How can my TP-Link router be reset? Find the "reset" button on your TP-Link router to reset it. Usually, it is sunken into the unit's bottom or rear. Press and hold the button with a paper clip for 30 seconds or until the lights are turned off. After that, the TP-Link router will shut down before turning back on. The factory default settings will then be used. This implies that your current settings for the SSID (network name), Wi-Fi password, and other items will be changed back. After that, you'll need to adjust it via the admin panel or the Tether app.
