Problem 1: iPhone 7 won’t connect to home wifi

My new iPhone 7 will not connect to my wifi. All my other three devices connect to it with no problem. I have followed your trouble shooting guide.  The phone connects to other wi fi networks but not mine with EE.  I have rebooted both phone and router. I have had my service checked with my provider. They also got me to delete the network settings (your step 3). I then had to go to the Apple store to get a back up and reset as I had no wifi to do it at home. (your step4).  But my phone would still not connect.  My network provider then gave me a new router but the phone will still not connect.  The phone shows the name of the router but in the first case it kept saying the password was incorrect. With the second router it again shows the name of the router but will not bring up password access and the wheel just keeps turning forever.  I don’t know what I can do now. I am at my wits end as no one seems to know what is wrong and neither my network provider or Apple will take responsibility. Please can you help me? — Amanda Thomas

Solution: Hi Amanda. Since you’ve already done almost all troubleshooting steps for this case, we suggest that you try one more thing, which is to wipe the phone clean and start fresh. We think you simply restored the device from a backup when you went to an Apple store so what you want to do now is to start it fresh. That means turning erasing everything and not re-installing the same set of apps and contents afterwards. This will eliminate possible content/app that may be interfering with your phone’s wifi function. To do that, you need to do the following steps:

  1. Sign out of your iCloud account (if applicable).
  2. Go to Settings.
  3. Tap General.
  4. Tap Reset.
  5. Tap Erase All Content and Settings.

Once you’ve wiped the phone clean set it up again but make sure not to install anything. Just try to see if your phone’s wifi will now work normally. If it still fails to connect, consider getting a phone replacement.

Problem 2: iPhone 7 won’t connect to wifi or mobile data, how to turn off find my iPhone

My iPhone 7 will neither connect to my wifi network or my normal data. I have done the best i can to achieve this but to no avail. I was in order to update or restore my iPhone 7 to a new phone that i would need to turn off my find my iphone. The question is how can i turn off my find an iphone without my phone connecting to internet..i was told to login to my iCloud and remove my device attached to my icloud account…i tried this means as well but all efforts have been proving abbortive. Here is my personal email address.. Adenosebamidele

Solution: Hi Adenosebamidele. iOS devices like your iPhone is protected by a security feature called Activation Lock. This feature ensures that your personal information stays secure in the event that your device is stolen or lost. If you want to turn off Activation Lock, you can try using another device like a computer or another iPhone. Here are the steps:

  1. Sign in to iCloud.com with your Apple ID.
  2. Go to Find My iPhone.
  3. Click All Devices at the top of the screen.
  4. Select the device that you want to remove from iCloud.
  5. If necessary, click Erase [device].
  6. Click Remove from Account.

Once you’ve removed your device under your iCloud account, you can then start the Restore process. Here’s how:

  1. Create a backup of your files. You can do that in a number of ways but the fastest and most effective way is by using iTunes in your PC or Mac.
  2. Connect your iPhone to your computer with the cable that came with your phone.
  3. We assume you remember your phone’s passcode so simply enter it when you’re prompted for it.
  4. Select your iPhone once iTunes asks you for the specific device.
  5. Once you’re in the Summary panel or screen, select the option that will restore your device (Restore).
  6. Confirm by clicking on Restore button.
  7. Wait for a few moments while iTunes restores your device to its factory settings. It may also take some time if iTunes will need to install an updated operating system version.
  8. After this factory reset, all software settings should be restored to their defaults.

As the answer to your question, no there’s no way to turn off Find my iPhone if your iPhone 7 can’t connect to the internet in the first place.

Problem 3: iPhone 7 can’t detect network signal abroad

Hi. My issue with my iPhone 7 Plus is it will never pick up a network signal when I go abroad. I’m with same carrier as my husband and he has no problems. He’s got an iPhone 7. I’ve tried the workarounds apart from resetting factory settings as I’m not sure the effect it will have on my phone. I’m due to go abroad again next week so would like to solve problem before I go. Please advise. — Debbie Jones

Solution: Hi Debbie. In order to allow your device to use a third party network when you’re abroad, roaming must first be set up on it. Roaming service must be enabled by your home carrier ahead of time (before you leave their network) in order to work. Because not every carrier uses the same cellular technology, there’s a chance that your phone may not be compatible with a network where you’re going. Be sure to ask your carrier if your device will work in a particular country using a specific network so they can advise you accordingly.

Hardware consideration can also be one reason why your phone won’t pick up any signal at all. Carrier signals are transmitted in a certain frequency and if your phone’s radio is not compatible, there’s nothing that you can do about it. Even your carrier can’t help you. Again, be sure to talk to your carrier or do your own research ahead of time regarding the network you’ll be using when you’re abroad.

Problem 4: iPhone 7 wifi won’t work

Hi. I have the iPhone 7. one day i made the software upgrade, and after this, i am not able to connect to the wifi. it is gray, and i can`t move it. i waited until the next software update comes, made it, and still not working. people told me, it is a hardware problem. as i had still a guaranty, i sent the phone back, after i safer everything as a backup in my iTunes. the phone came back, they said it is fixed, i made the backup, and same problem. i brought the phone back again, got a totally new one. made the backup with that one, same problem. wifi is grey, and i can not connect as i can`t move that button. what is interesting is, that if i make a backup to an older version from one year ago, the wifi is working, but all my datas from one year are missing. so it can not be a hardware problem, but a software problem. i several times reseted my phone completely, all datas off and on again, nothing helps. i am surfing in the internet on my macbook, tried out every reset options, nothing works. do you have any ideas i could do, or simply through it out of my window? Many thanks. — Sebastian

Solution: Hi Sebastian. This is clearly not a hardware issue. We think that the latest backup you keep on reinstalling is the cause. An app or content in that backup must be preventing wifi to work. We suggest that you restore the phone as a new device only. DO NOT restore from the backup that’s causing the problem. If you want to check if it’s an app problem, install them individually and make sure that you observe how wifi works after adding one. This is the only effective way to identify if an app is causing the wifi to stop working or not.
