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 support all provide built-in ways to remove saved networks. |
Microsoft also notes you can reconnect afterward by selecting the network again and entering the password.
Apple also documents slightly different steps for earlier macOS versions using System Preferences in their support article.
Apple recommends this when you need to remove a saved connection and reconnect with updated settings or credentials.
Google’s support documentation notes that menu wording can vary a little by device, but the process is generally the same.
Google documents the same general process for ChromeOS devices and Pixel Slate.
