<p>The following are the things that you can change from the ATT router settings:-</p><p>1. You can change the long, unreadable strings into something smaller yet powerful in replacement of your wifi password for the router.<br />2. You can also change the name of your network which is also known as SSID that will be displayed on other devices.<br />3. You can also change WPA3 encryption which is a high end encryption language that can prevent any data contravention on your network.</p>
