About
AT&T Fiber requires specialized Gateways that utilize a unique authentication certificate to access the network. Unlike standard cable modems, these units often combine an Optical Network Terminal (ONT) with a high-speed Wi-Fi router to support symmetrical gigabit speeds. Looking for DSL? If your service runs over a traditional copper phone line, browse our AT&T DSL Modems and Gateways to find the right fit for your home.
