4. Check your Wi-Fi Router

Sometimes when your Wi-Fi is not working on iPhone 16, the issue isn’t with your phone, it’s the router that’s acting up. If you notice other devices in your home also struggling to connect, chances are your router might be the problem. It’s always worth checking to avoid wasting time troubleshooting your phone.

First, check if other devices are connected to the Wi-Fi. If none of them are working, unplug the router from its power source and wait about 30 seconds. After that, plug it back in and let it fully reboot. If that doesn’t solve the problem, update the router’s firmware or move it to a more central location for better coverage.

5. Turn off VPN

At times, a VPN may disrupt your device’s ability to maintain a stable connection, particularly if the VPN server is slow or facing issues. Try disabling it so your phone can connect directly to the Wi-Fi network without any added layers that might cause interruptions. You should only try this fix if you have determined the Wi-Fi is working fine on other devices and only causing issues on your iPhone.

If you’re using a third-party VPN app on your iPhone, you can turn it off from within the app. For a built-in VPN client, follow these steps:

  1. Go to Settings > General.
    navigate-to-settings-general
  2. Tap VPN & Device Management > VPN.

  3. Turn off the toggle next to VPN Status.

6. Disable Location for Networking Services

Many users have reported that they’ve solved their issues by disabling Location services for networking. This only affects how my location is used for Wi-Fi, so it doesn’t completely turn off Wi-Fi.

  1. Open the Settings app.
  2. Tap Privacy & Security > Location Services.

  3. Tap System Services, then tap the Networking & Wireless toggle to turn it off.

7. Turn Off/On Wi-Fi Assist

If your iPhone 16 isn’t connecting to Wi-Fi, turning off Wi-Fi Assist and then turning it back on can help. By doing this, you can force your phone to re-establish a stronger connection between Wi-Fi and cellular data. It’s as though the reset refreshes the signal and lets the phone pick the best option for connectivity.

  1. Go to Settings > Cellular.
  2. Disable the Wi-Fi Assist toggle.

  1. Open the Settings app on your iPhone.
