The AT&T router web interface is the control panel for your router, where all the ATT router settings are stored and changed. To make changes to your network, you'll need to log in to your AT&T router. Following are the instructions to connect to your AT&T router's interface for configuration and diagnostics.
1. Make sure you are connected to your AT&T router to reach the setup pages of your AT&T router. You'll need to be connected to its network. So, start by clicking to the network, either through WIFI or through an ethernet cable. 2. Open your web browser, navigate to 192.168.0.1. 3. Enter the username and password for your AT&T router in the username and password field. That's it. You can now configure anything you want on the router.
