How to Delete a Wi-Fi Network on an iPhone

Clearing Clutter and Solving Connection Issues

Every time you connect your iPhone to a new wireless network—whether it is at a coffee shop, an airport, a hotel, or a friend’s house—your device automatically saves that network’s name and password. This is designed for convenience, ensuring you instantly reconnect the next time you visit that location.

However, over several years of use, your iPhone can accumulate dozens, or even hundreds, of saved networks. This digital clutter is not just untidy; it can cause genuine connectivity problems. If you are standing in a location where your iPhone detects multiple saved networks simultaneously, it might repeatedly try to connect to a weak, unusable signal (like an old hotel Wi-Fi) instead of the strong, reliable network you actually want to use.

In these situations, the easiest solution is to force your iPhone to completely “forget” the problematic network, permanently deleting the saved password and preventing it from ever connecting automatically again.

Method 1: Deleting a Network You Are Currently Near

If you are actively experiencing a problem—for instance, your iPhone keeps connecting to a public “Guest” network instead of your secure office network—you can delete the offending connection in seconds.

1. Unlock your iPhone and tap the grey Settings app.
2. Tap on Wi-Fi.
3. Ensure the main Wi-Fi toggle is turned on so your phone is actively scanning for networks.
4. Look under the “My Networks” or “Other Networks” lists for the specific network you want to delete.
5. Tap the small, blue “i” icon (the information button) located directly to the right of the network’s name.
6. At the very top of the new screen, tap Forget This Network.
7. A warning prompt will appear asking you to confirm. Tap Forget.

Your iPhone will instantly disconnect (if it was connected) and will never attempt to join that specific network again unless you manually select it and re-enter the password.

Method 2: Deleting a Network You Used in the Past

Historically, Apple only allowed you to delete a Wi-Fi network if you were physically close enough to detect its signal. However, in modern versions of iOS (iOS 16 and later), Apple introduced a fantastic feature that allows you to view and delete every single network your phone has ever saved, regardless of your current location.

This is perfect for doing a deep clean of your device and removing old hotel and airport networks.

1. Open the Settings app and tap on Wi-Fi.
2. Look in the extreme top right corner of the screen and tap the blue Edit button.
3. Your iPhone will prompt you to verify your identity using Face ID, Touch ID, or your passcode.
4. Once authenticated, a new screen titled “Known Networks” will appear. This is a complete, alphabetical list of every Wi-Fi network your iPhone remembers.
5. Scroll through the list to find the network you want to remove.
6. Tap the red minus (-) circle to the left of the network’s name.
7. A “Delete” button will slide out from the right side. Tap Delete.
8. Repeat this process for as many networks as you wish to remove.
9. When you are finished cleaning up, you must tap Done in the top right corner to save your changes.

Why Deleting a Network is Good for Security

Beyond solving connection problems, deleting old Wi-Fi networks is an excellent security practice.

Many public Wi-Fi networks (like those in coffee shops) are completely unencrypted. If your iPhone automatically connects to one of these networks while it is in your pocket, a malicious actor on that same network could potentially intercept your data before you even realise you are connected.

By regularly auditing your “Known Networks” list and deleting public hotspots after you have finished using them, you ensure your iPhone only connects to networks you actively trust.
