AT&T requires you to use their gateway for their fiber service. You can disable the router portion (pass through mode) and connect a much better router to it. There is also a way to use your own modem but AT&T will still charge you the monthly fee regardless of what you do once you signup for the service.Jan 21, 2021
Does AT&T fiber use a router?
You can connect and use your own router to AT&T Fiber. But, you need to use the gateway of AT&T when you want to connect your own router to AT&T fiber. You should use the Fiber Modem of AT&T with a DD-WRT Flash Router in the setup of a single router.Oct 1, 2021
