FAQ

A gigabit cable modem is a device that connects your home network to your internet service provider (ISP) and supports internet speeds up to 1 gigabit per second (Gbps). These modems are ideal for high-speed internet plans and activities like streaming 4K videos, online gaming, and managing multiple connected devices.

Yes, to take full advantage of a gigabit cable modem's capabilities, you need to have an internet plan from your ISP that offers speeds up to 1 Gbps. If your plan offers lower speeds, the modem will still work, but you won't experience gigabit-level performance.

Most gigabit cable modems are compatible with major cable internet providers such as Xfinity, Spectrum, and Cox. However, it's important to check the modem's compatibility list or consult your ISP before purchasing to ensure it will work with your specific service.

Yes, gigabit cable modems can be connected to most Wi-Fi routers. This allows you to create a wireless network in your home while benefiting from high-speed internet provided by the modem.

When selecting a gigabit cable modem, consider features such as DOCSIS version (preferably DOCSIS 3.1 for the fastest speeds), the number of Ethernet ports, compatibility with your ISP, and any additional functionalities like built-in Wi-Fi or phone support if needed.
