Always confirm with your provider that the C7500 will activate on your specific service plan before ordering. For help choosing the right device, see our full lineup of cable modems.
The C7500 delivers combined wireless speeds up to 3.2 Gbps across its 2.4 GHz and 5 GHz bands. Its 24x8 channel bonding uses 24 downstream and 8 upstream channels for fast, stable cable internet. Four Gigabit Ethernet ports connect wired devices like gaming consoles, smart TVs, desktop computers, and network printers.
Two USB ports let you share storage drives or printers across the network. WiFi coverage reaches up to 3,000 square feet and supports up to 45 simultaneous device connections, making the C7500 a solid fit for medium to large homes.
