Some iPhone 15 users have said they are unable to connect to Wi-Fi networks. Affected users keep getting “No Internet Connection” error messages when they want to use Internet-dependent apps like Safari, Twitter, FaceBook, etc. In this article, we explain what to do when your iPhone 15 won’t connect to Wi-Fi.
KEY TAKEAWAYS
if your iPhone 15 won’t connect to Wi-Fi, start by restarting your Wi-Fi, then check for VPNs interfering, time and date settings, DNS errors, outdated software, or network settings. You might also want to try restarting your device.
Here are some of the characteristics of this problem:
- It seems that the phone may connect at first but then keeps disconnecting itself from Wi-Fi randomly.
- It also seems that the problem does not occur on just one Wi-Fi network, instead, Wi-Fi failure happens on all networks. This rules out the possibility that the problem is the Wi-Fi connection.
- Further, it seems that the problem is with the iPhone, as other devices can connect to the same Wi-Fi without an issue.
- All iPhone 15 models (iPhone 15, 15 Plus, 15 Pro, 15 Pro Max) seem to be affected.
- Lastly, it appears that the iPhone 15 Wi-Fi settings do not show any indication that the Internet is not working. It looks like Wi-Fi is connected, but there is no Internet.
- The cellular data connection is not affected.
If you are experiencing this issue, you won’t be able to browse the web, download apps or use any other app or service that requires an Internet connection. Try the following steps, in order, to fix this issue. After each step, check your iPhone to see if it can connect to the Internet over Wi-Fi.
Restart Wi-Fi
If your iPhone 15 won’t connect to Wi-Fi, the first thing to try is easy – toggle Wi-Fi off and then turn it back on again. This will force it to scan for available networks again.
- Go to Settings.
- Tap Wi-Fi and ensure that Wi-Fi is enabled. If it is already enabled, turn off Wi-Fi and then turn it on again.
Double Check the Wi-Fi Password
To connect to most Wi-Fi routers, you’ll need a password. This password is set by the owner of the router or access point. If there’s even a one character typo in the password, your iPhone 15 won’t connect.
So make sure you have the right Wi-Fi password: Ask for it again, if necessary, to double check, or write it down twice on a piece of paper. Then re-enter it in the Setup and see if that helps. If not, move ahead to another step.
See if the Connection Requires a Wi-Fi Login Page
Some businesses (such as hotels, restaurants, airlines, and more) provide an "open" Wi-Fi network that restricts access using a Wi-Fi login page or portal in a web browser. These login pages make you sign in with a special username and password provided by the business.
If you’ve connected to a Wi-Fi access point in the settings on your iPhone but aren’t seeing any internet access, try opening the browser on your iPhone and visiting any website. If the business uses a login page, you’ll usually be automatically redirected to the login page where you can enter the credentials properly.
Restart your iPhone
Under the hood, your iPhone isn’t that much different from a Mac or Windows PC, and you may have already encountered problems with those devices that are solved by a simple reboot. The same is sometimes true with an iPhone.
- Press and hold the right-side button and either of the volume buttons until the Slide to power off control appears.
- Drag the slider from left to right.
- Wait at least 30 seconds for your device to fully power down.
- Press and hold the button on the right side of your iPhone until you see the Apple logo appear.
- Your device will boot up and return to the lock screen after a few seconds.
- Swipe up and enter your passcode to unlock your device.
Restart your modem/router.
If you’re still having trouble connecting to your Wi-Fi router—and you have control over the router or access point itself—you can try restarting it to see if that helps clear any temporary bugs or error states that might be making it malfunction. Similar to restarting your iPhone, restarting your router forces it to reload its settings from scratch, which can solve a variety of problems.
To restart the modem/router, simply unplug it/them from the power outlet, wait 10 seconds and then plug it back in.
Update your iPhone
If your iPhone 15 still isn’t connecting to Wi-Fi after trying the steps above, the next thing to do is update your phone to the latest version of iOS. If you have enough cellular data, then Go to Settings >** General** > Software Update to check for updates.
Enable Auto-Join
Ensure that Auto-Join is enabled. Go to Settings > **Wi-Fi **> [your network] > and turn on Auto-Join.
Forget the Wi-Fi Network and try again
If your iPhone 15 is still not connecting to Wi-Fi, forget your Wi-Fi network and then reconnect. When you forget your Wi-Fi network, you will need to reenter its password to connect again. Go to Settings > **Wi-Fi **> [Wi-Fi network name] and tap Forget This Network.
Ensure Date, time, and time zone are correct
Check the date, time, and time zone to ensure they are set correctly. Go to Settings> **General **> Date & Time and turn on Set Automatically.
Are you using custom DNS?
Are you using custom DNS instead of the default DNS set by your connection? If so, there may be a problem with the DNS servers.
- Go to Settings > Wi-Fi > [Wi-Fi network name].
- Scroll all the way down and tap Configure DNS under the DNS section.
- Does this setting say “Automatic” or “Manual?” If it says “Manual,” change it to “Automatic.” If this does not make a difference, you can revert back to “Manual” if you want.
Are you using VPN?
VPNs are useful and almost certainly worth paying for, but they can cause all sorts of problems too. The easiest way to rule out your VPN as a cause is to disable it and try again. Here is how you can check these:
- Go to Settings
General > VPN. If it says Connected, turn it off. Then tap the (i) info button next to the VPN and tap Delete VPN. - Go to Settings >** General** > Profile (if this option does not appear, it means there is no profile installed). Delete any profile that shows.
If, after turning off VPN and deleting it, you see that Wi-Fi is working, then you have two options:
- Stop using VPN.
- If you do not want to stop using VPN, then you can try to reset your network settings (see the next section). You can also contact the VPN service provider to see if they can help.
Reset network settings
If you’ve tried everything and your iPhone 15 is still not connecting to Wi-Fi, consider resetting your network settings. Doing this will restore settings like DNS and proxy configurations to factory defaults, and you’ll also lose all of your saved Wi-Fi credentials for any wireless networks you have added to your device.
If you’re sure you want to do this, tap Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. Follow the onscreen instructions.
Other options
After you follow all the steps, you can be sure that you have done all the troubleshooting steps to fix this problem. This means that if your issue continues on your iPhone 15, your problem may be a deeper, possibly hardware-related problem. It is best to contact Apple support to see if there is a manufacturing defect. If so, Apple will fix it. You may also have AppleCare. Thus you should contact Apple to see what your options are.
