How to fix an iPhone X that won’t connect to wifi after an update

When it comes to wifi problems, it’s important to remember that there are two possible scenarios you’ll encounter. One is the possibility that you have a device (iPhone) issue and the other is that it may be router problem. Under the first scenario, you can further break the possible reasons down to either a software issue or a hardware issue. If it’s a software issue, there’s a big chance that the problem is user-fixable. On the other hand, a hardware issue will most likely require a Visit to an Apple Store to schedule repair or replacement.

Verify if iPhone X cannot connect to all wifi networks or just one

The very first thing that you want to do now is to determine whether your issue has something to do with a specific wifi network only, or if your iPhone is unable to connect to any network. To do that, try to connect your device to another wifi. You can go to your friend’s place, visit your favorite cafe, or use your local library.

If your iPhone can connect to another wifi and internet works as expected, that’s an indication of a router problem. In this case, you’ll need to troubleshoot your router and probably ask the help of your internet service provider.

If no wifi network will work with your iPhone X, you clearly have a device issue. It’s time to troubleshoot your iPhone X.

Fix #1: Powercycle

iPhones are designed to automatically remember wifi details — usernames and passcodes — though there’s no way to check for these information like in a Mac or PC. Still, having this feature comes in handy because that means your iPhone will no longer nag you to enter your home wifi credentials when you arrive from work. Sometimes, this feature can also be a source of frustration when there’s some modifications done to a wifi network. At times, routers and connected wireless devices may lose sync after installing a router update, or after changing some features. Bugs can also develop out of nowhere. In most cases though, minor connectivity gitches in a network can be fixed quite easily by simply performing a power cycle, which is just a fancy term for restart. If you haven’t tried it yet, here’s how it’s done:

  1. Turn off your iPhone and all other connected devices.
  2. Turn off your networking equipment such as modem, router, switches, etc.
  3. Wait for 45 to 60 seconds before turning on the modem or router.
  4. Wait for the modem or router lights to be full. Some networking equipment can be slow and it can take after 2 full minutes for them to initialize properly.
  5. After some time, turn your iPhone X and other wireless devices on and check wifi connectivity.

Fix #2: Forget the network

If a network powercycle won’t help, the next good thing to do is forget the network. We assume that your iPhone X is already connected to your wifi network before this issue occurred so what you have to do head over to Settings > Wifi and tap the blue circle with an i. Then, find the Forget this Network option and tap it.

Once you’ve disconnected from your wifi network, wait for about 10 seconds before reconnecting.

Fix #3: Toggle wifi on and off

While in this section, you can also do one quick step, that is to toggle the wifi switch from on to off and back to on again. Some users find this easy trick helpful in re-initiating good connection to a wifi network.

Fix #4: Reset Network Settings

If the issue is still unresolved, the next step is to clear all network information on your iPhone. A database of past wifi networks is being maintained by your iPhone and sometimes, information may get outdated or corrupted. Deleting this database sometimes fixes wifi problems so be sure not to skip this step. Here’s how:

  1. Open Settings app.
  2. Tap General.
  3. Tap Reset.
  4. Tap Reset Network Settings.

After wiping the network database, your iPhone will ask you to enter your wifi password. If it still won’t connect to the internet after that, proceed to the next solution.

Fix #5: Reset All Settings

Knowing what is the exact cause why your iPhone is unable to connect to wifi is very challenging due to the fact that, unlike other platforms such as Android, user-level access to the software is very limited. This makes it simple for users but a huge disadvantage for people wishing to go deeper in troubleshooting. Your case is no different. There’s no way to know if this glitch is due to an app, a setting, a misconfiguration, or a software bug. The best that we can do is to troubleshoot blindly and hope that we’ll across a solution. For this reason, the next good thing to do is to try and reset all settings. It’s a logical next step if resetting network settings won’t help.

To reset all settings, do the following:

  1. From the Home screen, go to Settings>General>Reset.
  2. Tap Reset All Settings.
  3. If presented, enter the passcode.
  4. Tap Reset All Settings to confirm.

Fix #6: Factory reset and Restore

If all the solutions above won’t work at all, you have no other choice but to do a drastic step of resetting the device back to its factory version. After that, you should set it up as a new device (and not restore from old backup) to see if there’s a difference.

To factory reset your iPhone X, follow these steps:

  1. Open Settings app.
  2. Tap General.
  3. Tap Reset.
  4. Tap Erase All Content and Settings.
  5. If prompted, enter your passcode.
  6. Tap Erase iPhone.

Fix #7: Contact Apple support

If all else fail, you must contact Apple support so they can take a look at your iPhone. There’s a good chance that there might be a hardware malfunction that prevent wifi service from working on the device.
