Fix: iPhone won’t connect to Wi-Fi

iphone wont connect to wifi

There aren’t many things that are more annoying than a situation when your iPhone won’t connect to a Wi-Fi network. Especially when you’re home, and you’re forced to consume the precious MBs or even GBs from your cellular plan.

That’s why we’ll try to find a solution for when your iPhone won’t connect to a Wi-Fi network here. Since iOS 15 is the latest iOS version (at the time of writing), I composed this article to be compatible with it, but you can apply all these solutions to older (and probably newer when the time comes) versions of iOS, since nothing’s really changed in the way we deal with this kind of problems. So, let’s begin…

Solution 1: Toggle Wi-Fi off and on again

Yes, this has been the most generic solution in the history of tech. But the reason for that is because it sometimes works. So, before trying anything else, just go ahead and turn Wi-Fi off and on again. It can’t hurt, but it may help.

Here’s how to do that, in case you’re not sure:

  1. Go to Settings.
  2. Tap Wi-Fi.iphone wont connect to wifi toggle
  3. Tap the Wi-Fi switch twice. Once to turn it off, and again to turn it on.

Solution 2: Update  your iPhone

I want to say that a bad update is probably the reason you can’t connect to Wi-Fi. iPhones are made to work, and the one thing that’s most likely to disrupt that is a faulty update. Especially if we take into account that iOS updates have been a mixed bag throughout history. Most of them introduce new features and improve your iPhone, but some updates can really mess up everything.

If you suspect your Wi-Fi connection doesn’t work because of the latest iOS 15 update you installed on your iPhone, your best bet is to probably wait for a new update. Unless there’s a specific solution that applies to your iOS 15 version (do a little research). But if there’s no specific solution, you can either try other solutions from this article (although I can’t promise any of them would work) or just wait for Apple to release a patch.

Solution 3: Check the Airplane mode

If you’ve accidentally turned on the Airplane mode, you won’t be able to connect to Wi-Fi. So, go ahead and check if it’s off: Here’s how to do that:

  1. Open Settings.iphone wont connect to wifi airplane mode
  2. Make sure the Airplane Mode option is toggled off.

Solution 4: Reboot your iPhone

The principle is the same as in the first solution, but it works on a deeper level. So, instead of rebooting the Wi-Fi feature, let’s go and reboot the whole phone. Maybe that will resolve the problem and allow us to connect to a Wi-Fi network again.

To reboot your iPhone, press and hold the Side button + the Volume Down button at the same time, until the Power off slider appears. Just drag the slider to the right, and your iPhone will power off. Turn on your iPhone again, and try to connect to a Wi-Fi network again. If you succeed, you’re done. If not, well, proceed to the next solution.

Solution 5: Re-connect to a Wi-Fi network

Since we’re rebooting and reconnecting, you may as well reconnect to a particular Wi-Fi network, if that’s the only network you can’t connect to. Just make sure you know that network’s password, so you can connect to that network again without problems.

Here’s what you need to do:

  1. Go to Settings.
  2. Tap Wi-Fi.
  3. Tap the Wi-Fi network you’re trying to connect to.iphone wont connect to wifi forget network
  4. Go to Forget This Network, and confirm by tapping Forget.

Now, go ahead and try to connect to that Wi-Fi network again. Maybe you’ll be of better luck this time.

Solution 6: Check the router

If you’re having problems with a Wi-Fi network in your own home, it’s a good idea to check your router. Maybe something inside the router settings isn’t set properly, and that’s exactly what’s preventing you from connecting to the Wi-Fi network.

Since there are so many different router manufacturers and models and can’t exactly tell you what to do. So, you’ll have to either check the router’s manual or contact your internet provider for help.

Solution 7: Reset Network Settings

If none of the previous solutions resolved the problem with Wi-Fi on iOS 15, you can try resetting the network settings altogether. Just remember that if you choose to do so, you’ll be reverting each setting to its original state, so you might need some time to get everything back in order.

So, think twice before resetting the network settings. Nevertheless, if you want to try this solution, here’s what you need to do:

  1. Go to Settings.
  2. Head over to General > Reset.reset network settings iphone wont connect to wifi
  3. Tap Reset Network Settings.
  4. Enter your passcode to confirm.

That’s about it. I hope at least one of these solutions helped you resolve the problem with Wi-Fi on iOS 15. If you did or you have an alternative solution to recommend, tells us in the comments section below.
