10 Best Wi-Fi Modems 2025 in the United States

The ARRIS SURFboard SB8200 Cable Modem is a robust choice for users looking for high-speed internet connectivity. It supports the latest DOCSIS 3.1 technology, which offers speeds up to 1 Gbps and is 10 times faster than the previous DOCSIS 3.0 standard. This makes it an excellent option for high-bandwidth activities like HD multimedia streaming and online gaming, as it ensures minimal lag and rapid data transfer.

The modem features two 1-Gigabit Ethernet ports, allowing you to connect it directly to a Wi-Fi router or other devices for a wired internet connection. This setup can appeal to households with multiple users or devices requiring steady and fast internet access. Its ease of setup is another plus, with the SURFboard Central App guiding users through a simple plug-in and activation process. Compatibility with major U.S. cable providers, including Comcast Xfinity, Cox, and Spectrum, means you can use it with most popular ISPs without issues.

It is worth noting that this modem lacks built-in Wi-Fi, necessitating an additional Wi-Fi router for wireless connectivity. This extra step could be inconvenient for users seeking an all-in-one solution. Additionally, it does not have a telephone port, which might be a drawback for users who need VoIP services. The ARRIS SB8200 also offers significant savings on rental fees from ISPs, making it a cost-effective investment in the long run. If you need a reliable, high-speed modem and don’t mind purchasing a separate Wi-Fi router, the ARRIS SB8200 is a great choice.
