iPhone internet not working after iOS 15 Update? Here how to fix WiFi or 4G internet problems

Internet not working or iPhone won’t connect to Wi-Fi after iOS 15 Update? An iPhone without an Internet connection is nothing but a regular smartphone. Sometimes, internet troubles can make your iPhone a very boring device. If you are not able to connect with cellular data or WiFi on your iPhone, then in this post we will discuss some tips to fix internet problems on the iPhone. We have composed a detailed draft that will walk you through all the internet related troubles that you can face.

Pro Tip: If you are using VPN through the built-in feature or via an app, try disabling it. Sometimes, VPNs also disrupt Internet and Wi-Fi connectivity to an extent.

Internet not working on iPhone

Before fixing the problem, you have to determine the cause of the problem first. We need one part to fix it. Foremost, make sure that you are not able to connect with the internet connection completely.

You can check this by refreshing your mail, you can search app listing on App Store, you can open Safari, etc. If nothing connects, then your internet connection is completely unavailable. However, if you can perform other internet-based functions, but won’t able to connect with Safari, then the problem is with Safari only. This equation can work for any other app also.

Check WiFi-only causing or Mobile internet 4G?

Okay, so if your internet connection isn’t working entirely, then next you have to determine whether it is a problem with cellular data or wifi. It is a simple test to run and diagnose the problem.

You have to make sure that you are connected to the right wifi network. Look at the top left side of your iPhone screen and identify your network strength by looking at the five blobs. One blob means low signal and five means high signal. If it’s the familiar ‘Wi-Fi’ icon, with three concentric quarter-circles, then hey presto, you’re on Wi-Fi. If not, you might see 4G or 3G, which should ensure a good connection; or GPRS or Edge (or E), which probably won’t, but you may still able to load up the odd web page if you’re patient

If you don’t see any of the WiFi or cellular data signals, then you are not connected to the internet. So, if your wifi or cellular data is giving you trouble, then you can following tips to fix the internet problem on your iPhone.

Apply this if Cellular Data causing the issue

Check mobile data switch – First, make sure that mobile data is switched on your device by going to Settings and then Mobile Data. Check if the slider in front of mobile data is green, if not, then tap over it.

Data roaming – If you are traveling internationally, then make sure that Data Roaming option is switched on your iPhone. The Mobile data roaming option is present below the Mobile Data option. Just make sure this option has a green bar on the front.

Cellular dead spots – If the reception of cellular data is not strong in your area, then you should try to connect from someplace else as even after so much development, there are few places where mobile data won’t work.

Data Limit – You should contact your mobile data service provider and make sure that your monthly data limit isn’t expired. In the iPhone, there isn’t any system present where you can check your data consumption level. You have to contact your service provider and confirm your data balance and if you have low data balance, then you should immediately recharge again to resume services.

Restart your iPhone – Restarting iPhone has been a solution for numerous iPhone related problems. By pressing the home button and the power button together, you can easily restart your iPhone and it will most of the time fix your problem.

  • For iPhone 7 and later, hold the volume down button and the Power button at the same time.
  • For iPhone X/8/8 Plus users, press and release the Volume Up button, and then the Volume Down button. After that, hold the Power button for some time.

Reinsert SIM – You can use the provided SIM tray tool to take out your SIM and then reinsert it. This will probably solve the problem for you as sometime SIM gets out of place or breaks.

Check Carrier Settings – You can try to check your carrier settings and make sure that they are up to the mark. It is slightly troublesome for you as your device is not over the internet. But, you can check the carrier update settings before your phone went offline by going to Settings > General > About.

Call your Service Provider – If you won’t able to fix your cellular problem even after trying all the methods, then you should call your data service provider and ask them to fix your problem as something server of the provider companies is down.

Apply this if WiFi causing the issue

Honestly speaking, this is the same situation as compared to cellular data, but it is a less complicated situation. First of all, we will cover all the basics before moving to the reboot. So, go to Settings and check whether the WiFi slider has a green bar and make sure that you are connected to your local network. It is not possible to connect with the unknown server, but if somehow you have managed to connect with the unknown server, then immediately unhook it.

If everything is working fine, then you can use some other device to test the connectivity of the wifi network. If that didn’t connect, then the problem is with your router or broadband service provider and your device is perfectly fine.

However, if this doesn’t work for you, then you can reboot your iPhone. Once it’s back up and running, go to Settings > Wi-Fi, and rejoin the networks.

Toggle Airplane Mode

Turning on Airplane Mode and then turning it off after a few seconds might solve the 4G/3G or LTE connectivity. To do so; swipe up iPhone Screen (On iPhone X Series, swipe down from the top-right corner) and Turn On and Off Airplane Mode.

Reset Network Settings

This will wipe out any saved Wi-Fi networks while resetting your cellular data settings to their defaults.

  • Open the Settings app.
  • Scroll down and tap the “General” menu option.
  • Scroll to the bottom and tap the “Reset” menu option.
  • Choose “Reset Network Settings” in the middle of the screen.
  • Enter your iPhone or iPad’s passcode to authorize the reset.
  • Tap “Reset Network Settings” to confirm the reset
  • Now again connect to the wifi network and check whether it helps.

Switch to Google DNS

By default, all Wi-Fi networks configure the DNS automatically. However, sometimes changing it to OpenDNS or Google DNS helps in resolving internet problems.

  • Open Settings Settings on your phone, go to Wi-Fi.
  • Tap on the Wi-Fi network that is giving you trouble.
  • Tap on Configure DNS and choose Manual.
  • Delete the entry under DNS servers and first enter Google DNS i.e., 8.8.8.8. Then, enter 8.8.4.4 by tapping on Add Server.
  • Alternatively, use OpenDNS values: 208.67.222.123, 208.67.220.123.
  • Now check if this helps

Do a factory reset

If resetting network settings won’t help, the next logical troubleshooting step is to perform a factory reset. As the name suggests, all software settings will be returned to their defaults. If you haven’t tried doing it before, here’s how:

  1. Create a backup of your important files via iTunes or iCloud.
  2. Sign out of your iCloud account (if applicable).
  3. Go to Settings Tap on General.
  4. Then Tap Reset and tap Erase All Content and Settings.
  5. Enter your passcode to authorize the operation.
  6. Tap “Erase iPhone” to confirm the operation.

What if the iPhone won’t connect to Wi-Fi?

If your iPhone is having trouble connecting to one specific Wi-Fi network, try forcing the phone to “forget” that specific network. Go to Settings, Wi-Fi. Touch the right-pointing arrow next to the network name, and on the next screen choose to Forget this Network.

Now again try to connect to the WiFi network and check if this helps.

So, these are the easy tips to fix the internet on the iPhone on both wifi and cellular data. If none of the above-mentioned methods work for you, then you should contact Apple support and get your iPhone checked.
