating “Unable to join the network “xxx-yyy””, close this by pressing “Dismiss”
    Go to the previous screen by pressing “Cancel” in the upper left corner
    As if iOS suddenly remembers the hidden network, it is joined!

    This makes me think iOS doesn’t bother to look for (stored) hidden networks. By trying to join it without entering any security settings (we don’t want to overwrite the stored entry), it is forced to look for it and “remembers” having seen the network when we get back to that Wi-Fi Settings page.

    So dear iOS developers, please make iOS scan the stored networks list every now and then in your new release and help me last a little longer with my cell data bundle.

    Regards,

    Erwin

  11. I turned my iPad Location Services off, Wi-Fi off and restarted. I turned Wi-Fi on and re-entered my password leaving location services off. That worked. Might not have needed the restart but I wanted to start fresh. This is getting tedious Apple…..

  12. Not only the WIFI, LTE also slow. Not normal slow, it’s extreme slow. I am going to return the iPhone 7!!!
    Apple haven’t test it? iPhone price is double or triple the android phone! WTF Apple!!!

  13. This issue just arose for me. Have had my 7 plus for almost a year and suddenly i get a message saying that my wifi password is incorrect. It is very disappointing being that i live in a rural area, and wifi is the only way i have service at home.
    Also my 4g LTE is very spotty at best.

    None of the above mentioned “fixes” work for me. The phone will decide when, and if it will connect to wifi, or if it will connect to 4G LTE.
    Very disappointing.
    I was a longtime android/samsung fan that jumped ship last year and purchased my first iphone, and within a year it has become a $1200 ipod touch with little to no use.

  14. iPhone se network unavailable, can’t place calls or send texts after 10.3.3 update. I am able to get wifi, but it drops frequently. I tried all the fixes out there including restore, except taking out the battery and changing the sim card. So I can’t verify with itunes to get my apps back. I cancelled my autopay on my pay as you go net10 service as it was about to be withdrawn for the month and I didn’t want to pay for a non working phone, so at this point it would be unavailable anyway. Makes fixing a bit more challenging. I’ll probably try the apple store in my neighborhood when I’m off. These phones are way too expensive to be having these issues.

  15. So an issue introduced by an IOS update, experienced only after an IOS update and only fixable by fixing the bugs in the IOS update, is by the definition of the solutions here, an issue that is nothing to do with IOS and something wrong with hardware and apps that were working fine before the IOS update?!! Come off it guys, even my non-technical grandmother can tell you are clutching at straws here. The real problem is that quality control of software and hardware release from Apple is slipping and they are getting away with murder.
