If your iPhone keeps disconnecting from Wi-Fi, it can be frustrating, especially when streaming, working, or attending video calls. Fortunately, iOS provides several tools and settings to fix frequent Wi-Fi disconnections. In this guide, we’ll walk you through step-by-step solutions to stabilize your Wi-Fi connection on iPhone.

1. Restart Your iPhone and Router

A simple restart often resolves temporary network issues:

  1. Turn off your Wi-Fi router and wait about 30 seconds before turning it back on.

  2. On your iPhone, hold the Side button + Volume Up (or Down) depending on your model, then swipe Power Off.

  3. Wait 10 seconds, then power it back on.

  4. Reconnect to your Wi-Fi under Settings → Wi-Fi.

This clears temporary IP conflicts and improves connectivity.

2. Forget and Reconnect to Your Wi-Fi Network

Sometimes saved Wi-Fi credentials can become corrupted:

  1. Go to Settings → Wi-Fi.

  2. Tap the “i” icon next to your connected network.

  3. Tap Forget This Network → Forget.

  4. Reconnect by entering your password.

💡 Tip: If your router has both 2.4GHz and 5GHz bands, try both. 2.4GHz is more stable at longer distances, while 5GHz is faster in close range.

3. Disable Wi-Fi Assist

iOS includes a feature called Wi-Fi Assist that automatically switches to mobile data when Wi-Fi is weak, which may cause disconnections:

  1. Go to Settings → Cellular → Wi-Fi Assist.

  2. Toggle it OFF.

This ensures your iPhone remains connected to Wi-Fi without automatically using mobile data.

4. Reset Network Settings

If issues persist, resetting network configurations often helps:

  1. Go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.

  2. Confirm the reset.

  3. Reconnect to your Wi-Fi network.

⚠️ Note: This will erase saved Wi-Fi passwords, VPN settings, and Bluetooth connections.

5. Check for Software Updates

Apple often releases fixes for Wi-Fi stability in iOS updates:

  1. Go to Settings → General → Software Update.

  2. Install any available updates.

Keeping iOS updated ensures compatibility with modern routers and security patches.

6. Advanced Tip: Change DNS Settings

Using a reliable DNS can stabilize Wi-Fi connections:

  1. Go to Settings → Wi-Fi → Tap “i” next to your network → Configure DNS → Manual.

  2. Enter:

    • DNS 1: 8.8.8.8

    • DNS 2: 8.8.4.4

  3. Save the settings and reconnect.

This often improves stability, especially on networks with slow DNS response times.

7. Final Tip

If none of these steps work, you may need to perform a factory reset (after backing up your iPhone). Persistent disconnections could indicate hardware issues with the Wi-Fi antenna, so visiting an Apple Store or authorized service center may be necessary.
