Problem #1: iPhone X has no internet connection when using work wifi

iPhone X says connected to WiFi but internet connection does not work. Gives an error message when searching on safari and says connection lost. iPhone works with other WiFi networks fine. It just doesn’t work with my WiFi at work. The WiFi at work works fine with everyone else’s devices, just not mine. I tried doing a hard reset, reset network settings, reset all settings, and turned WiFi on and off numerous times. — Lacie

Solution: Hi Lacie. An issue like yours is usually fixed by simply resetting network settings. If the problem is still there even after you factory reset the device, that means there’s no problem with your iPhone. The problem must lie on the router or how your work wifi is setup. Your iPhone may be intentionally or unintentionally blocked for some reason. If this is a corporate wifi, you should talk to your IT people so they can allow your iPhone X to use the internet.

Problem #2: iPhone X mobile data won’t work

I just got a new iPhone X, replacing my older iPhone 5s.  With the 5s, internet connectivity was not a problem; if I did not have access to a wireless network, it would use the cellular connection to connect to the internet. My iPhone X does not seem to do this.  It connects just fine via my home network, and my work network, but will not connect via the cellular network. I have activated Cellular Data and turned on the “roaming” feature. I have turned on Location Services.  Nonetheless, I cannot post to Facebook when away from the two networks, I cannot receive Facebook Messenger messages, and my map app does not seem to be able to locate me. — Joshua Summit

Solution: Hi Joshua. Mobile devices must have the correct APN settings in order to allow to use a network to connect to the internet. If this has not been set up properly, mobile data service will not work at all. To know how to set the APN settings up, contact your operator and get the step-by-step instructions. If you’re on a GSM network, your iPhone should set the APN up properly after you insert the SIM card. If you’re on a CDMA network though, there’s a more complicated setup process that your operator must do to make cellular data work.

One other important thing to note here is that  you need to be subscribed to cellular data as a network service in order to use it. We don’t know if this is exactly what you mean when you said you have activated Cellular Data. if it does, then contact your operator and seek their guidance on the matter. If what you mean by activated cellular data is to simply tap on mobile data function on your phone but is actually not a paying customer, you’ll obviously not be able to use mobile data on your iPhone. Again, you want to talk to your carrier for support.

Also, roaming is only applicable if you are outside your network (like when you’re out of country). Turning it on while you’re actually still using your carrier’s network may create a conflict and cause connectivity issues. Roaming service is an agreement between your carrier and other carriers to allow you to be able to send and receive messages, use the internet, and do voice calling while you’re using a third party carrier network. Unless you’ve activated roaming feature before you left your network, this will not work. If you are abroad or using a third party carrier network right now and you did not activate roaming service with your carrier beforehand, this may be the reason why you are unable to use cellular data at all. To shed light on the matter, make sure that you call your carrier.

Problem #3: iPhone X keeps saying “not connected” error when on wifi

iPhone X. Every time I look my phone is in LTE…I go into settings and WiFi and it says “not connected” then there in the list is my home internet (ATT) and I choose it —and within 10 min it switches back over to NOT CONNECTED or I get the options on my screen as to which internet I would like to choose. So strange bc two others in the home are not having any issues so it must just be with my device. Can you walk me thru what I need to do? I’ve tried turning off and on again and still same problem. SOS. — Peggy

Solution: Hi Peggy. If your iPhone X is having difficulty connecting to your home wifi, below are the potential solutions that you can do.

Solution #1: Perform a soft reset

Some bugs are fixed by simply doing a soft reset, also known as forced restart. Soft reset is a fancy term for another way to reboot your iPhone. It is usually recommended if an iPhone has frozen or has become unresponsive. A force restart won’t erase the content on your device. You can force restart your device even if the screen is black or the buttons aren’t responding. Follow these steps:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Then, press and hold the Side button until you see the Apple logo.

Solution #2: Verify if wifi is working on your device

Is your iPhone X only having an issue connecting to your home wifi network? If you are not sure, try to connect it to a friend’s or a neighbor’s wifi and see if it works. This is the simplest way of determining whether there’s an issue with your home wifi, or on your phone’s wifi function.

If your iPhone X will connect to other wifi networks, that means it’s probably blocked in your home wifi. If you are not the administrator of your home wifi, make sure to talk to the right person so it can be allowed to connect to the internet again. If you are the wifi administrator but don’t know how to check your router settings, contact your internet service provider and let them troubleshoot the issue.

On the other hand, if your iPhone X will not also connect to other wifi networks, there must be an issue with its software or hardware. To know if you can fix it on your end, continue following this guide.

Solution #3: Reset network settings

Resetting your iPhone’s network settings is the next logical troubleshooting step that you can do in this case. This step will delete all network names, passwords, and configurations, including VPN settings if you have them. Make sure that you know how to connect to the wifi networks you’ll be deleting by knowing their passwords ahead of time. The same is true if you are using VPN service.

Once everything is set, follow the steps below on how to reset network settings on your iPhone X:

  1. Tap Settings to open the app.
  2. Tap General.
  3. Tap Reset.
  4. Select the option to Reset Network Settings.
  5. If prompted, enter the device password.
  6. Confirm action.

After the reset, the connection status of your device will set to default or similar to when your iPhone was being powered on for the first time. Airplane mode is set to OFF, Bluetooth is turned ON, Data roaming is OFF, as well as Mobile Hotspot and VPN. Wi-Fi and Mobile data are set to ON.

Solution #4: Reset all settings

When you reset all settings on your iPhone, all customized settings are restored to default values. Personal data including sound settings, display settings, network settings, and other custom settings won’t be affected though. Follow these steps to reset all settings on your new iPhone:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Tap Reset.
  4. Tap Reset All Settings.
  5. If prompted, enter the correct passcode for your device.
  6. Tap the option to Reset All Settings to confirm action.

Wait for a few minutes until the reset and reboot processes are finished.

Restoring your iPhone to default settings also helps in fixing device issues like random crashes, abnormal reboots, and apps freezing or lags.

Solution #5: Factory reset

As a final solution option, factory reset is also the most drastic procedure that you can do on your iPhone X at this point. This will delete user data and contents, apps, and customizations. Make sure that you back your photos, videos, documents, etc before doing it.

To factory reset your iPhone X:

  1. Open Settings app.
  2. Tap General.
  3. Tap Reset.
  4. Select the option to Erase All Content and Settings.
  5. If prompted, enter the correct passcode for your device to continue.
  6. Tap the option to confirm action.
