xfinity docsis

The listings include both DOCSIS 3.1 and DOCSIS 3.0 cable modems.

Advertised wired speeds in the listings range from about 1 Gbps (gigabit) up to multi-gig levels such as 2.5 Gbps.

Some listings are modem/router combos that include built-in Wi‑Fi (examples list Wi‑Fi 6 or Wi‑Fi 5), while others are modem-only units that provide no wireless networking.

Ethernet port counts vary across the listings, typically ranging from a single Gigabit Ethernet port up to five ports on higher-end models.

Some listings highlight dedicated multi-gig Ethernet ports (for example 2.5 Gbps) and others support link aggregation to combine two Gigabit ports for higher throughput (commonly cited as up to about 2 Gbps).

Some modems explicitly list Xfinity Voice support and include telephone ports; one listing specifically notes two telephone ports and being built for Xfinity Voice.

Several listings note easy self-activation: plug the modem in and follow the on-screen or app setup prompts to activate service without a technician visit.

The listings reference Xfinity plan upload examples such as 200 Mbps, and some multi-gig modem listings advertise upload capability up to 1 Gbps.

Built-in Wi‑Fi speeds listed range roughly from 1,100 Mbps up to about 2,700 Mbps; one AC1900 model is listed at around 1,900 Mbps.
