If you wish to navigate to settings and configure the router you must know the
ATT router access code. You do have a default access code and the option to change it. Go to the settings of the router and click on system info. Then, click on access code. Now, type the current or default access code, which is 192.168.0.1 in the browser. You can now select a new access code. Type it again to confirm it. You have this option so that you can change the credentials to something you find easy to remember.
