Regularly check for and install firmware updates from the manufacturer, as these often contain critical security patches. Consider disabling remote management features if you do not need them, and set up a guest network for visitors to keep your main network secure. A strong password for your Wi-Fi network should be at least 12 characters long, a mix of uppercase and lowercase letters, numbers, and symbols.
