Which method allows resetting an access point by pressing a button?

The method that allows resetting an access point by pressing a button is typically known for its simplicity and direct approach. When you physically press the designated reset button on an access point, it triggers a factory reset process. This action typically restores all settings to their original factory state, which can be crucial for troubleshooting issues, starting fresh configurations, or removing any forgotten passwords.

This method is often preferred by users because it does not require any technical knowledge beyond knowing which button to press. It provides a straightforward way to regain access to the device when needed, especially in cases where access through the software interface is not possible due to misconfigurations or lost credentials.

In contrast, power cycling involves turning the device off and back on again, which can resolve minor connectivity issues but does not actually reset configurations. A firmware update is aimed at improving the software of the device but also doesn't reset settings. Thus, the reset button method is specifically designed for reverting the device to its default settings, making it the correct answer.
