Overview

Forgetting a Wi-Fi network removes the saved connection details from your device. This is useful when a wireless password has changed, a connection keeps failing, or you no longer want your device to auto-connect to that network. Microsoft, Apple, Google, and Chromebook all provide built-in ways to remove saved networks.

Instructions

Windows 11

1. Open Settings
2. Go to Network & internet, select Wi-Fi, then choose Manage known networks
3. Find the network you want to remove and click Forget.

Microsoft also notes you can reconnect afterward by selecting the network again and entering the password.

Mac

1. Open System Settings and select Wi-Fi in the sidebar
2. To forget the network you are currently connected to, click Details and then Forget This Network
   1. To remove an older saved network:
      1. Go to Advanced
      2. Locate it in the known networks list, and remove it

Apple also documents slightly different steps for earlier macOS versions using System Preferences in their support article. 

iPhone and iPad

1. Open Settings and tap Wi-Fi
2. Tap the info button next to the network, then choose Forget This Network

Apple recommends this when you need to remove a saved connection and reconnect with updated settings or credentials.

Android

1. Open Settings
2. Go to Network & internet
3. Click Internet.
4. Open your saved networks, select the one you want to remove, and tap Forget

Google’s support documentation notes that menu wording can vary a little by device, but the process is generally the same.

Chromebook

1. Sign in
2. Select the time in the bottom-right corner
3. Open Settings
4. Go to Network, select Wi-Fi, then Known networks
5. Find the saved network, select More, and choose Forget.

Google documents the same general process for ChromeOS devices and Pixel Slate.
