Frequently Asked Questions
What Cable Modem Works Best With At&t Fiber?
AT&T Fiber typically requires a modem compatible with their network. However, cable modems like NETGEAR Nighthawk CM1200 are designed for cable providers, not fiber. For AT&T Fiber, a fiber ONT with a compatible router is needed instead of a cable modem.
Can I Use Docsis 3.1 Modems With At&t Fiber?

What Ethernet Ports Should A Modem Have For At&t Fiber?
AT&T Fiber connections benefit from gigabit Ethernet ports (1 Gbps or higher). Devices like NETGEAR modems with 4 x 1G ports allow fast wired connections, but fiber requires a compatible ONT and router setup.
