27 Ways to Fix iPhone 15 Pro and 15 Pro Max Wi-Fi Not Connecting or Working Issue

Now that you know the reasons behind this issue, let’s take a detailed look into how you can fix this issue. We will resolve all the internet connection issues and proceed with the iPhone configuration issues. Let’s dive in.

Fix 1: Check your Internet Connection

First, let’s ensure your iPhone and the internet are on good speaking terms. Sometimes, it’s just a matter of a loose connection or a hiccup in the network. We’re giving it a gentle nudge to fix it.

Make sure your internet service is active and working. Sometimes, the issue might be a weak or disconnected connection. Verifying this connection helps pinpoint the problem and proceed to the next steps if needed.

Fix 2: Restart your Router

Have you ever had a long day and needed a moment to rest? Your router does, too! A quick restart is like a rejuvenating nap for your router. It clears any glitches and gives it a fresh start, often solving those pesky Wi-Fi issues.

Restarting your router can address various connectivity issues. It clears temporary glitches, re-establishes connections, and refreshes settings. Follow the steps to restart your router:

1. Unplug your router from the power cord.
2. Wait for a few minutes for all the power to drain out.
3. Now, plug in your router and see if the Wi-Fi issue has been resolved.

Fix 3: Check your Router Settings

Think of your router settings as a control center for your Wi-Fi. Sometimes, a setting might have gone a bit off track. These settings may include firewall configurations or restricted access.

Ensuring the router settings align with your iPhone’s requirements is essential for a smooth and uninterrupted connection. Go into your router settings using the IP address and make sure all the settings are correct.

1. Search for your router’s IP address. It should be written on the back.
2. Enter the IP address in a browser while connected to the Wi-Fi.
3. Enter the username and password (also written on the back of your router) and log in.
4. Check all the settings and make sure they are configured correctly.

Fix 4: Disable MAC Address Filtering

The MAC address is like filtering as a bouncer at a club, allowing only certain devices in. In other words, MAC address filtering is a security feature on routers that can inadvertently block your iPhone from connecting.

Disabling this filtering temporarily allows your iPhone to connect, indicating whether the filtering was causing the issue. Follow the steps below to disable this filter.

1. Search for your router’s IP address. It should be written on the back.
2. Enter the IP address in a browser while connected to the Wi-Fi.
3. Enter the username and password (also written on the back of your router) and log in.
4. Go to MAC Address Filtering or Blocked Devices or a similar option and ensure your iPhone’s MAC address is not listed there.

You can find your MAC address here:

1. Open the Settings app on your iPhone.
2. Tap on Wi-Fi.
3. Tap on the “i” next to your Wi-Fi network.
4. Your MAC address is listed next to Wi-Fi Address.

Fix 5: Check for Router Firmware Updates

Just like your phone gets updates, so does your router. Sometimes, an update is all it takes to smoothen out the wrinkles in its performance. We’re making sure your router is not missing out on any important software upgrades.

Router manufacturers often release updates to improve performance and fix bugs. Ensuring that your router’s firmware is up to date can resolve compatibility issues with your iPhone and potentially enhance your Wi-Fi connection. Follow the steps below.

1. Search for your router’s IP address. It should be written on the back.
2. Now, enter the IP address in a browser while you are connected to the Wi-Fi.
3. Enter the username and password (also written on the back of your router) and log in.
4. Check for Firmware Updates and install them, if available.
5. Once the update is installed, simply restart your router (as directed in Fix 2).

Fix 6: Reset your Router

When all else fails, a good old reset can do wonders. It’s like a mini-vacation for your router, wiping out any issues and giving it a clean slate. After this, your iPhone and Wi-Fi should be back on talking terms.

Resetting your router involves restoring it to its default settings. This is a more comprehensive step than a simple restart and can resolve complex network problems. It’s a measure taken when other basic troubleshooting steps don’t work. Follow the steps below.

Note: Resetting your router will delete all the configurations and reset your Wi-Fi’s SSID and password.

1. Find the reset button on your router. It is usually located on the back and inside a hollow space.
2. If the button is inside a hollow space, use a pin to press and hold the button for a few seconds. This will reset your router.

Guest Wi-Fi networks sometimes have different authentication processes. Verifying that your iPhone is correctly authenticating on a guest network is crucial, as incorrect authentication can lead to connection failures. Sometimes, a little adjustment here can make a big difference in your iPhone’s ability to connect. Follow the steps below.

1. If you are using a guest network, you should see a notification saying you need to enter your details.
2. Tap on that notification, and fill in your details.
3. After you have filled in your details, you should be able to access the internet.

Fix 8: Contact your ISP

When things get really complicated, it’s time to call in the experts – your Internet Service Provider (ISP). There could be issues at their end that are affecting your connectivity, and they might need to troubleshoot or reset your connection remotely.

Question your ISP if there is an ongoing outage and how much time it’s going to take to fix the issue. After the said time has passed, check your internet connection again and see if the issue has been resolved. If not, contact your ISP again and ask for a resolution.

Fix 9: Try Using Another Wi-Fi Network

Trying to connect to a different Wi-Fi network helps determine if the problem lies with your iPhone or the specific network. If your iPhone connects successfully to another network, then the issue may be with the original network. Follow the steps below.
